Leaves several, linear to sword-shaped, (4-)6-12 mm wide, basal longest, with visible main vein. Rhipidia 2-flowered; spathes green with membranous margins, inner 45-65 mm long, outer ± half as long, usually entirely sheathing.

Filaments united in smooth column ± 6 mm long, free in upper 3 mm; anthers ± 3 mm long, thecae parallel, shortly apiculate; pollen orange. Ovary ellipsoid, without beak, included in spathes, 12-20 mm long; style branches ± 4 mm long, forked in upper half, divided into diverging arms; 4-5 mm long, prominently fringed; stigmas terminal on style arms.
