An initial list of 775 exceptional plants has been compiled using information from the Seed Information Database, the list of North American exceptional species compiled by Helm-Wallace (2015), targeted literature search, and expert input. It includes both threatened and non-threatened exceptional species, and currently represents 3% or less of the number of predicted exceptional species globally. Thus, this list is a working list and will require input from researchers worldwide to continue to grow. If you have information on a species that should be added to the list or have any additional information on species that are already listed, please submit that using the form below. Updated versions of the list will be posted periodically.

Azadirachta indica | Meliaceae | Azadirachta indica | No | Yes | No | No | Azadirachta indica: The neem tree is very drought & heat resistant (annual rainfall as low as 130mm & long dry seasons, absolute minimum temperatures of 0°C to 15°C; Tewari, 1992). MCS =34-41 %. The fruit is a drupe containing one (rarely two) seeds. Neem has been variously classified as orthodox, intermediate or recalcitrant with experimental results extremely variable e.g. seeds tolerate desiccation to 10-11% mc either by air-drying at room temperature (26°C to 28°C) or by sun drying (30°C to 34°C) for 8 days, but viability is reduced from 85 % to 60 % and 45 % after one month hermetic air-dry storage at room temperature and at 6°C, respectively (Ezumah, 1986); viability is maintained during 4 months open storage at room temperature but drops to 50 % after 6-7 months (Nagaveni et al., 1987); viability can be maintained at 4°C and 5-8 % mc for up to 5 years (Roederez & Bellefontaine, 1989); complete viability loss occurs in either hermetic storage or open storage at 5°C within 1-4 months, whilst 15 % germinate after 6 months storage of fresh seeds in perforated polythene bags at 15°C (Maithani et al., 1989); seeds tolerate desiccation to 9 % mc, viability is halved on desiccation to 6 % mc and completely lost on desiccation to 2.4 % mc, no loss in viability occurs following 100 days hermetic storage with 6 % mc at 15°C and 0°C, but none survive this period at -20°C, no loss in viability after 8 months hermetic storage at 10°C with 6.5 % mc, while none survive at -20°C with this mc (SSLR); long-term storage under IPGRI preferred conditions at RBG Kew, WP, oldest collection 13 years; germination change 78 to 94%, 2 years, 1 collection. Desiccation tolerant to 11.8 % mc, desiccation sensitive below this level and total viability loss by 5.9 % mc (Varghese and Naithani, 2000). Desiccation tolerant to 3.2 % mc, increased longevity as temperature is decreased from 35 to 25 to 15°C, but rapid drop in viability at 5°C and below (Nayal et al., 2000). Recent work has gone a long way to explaining the contradictions in the above studies. Firstly, developmental maturity affects storage longevity, with seeds from yellow fruits maintaining viability for longer than seeds from brown or green fruits (Sacandé et al., 1998). Secondly, at >=10 % mc, neem is chilling sensitive, with viability maintained for longest (but not >2 yrs) at 10-15°C (ibid). When mc is reduced to 4-8 % mc, chilling sensitivity is removed, with 40-60 % viability after 2 yrs storage at a range of temperatures between 20 and –20°C. However, at lower mc’s, seeds become particularly sensitive to imbibitional stress and often die during rehydration. This can be partially overcome by imbibition at high temperatures of >25-30°C (ibid). The observation that seeds can survive desiccation to ca 4 % mc, freezing at –20°C and rehydration (with care) suggests that seeds from mature yellow fruits are orthodox in behaviour (Sacandé et al., 1998). This is supported by seed chemistry, with oligosaccharide and phospholipid levels and glutathione responses in slowly dried seeds more similar to those of orthodox than recalcitrant species. The increases of these compounds suggest that slowly dried fresh seeds have the ability to undergo a post-maturation process associated with the acquisition of the capability for desiccation tolerance and long-term storage stability (Sacandé et al., 2000). It is thus probable that much of the variation in the published literature arises due to differences in the maturity of the seeds studied, the chilling sensitivity of neem at mc’s above 10 %, sensitivity to imbibitional damage at lower mc’s, and problems arising from the high oil content of the seed (ca 50 %) which may lead to an underestimation of water activity and unexpected metabolic stress at higher mc’s and temperatures (Sacandé et al., 1998). Although work is ongoing, it is thus becoming increasingly clear that neem seeds have a number of characteristics in common with orthodox types, but that storage is more problematic than for temperate orthodox taxa. Until the storage behaviour of neem becomes more fully understood, a conservative classification of Intermediate? has been adopted | Azadirachta indica var. siamensis: MCS=40-55% ; seeds are desiccation sensitive, minimum safe moisture content is approximately 24% (OuŽdraogo et al., 1999).

