Leaves 3 to 9, all evidently basal, 4-winged, lateral ribs reduced, median ribs marginally winged and glabrous or ciliate and sometimes also sparsely villous on margins, sometimes crisped, 2-5 mm wide. Peduncles up to 5, angled, glabrous or pilose on angles, recurved or suberect in fruit; outer bracts green or submembranous below, with narrow, usually brown-flecked, membranous margins, 10-18 mm long, closely ribbed (± 8 veins/mm), inner bracts with wide, brown-flecked membranous margins. Flowers pale yellow (rarely white), sometimes with golden-yellow cup, often with diffuse brownish or greenish transverse band in throat, rarely with brown blotches in throat, outer tepals greenish yellow on reverse; perianth tube funnel-shaped, 4-5 mm long; tepals oblanceolate or elliptic, 12-25 x 4-8 mm. Filaments 5-6 mm long, pilose basally or subglabrous, yellow; anthers 3-5, yellow. Style dividing opposite anthers. Capsules subglobose to oblong, up to 10 mm long.
