Description:
Evergreen geophyte. Corm depressed-globose, axillary in origin, past season's corms not resorbed; tunics coarsely fibrous. Cataphylls 2 or 3, leathery and brownish. Stem aerial, erect, repeatedly branched above, 2-angled or narrowly winged below, inflorescence axis often sparsely warty. Leaves several, unifacial, leathery and closely fibrotic, without evident main vein, lowermost leaf longest, linear, twisted, sometimes trailing, with 3 or 4 progressively smaller ± sheathing cauline leaves, dry and brown; margins simple, without vascular bundle, epidermis unspecialized. Inflorescence panicle-like, much-branched, with a solitary, sessile flower terminal on each axis; bracts leathery, green with reddish-brown margins, glutinous inside, inner ± as long as outer and similar in texture, clasping ovary, multinerved and acute. Flowers actinomorphic, long-lived, cup-shaped, orange, unscented, not closing at night, with traces of nectar from septal nectaries; perianth tube short, funnel-shaped; tepals subequal, spreading, obovate. Stamens symmetrically arranged; filaments inserted just below mouth of perianth tube; anthers suberect or apically incurved, yellow. Ovary covered in mucilage from bracts; style filiform, 3-branched distally, branches slender, bifid or divided apically for 1/4–1/3 their length, longitudinally folded. Capsules subglobose, woody. Seeds 1–3 per locule, large, angular with chalazal crest, smooth and shiny, testal cells finely reticulate-foveate. Pollen monosulcate-operculate, operculum 2-banded, exine perforate-scabrate. Basic chromosome number x = 20.