Carica papaya | Caricaceae | Carica papaya | No | No | Yes | No | Numerous data are suggestive of intermediate seed storage behaviour e.g. seeds tolerate desiccation to 9.8 % mc, but longevity of seeds stored at 0°C is reduced (Teng & Hor, 1976); viability is lost by 11 % on desiccation from 16 % to 9 % mc, with a further loss of 13 % following 16 hours storage in liquid nitrogen (Chin & Krishnapillay, 1989); seeds tolerate desiccation to 6.5 % mc, but further desiccation to 4.2-5.3 % mc reduces viability by 6-10 % (Ellis et al., 1991b); longevity of dry seeds is reduced when stored at 0°C and -20°C cf. warmer temperatures (Ellis et al., 1991b). Other data are less conclusive but indicate that seeds of the species can tolerate moderate levels of drying, and storage at a range of temperatures e.g. seeds at 10 % mc survive 24 hours in liquid nitrogen (Becwar et al., 1983); no loss in viability after 1 year hermetic storage at 15°C with 8-9.5 % mc (Ellis et al.,1991b), after 3 years at 10±5°C with 40 % r.h. (Pérez et al., 1980), after 6 years at 10°C with either 50 % r.h. or 8 % mc (Bass, 1975); 57 % germination after 29 months storage at 4°-6°C with 8-10 % mc (Singh & Singh, 1981). On the basis of these data it can be recommended that seeds of C. papaya and possibly other species within the genus Carica be stored at 5°C-10°C with 8-10 % mc, or in equilibrium with 40-50 % r.h. Recent studies question the interpretation of C. papaya seeds as intermediate, however. It has been shown that desiccation to between ca 4.5-11.5 % mc induces dormancy within papaya seeds and that this dormancy can be subsequently removed by heat-shocking rehydrated seeds for 4 hours at 36 °C (Wood et al., 2000). The low germination rates observed in the above studies following desiccation to within this mc range may consequently reflect the induction of dormancy, rather than a loss in viability. Similarly, cooling of seeds below certain critical temperature thresholds can also induce dormancy (Chris Wood, pers. com.). In view of these comments, orthodox storage behaviour cannot be ruled out, however, C. papaya is currently categorised as Intermediate? | Seed Information Database (SID) | Intermediate? | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Carica&Species=papaya&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Carica&ftrSpecies=papaya | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Carica+papaya | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Carica&ftrSpecies=papaya |

Cattleya aurantiaca | Orchidaceae | Guarianthe aurantiaca | No | No | Yes | No | There are some similarities of seed storage behaviour between Cattleya aurantiaca and the intermediate arabica coffee. First, seeds of Cattleya aurantiaca tolerate desiccation to moisture contents in equilibrium with 31% r.h., so do seeds of some cultivars of arabica coffee, e.g., Caturra (32% r.h.), Catimor (32% r.h.) (Table 2, Hong & Ellis, 1992c). Second, increase in longevity is observed when reducing seed moisture content from 14% (in equilibrium with 90% r.h.) to 5% (in equilibrium with about 27% r.h.) in Cattleya. Similarly, Cw= 3.5 for arabica coffee was estimated for seed moisture contents between 20% (in equilibrium with 92% r.h.) and 10% (in equilibrium with 50% r.h.) (HBSTGB). Third, cool temperatures (below 5°C) and sub-zero temperatures (-18°C) are more damaging for drier seeds of both species. Fourth, with unlimited number of seedlots and storage environments, optimum air-dry seed storage environments for Cattleya aurantiaca appear to be 5.6-6.5% mc (in equilibrium with 30-50% r.h.) and 5°C (Seaton & Hailes, 1989; Pritchard & Seaton, 1993), Haarer (1962) also found that 5°C with 35-55% r.h. are optimum environments for arabica coffee. Fifth, despite tropical origin, some seedlots of the intermediate arabica coffee are able to survive sub-zero temperatures, e.g., 50% to 80% of seeds of cv. N39 (1987) germinated after 3 years hermetic storage at -18°C with 7.8% mc (in equilibrium with 37% r.h.) (Hong & Ellis, 1992c). Similarly, seeds of Cattleya aurantiaca germinated 96% and 10% after 0.55 and 1 year, respectively, in hermetic storage at -18°C with 5.6% mc (in equilibrium with 31% r.h.) (Seaton % Hailes, 1989; Pritchard & Seaton, 1993). Because of theses similarities, we classify Cattleya aurantiaca in the intermediate seed storage behaviour. | Seed Information Database (SID) | Intermediate | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Cattleya&Species=aurantiaca&StorBehav=0 | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Cattleya&ftrSpecies=aurantiaca | ||

