Characteristics

Plants 300-500(-700) mm high. Corm ± bell-shaped, with flat base, ± 10 mm diam.; tunics of ± woody overlapping layers, fragmenting below into segments with minutely fringed margins. Stem simple or rarely with branch from near base, sheathed at base by membranous, pale or rarely brown cataphyll. Leaves usually 5, lower 2 or 3 basal and with long blades, linear, straight, often trailing, reaching to ± base of spike, wide, upper 2 leaves sheathing lower 2/3 of stem. Spike 3-to 6(9)-flowered, ± secund; bracts green, often flushed red distally, 12-25 mm long, outer with margins united around axis for 1-2 mm. Flowers nodding, ± white or creamy white, outer tepals brown to purplish outside; perianth tube 18-25 mm long, curved in distal half and becoming pendent; tepals subequal, narrowly ovate-elliptic, 14-18 x 5-6 mm, spreading. Filaments evidently unilateral, ± pendent, ± 6 mm long; anthers mostly 8-10 mm long, decumbent, purple-brown; pollen brown. Style branches 10-12 mm long, pendent, reaching ± to anther tips on closed flower. Capsules ovoid-oblong, 10-12 x 4 mm, enclosed in bracts, splitting in upper 1/3. Seeds unknown.
