Characteristics

Plants 80-200 mm high. Corms deep-seated, 15-25 mm diam., tunics of coarsely netted fibres, extending into neck to 50 mm long, pale brown. Basal leaves ± 10-20, erect, filiform to linear, (40-) 50-100 x 0.5-3.0 mm, attenuate, leathery, bright green, glabrous. Inflorescence a highly congested, simple raceme such that flowers apparently solitary among leaves; pedicels suberect, (80-) 100-200 mm long; bracteoles either subbasal or inserted in upper half. Flowers enantiomorphic, facing outwards, white or pale pink or pale yellow, fragrant; tepals spreading, cucculate, outer elliptic, 12-20 x 5-7 mm, recurved-apiculate, inner ovate, 12-20 x 7-12 (-15) mm, acute, narrowed basally or shortly clawed, claw to 1 mm long. Stamens weakly dimorphic or sub-monomorphic, 5 + 1; filaments of posterior cluster 3-5 mm long, connate only at extreme base, awl-shaped, white, anthers 3.5-5.5 mm long, yellow, sometimes marked with black spot on upper surface near base, soemtimes adherent; anterior stamen with filament deflexed laterally, 3-4 mm long, awl-shaped, connate to upper cluster at extreme base, anther 4-6 mm long, yellow. Ovary half inferior; style laterally deflexed opposite lower stamen, 7-9 mm long, not extending beyond lower anther. Capsules erect, ellipsoid, 13-15 x 7-8 mm, 3-lobed. Seeds ovoid, ± 2 mm diam., rugulose.
More
Cormous geophyte, 120-250 mm tall. Leaves filiform-terete. Flowers in a contracted raceme on long, suberect pedicels up to ± 200 mm long, white or yellow to pale pink, fragrant, tepals 12-20 mm; anthers yellow, with or without dark spot, 5 upper and 1 larger lower, filaments free; strongly enantiostylous.
A bulb or corm plant. It grows 8-20 cm tall. The corm is 15-25 mm across. There are 10-20 leaves at the base. They are narrow and 5-10 cm long by 0.5-3 mm wide. The flowers are very close together on a long stalk. The fruit is an erect capsule 13-15 mm long by 7-8 mm wide and it has 3 lobes.
Cormous geophyte, 12-25 cm. Leaves filiform-terete. Flowers enantiostylous, in a congested raceme thus apparently solitary on long, erect peduncles, white to pink or yellow, fragrant, with 5 upper and 1 larger lower stamen, filaments free nearly to base.