Citrus reticulata | Rutaceae | Citrus reticulata | No | No | Yes | No | MCS= 44% (SSLR) Very low viability (not specified) resulted from drying seeds at 40°C for 24 and 48 hours, after which times seed moisture contents are reduced to 7.5% and 3.7%, respectively, but seeds dried slowly at 5°C to 6.2% mc show 15-30% viability after three months (Mungomery et al., 1966). Partial desiccation tolerance has also been reported by others. For example; Eshuys (cited by King et al., 1981) stated that seeds were relatively tolerant of desiccation; Mallareddy et al. (1977) reported that seeds tolerated desiccation to 10% mc; while viability was lost on desiccation to about 5% mc (Ferreira, cited by King & Roberts, 1979). Similarly, our research has shown that desiccation to 4.6% mc reduced viability by 50%, and that complete loss in viability occurred after 7 months subsequent hermetic storage at -20°C (Hong & Ellis, 1995a). | Seed Information Database (SID) | Intermediate | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Citrus&Species=reticulata&StorBehav=0 | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Citrus&ftrSpecies=reticulata | ||
Citrus sinensis | Rutaceae | Citrus sinensis | No | No | Yes | No | MCS= 52% (SSLR). Desiccation from 45% to 20% mc reduces viability from 71% to 9% (Barton, 1943). Seeds harvested at 50% mc and stored in a refrigerator at 2°-3°C dried slowly to 7.2% mc after 6 months, at which time viability is reduced from 81% to 20% (Bacchi, 1958a). Eshuys (cited by King et al., 1981) stated that seeds were relatively tolerant of desiccation, whereas Ferreira (cited by King & Roberts, 1979) reported complete loss in viability on desiccation to 6% mc. However, seeds maintained for 12 months in storage at 5°C with partially dried seeds (Riley, 1981). Seeds tolerate desiccation to 10.6% mc (in equilibrium with 70% r.h.), but further desiccation reduces viability, about 10% survive desiccation to 4% mc (in equilibrium with 20% r.h.) (SSRL). <20 % survival after drying to 8.7% mc and storage at 5°C for 210 days (Hong et al., 2001). | Seed Information Database (SID) | Intermediate | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Citrus&Species=sinensis&StorBehav=0 | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Citrus&ftrSpecies=sinensis | ||

Cocos nucifera | Arecaceae | Cocos nucifera | No | Yes | No | No | 70% and 44% of excised embryos survived desiccation to 14-15% and 8-9% mc, respectively, and about 40% of excised embryos treated with 10% DMSO plus 3% sucrose followed by partial desiccation (1-2h) survived 12-16 h in liquid nitrogen (Chin & Krishnapillay, 1991).

With this technique, 43% of embryos excised from immature fruits (7-8 months after pollination) survive 1 month's cryostorage, and a few cryopreserved embryos produce whole plants, but 33-93% of embryos excised from mature fruits which have been dried for 4h under a flow hood and then placed in the same medium as above for 11-20 h before rapid freezing in liquid nitrogen produce whole plants with growth delayed by 1-2 months compared with non-frozen embryos (Anon., 1992; Assy-Bah & Engelmann1992; Engelmann et al., 1995b). | Seed Information Database (SID) | Recalcitrant | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Cocos&Species=nucifera&StorBehav=0 | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Cocos+nucifera | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Cocos&ftrSpecies=nucifera | |

