Characteristics

Bulb solitary, subglobose, 5-14 mm diam., with thinly fibrous greyish-brown outer tunics, whitish and fleshy within; neck slender, up to 75 mm long. Leaves well developed or rarely absent at anthesis, 4-6, with only 1-4 exserted at a time, spreading, straight or curled, filiform, hemiterete, 30-150 x 1 mm, glabrous, shiny green, subtended by a non-amplexicaul prophyll; cataphyll lacking; seedling glabrous. Inflorescence sparse, up to 65 mm across; scape slender, 25-210 mm long, 0.5-1.0 mm diam., spirally twisted and reddish brown basally, otherwise suberect, stiff and green; persisting and remaining green for several months after seed-release; spathe valves linear-lanceolate, 5-20 x 1-2 mm; bracteoles not visible. Flowers 1-5, slightly spreading, funnel-shaped, pure white or flushed with pink abaxially, occasionally greenish yellow in the throat, buff-coloured when withered, sometimes scented; with the innermost flowers of the cymes often aborting; pedicels ascending, filiform, 5-50 mm long, green. Tepals connate basally into a tube 3-4 mm long, expanding gradually upwards to 2.5-3.0 mm across at the throat, spreading, oblong-lanceolate, 7-14 x 2.0-3.5 mm. Stamens 6, suberect, only shortly exserted from the perigone tube; filaments separate, 3-5 mm long, decurrent for about 2-3 mm from the middle to the base of the perigone tube, with the inner whorl basally adnate to the style for up to 1 mm, subulate; anthers subcentrifixed, 2 mm long and pale yellow before opening; pollen cream-coloured. Ovary 1.5-2.0 mm diam., green, with 1-6 ovules per locule. Style up to 5 mm long, only shortly exserted beyond the perigone tube, triquetrous, stout, with nectar collecting in the sinuses between the style and inner filaments; stigma trifid. Seeds 3-4 mm diam., more or less ovoid, obtusely hooked, covered with stomata.
