Characteristics

Plants 150-300 mm high. Corm ± ellipsoid, 6-10 mm diam., corms of previous seasons persistent and accumulating below current corm; tunics brown, woody to soft-papery, concentric but sometimes imbricate by displacement especially when soft, fragmenting irregularly from base and apex, outer layers sometimes ± fibrous, extending upward in a collar with decaying leaf bases. Stem erect, smooth, simple or 1-or 2-branched, bearing 2 or 3 dry sheathing bracts below spike. Leaves 3 to 5, lower 2 to 4 leaves basal, terete or nearly so, margins and main vein much enlarged, thus narrowly 4-grooved, ± 1/2 to as long as stem, uppermost cauline, short, partly to entirely sheathing. Spike 1-flowered on main axis and lateral branches; bracts drying near apex, (12-)16-30 mm long, inner as long, or slightly shorter than outer. Flowers salver-shaped, pink to purple; perianth tube (8-)17-20 mm long, cylindric, widening gradually near apex, reaching almost to tips of bracts or shortly exserted; tepals oblanceolate-elliptic, 25-30 x ± 11 mm. Filaments equal, 13-20 mm long; anthers 10-12 mm long, brown; pollen brown. Style eccentric, dividing opposite or beyond anther tips.