Coffea arabica | Rubiaceae | Coffea arabica | No | No | Yes | No | MCS= 48%; Bacchi (1958a) reported that, between 10% and 20% mc, seed longevity was inversely proportional to moisture content. Bendana (1962) observed no detrimental effects when seeds dried to 5% mc, whereas Bacchi (1955, 1956) and Huxley (1964a) reported a loss in germination following desiccation below 8% mc; and greater loss in viability following storage at 2°C to 5°C, and much more loss at sub-zero temperatures than at warmer temperatures were reported (Wellman & Toole, 1960; Bendana, 1962; Huxley, 1964a; Vossen, 1979). LSMC= 8%, unfreezable mc= 24%, viability was completely lost within 24 hours at -196°C with 8% mc (Becwar et al., 1983). Results of investigations on desiccation tolerance of 17 seed lots representing nine cultivars received from three continents showed that arabica coffee seeds tolerated desiccation to between 7% and 12% mc, i.e., in equilibrium with about 40-55% r.h., but further desiccation reduced germination in all seed lots; moreover, viability was lost rapidly at cool (5°C and 0°C) and sub-zero temperatures (-20°C), and at low moisture contents (Ellis, Hong & Roberts, 1990b, 1991a; Hong, 1992c). The optimum air-dry storage environments for the maintenance of seed viability is ambient temperature with 10% mc (Bacchi, 1958b), 10°C with 50% r.h. (about 10% mc) (Wellman & Toole, 1960), 9°C with 50% r.h. (Bendana, 1962), 5°C with 35-55% r.h. (about 7.5-11% mc) (Haarer, 1962), 10°C with 10-11% mc (Hong & Ellis, 1992c). Excised embryos tolerated desiccation to16.4% mc, viability was reduced to 56% and 8% on desiccation to 8.4% and 7.7% mc respecitvely; no loss in viability after 1 hour of cryostorage with excised embryos at 8.4% mc but no excised embryos at 7.7% mc survived 1 hour in liquid nitrogen (Abdelnour-Esquivel et al., 1992b). seed is partially desiccation tolerant and temperature sensitive, lowest safe moisture content of 10 % at 15°C, but 12 % at -20°C (Eira et al., 1999). There is evidence that some seed lots of cultivar Caturra can be maintained with high viability for at least 10.5 yrs at -20ºC and 8.4 % mc. At higher and lower mc's reduced viability was observed (Hong and Ellis, 2002). The authors go on to suggest that this mc (equivalent to equilibrating to 43 % RH at 20ºC) represents a narrow window within which medium-term storage of seed is possible. | Seed Information Database (SID) | Intermediate | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Coffea&Species=arabica&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Coffea&ftrSpecies=arabica | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Coffea+arabica | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Coffea&ftrSpecies=arabica |

Desiccation to 11.3% mc reduces viability by 22% and only 2% survive further desiccation to 7% mc, survival in the best hermetic storage environment of 15°C with 11.3% mc is poor with 4% viability after 12months, viability is lost more rapidly during storage the lower the temperature below 15°C and the lower the moisture contents below 11.3% (Hong & Ellis, 1995a). 100% of excised embryos survived desiccation to 29% mc, but only 42% of those excised embryos survived subsequent cryostorage for 1 hour in liquid nitrogen; seed is partially desiccation tolerant and temperature sensitive, lowest safe moisture content of 10 % at 15°C, but 13 % at -20°C (Eira et al., 1999) (Abdelnour- Esquivel et al.,1992b). | Seed Information Database (SID) | Intermediate | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Coffea&Species=canephora&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Coffea&ftrSpecies=canephora | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Coffea+canephora | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Coffea&ftrSpecies=canephora |

Elaeis guineensis | Arecaceae | Elaeis guineensis | No | No | Yes | No | MCS= 23% (Chin et al., 1984) Seed storage behaviour has been reviewed (Ellis, Hong & Roberts, 1985b). Storage temperature of 5°C is damaging to seed viability in moist storage (Mok & Hor, 1977). Kernels are safely dried to 4.4% mc when set to germinate in vitro, however hermetic storage of intact kernels at -18°C or -196°C with moisture contents between 20.9% and 4.4% results in complete loss in viability; excised embryos are safely dried to 19.9% mc, but further desiccation to 10.4% mc reduces viability by about 13%, no loss in viability after 8 months subsequent storage in liquid nitrogen (Grout et al., 1983). No loss in viability occurs after 4 months hermetic storage at either 10°C or 30°C with 19.4 - 5.2% mc (Roberts et al., 1984). 50-70% of excised embryos survive desiccation to 10.4% mc by slow drying and no loss in viability in subsequent cryostorage overnight (Hor et al., 1994). Similar results of cryostorage of excised embryos have been reported by Engelmann et al. (1995a; 1995b). Seeds tolerate desiccation to 10-6% mc, depending on seed lot, no loss in viability after 12 months subsequent hermetic storage at 15°C, but complete loss in viability occurs at 0°C, and -20°C (Ellis et al., 1991d). | Seed Information Database (SID) | Intermediate | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Elaeis&Species=guineensis&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Elaeis&ftrSpecies=guineensis | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Elaeis+guineensis | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Elaeis&ftrSpecies=guineensis |

