Characteristics

Bulb solitary, globose to ovoid, 0.0-7.5 mm diam., with outer tunics felt-like and light brown, whitish within; neck stout, up to 50 mm long. Leaves absent at anthesis, (2-)3-4, arranged in a fan, erect, more or less falcate, broadening towards an obtuse to truncate apex, 45-100 x 9-20 mm, leathery, somewhat sticky when young, glabrous, bright green on both surfaces, usually flushed with red towards the base, subtended by a subterranean amplexicaul cataphyll; seedling glabrous. Inflorescence clustered, 10-30 mm across; scape straight to slightly flexuose, 80-150 mm long, 1-2 mm diam., green to wine-red, persisting throughout fruiting then collapsing; spathe valves lanceolate, 15-18 x 2-4 mm; bracteoles up to 12 mm long. Flowers 5-8, ascending, campanulate, glistening white, sometimes faintly flushed with pink along the median dorsal surface, remaining unchanged or becoming completely flushed with pink with age, scented; pedicels straight, 8-25 mm long, green. Tepals free to the base, spreading slightly, ovate-lanceolate, 5-8 x 3-4 mm, somewhat channelled. Stamens longer than the tepals, spreading slightly; filaments separate, up to 9 mm long, shortly adnate to the swollen style base, expanding upwards in the proximal half and terminating midway in a prominent, irregularly toothed transverse ridge, abruptly narrowed and subulate distally; anthers dorsifixed, about 2.5 mm long and deep pink before opening; pollen cream-coloured. Ovary with up to 2-4 ovules per locule. Style up to 7.5 mm long, with the proximal half enlarged into a 2.5 mm broad, slightly fluted disc with a raised irregularly toothed upper rim, abruptly narrowed into a slender terete column in the distal half, with nectar collecting in three droplets between the base and inner filaments. Seeds 3 mm diam.