Khaya senegalensis | Meliaceae | Khaya senegalensis | No | No | Yes | No | Several studies suggest that the species is desiccation tolerant, but chilling sensitive: viability is maintained in hermetic storage for 2 years at 2.2 % mc and 0°C, but is rapidly lost at the lower temperature of -20°C (Hong and Ellis, 1998); at 20°C seeds tolerate desiccation to 5.7% mc (in equilibrium with 54.4% r.h.) and show little loss of viability on further desiccation to 2.1% mc (in equilibrium with 11.8% r.h.), but complete loss of viability occurs following 24 months hermetic storage at 10°C, 0°C and -20°C (at 10% mc; SSLR). For seeds at lower mc's of between 2.2 % and 5.6%, it appears that 0°C is the optimal storage temperature, whilst -20°C is damaging (SSLR). Other studies are inconclusive, or indicative of orthodox storage behaviour: seeds tolerate desiccation to 6% mc and 81% germinate following 3 years subsequent hermetic storage at 2°C, Cw= 2.15 (Tompsett, 1994); Tompsett (1994) classifies the species as orthodox; viability is maintained after 12 months storage at 25ºC, 3-5ºC and -18ºC and <3 % mc (IPGRI/DFSC, 1999). A tentative classification of Intermediate? has thus been assigned. | Seed Information Database (SID) | Intermediate? | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Khaya&Species=senegalensis&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Khaya&ftrSpecies=senegalensis | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Khaya+senegalensis | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Khaya&ftrSpecies=senegalensis |

Chilling damage occurs at temperatures below 15°C; for example, no seeds germinate after 4 hours moist storage at 4°C (Sasaki, 1980). Seeds are desiccation sensitive with minimum safe moisture contents of 32 % (Malaysia) and 21 % (Indonesia), mc at shedding = 42-50 % (Ouédraogo et al., 1999); viability lost when dried below 20 % mc (fresh seeds) and 30 % mc (in seeds tested 3 weeks after harvest), best conditions for storage up to 14 weeks were 42 % mc and 16ºC or 25ºC, but for storage beyond 14 weeks seeds dried to 32 % mc shopwed greater viability at both temperatures (IPGRI/DFSC, 1999). Comment: This species has been classified as recalcitrant (Hofmann & Steiner, 1989). Sasaki (1980) reported that mature seeds contain 31-33% mc when harvested from the trees, at which mc viability is 100%.

COMMENT: This species has been classified as recalcitrant (King & Roberts, 1979; Yap, 1986). Desiccation sensitivity reported by Sasaki (1980) was from desiccation of immature seeds; for example, viability was maintained 100% when immature seeds (mc not reported) were dried at 25°C to 49% mc, viability was reduced to 40% and 10% on desiccation to 28% and 13% mc, respectively (Sasaki, 1980), while mature seeds harvested from the tree on September had 34-35% mc with 100% viability (Sasaki, 1980). If maturation drying occurs to this low level, this species may not show recalcitrant seed storage behaviour.

Comment: This species has been classified as recalcitrant (Yap, 1986; Tompsett, 1992). However, based on low seed mc of mature seeds harvested from the tree at mid February (MCS= 32%) at which viability is high (96%) (Tamari, 1976)), seeds of this species might possibly not show recalcitrant seed storage behaviour. Further investigations with mature seeds are needed. | Seed Information Database (SID) | Recalcitrant | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Shorea&Species=parvifolia&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Shorea&ftrSpecies=parvifolia | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Shorea+parvifolia | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Shorea&ftrSpecies=parvifolia |
Shorea platyclados | Dipterocarpaceae | Shorea platyclados | No | No | Yes | No | This species can be classified into intermediate seed storage behaviour because of low seed mc at harvest and (MCS=37%) and desiccation tolerance (LSMC=11%). Since the species is adapted to high altitude, it is suggested that seeds can be safely stored at 10-15°C. More work is needed to determine optimum air-dry seed storage environments. | Seed Information Database (SID) | Recalcitrant? | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Shorea&Species=platyclados&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Shorea&ftrSpecies=platyclados | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Shorea+platyclados | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Shorea&ftrSpecies=platyclados |

COMMENT: More investigations with mature fruits are needed. Based on ecological adaptation (savanna and dry hills) and small seeds, this species might be expected not to show recalcitrant seed storage behaviour. Furthermore, about 10% of seeds survive desiccation to 9.6% mc (Nautiyal & Purohit, 1985c). Although this species has been classified as recalcitrant, further studies would be worthwhile. | Seed Information Database (SID) | Recalcitrant | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Shorea&Species=robusta&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Shorea&ftrSpecies=robusta | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Shorea+robusta | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Shorea&ftrSpecies=robusta |

Warburgia salutaris | Canellaceae | Warburgia salutaris | No | No | Yes | No | (The fruit is a berry containing about 5 seeds in a pulpy medium). This species is classified as recalcitrant (Albrecht, 1993), however viability can be maintained for 6 months at cool temperatures with dry seeds (Shehaghilo, pers. com.), storability is intermediate between orthodox and recalcitrant (Msanga, per. com.). For short term, seeds can be stored in moist saw-dust at 3°C (Albrecht, 1993). Seeds tolerate drying to 7-16 % mc (Ouédraogo et al., 1999); survival in conventional storage appears to be short-term (IPGRI/DFSC, 2001b), but rapidly dried seeds can be successfully cryo-preserved (Kioko et al., 2000). Comment: Based on fruit structure (many seeded berry), seed size (TSW= 100g)and natural habitats (from dry savannas of Southern Africa to lowland rainforests of E. Africa) seeds of this species may not be recalcitrant. More investigations are needed. | Seed Information Database (SID) | Intermediate? | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Warburgia&Species=salutaris&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Warburgia&ftrSpecies=salutaris | https://www.bgci.org/resources/bgci-databases/globaltree-portal/species-search/?species=Warburgia+salutaris | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Warburgia&ftrSpecies=salutaris |

Zizania palustris | Poaceae | Zizania palustris | No | No | Yes | No | This species has been reported to lose viability when stored dry (eg., Duvel, 1906; Muenscher, 1936) or when desiccated at 15°C, for example, ELSMC= 45-50% or at a water potential of -2, -3 MPa and no excised embryos survived further desiccation to 10% mc or -60 MPa (Probert & Brierley, 1989; Probert & Longley, 1989). Earlier classification as recalcitrant may relate to its pronounced dormancy (Ellis et al,, 1985b; Kovach and Bradford, 1992a) or the desiccation sensitivity of seeds when dried at temperatures <25°C (Kovach & Bradford, 1992b) or through the use of immature seeds (Vertucci et al., 1995). However, wild rice seeds survived desiccation to seed and embryonic axis moisture contents as low as 6-8% if dehydration occurred at temperatures >25°C (Kovach & Bradford, 1992b), or between 40°C and 70°C (Huang, 1978). Seeds tolerated desiccation to 9-10% embryo mc, but no embryos survived desiccation below 5% mc (Still et al., 1994). The properties of water (i.e., the freezing and melting behaviour of water in embryos at different water contents determined by differential scanning calorimetry methods) in embryos changed during seed development and maturation and were similar to those of water in embryos of desiccation-tolerant seeds, but the seeds never achieved the orthodox condition and were analogous to that of seeds with intermediate seed storage behaviour (Vertucci et al., 1994b). No loss in viability was observed with seeds dried to 11.5% mc at 22°C and subsequently stored at -2°C or 2°C for 6 months (Oelke & Stanwood, 1988), but only 50% of seeds survived further drying to 9% mc and 9 months subsequent storage at 3°C (Oelke et al., 1990). A loss in viability of about 11-15% was observed after 15-16 months storage at -18°C with 5.4-6.8% mc for embryonic axes (Berjak et al., 1994). Embryos from mature seeds survived 2 hours' exposure to temperatures as low as -50°C while those from immature seeds survived only to -18°C and long-term preservation is said to be possible at -20°C provided optimum embryo moisture contents are determined in relation to the maturity status of the embryos (Vertucci et al., 1995). Note that some of the results summarised above are for seeds first stored in water (see Part I, Section 6.4). | Seed Information Database (SID) | Intermediate | https://data.kew.org/sid/SidServlet?Clade=&Order=&Family=&APG=off&Genus=Zizania&Species=palustris&StorBehav=0 | https://tools.bgci.org/threat_search.php?action=Find&ftrFamily=&ftrGenus=Zizania&ftrSpecies=palustris | https://tools.bgci.org/plant_search.php?action=Find&lang=eng&ftrGenus=Zizania&ftrSpecies=palustris | |
