Corm laterally compressed, (7)9.5(14) mm in diameter, with a basal crest ascending by both sides of the corm; tunics brown, brightless, coriaceous, with marked nerves descending down the tunics to the renovation bud. Cataphyll membranous, white, papery in texture at senescence. Leaves distichous, ovate-lanceolate, 40-60(200 mm in cultivation) x (5)15(25) mm, amplexicaule, glaucous, apex acute, margin with papillaes more frequently near the apex. Hypsophylls elliptic with similar texture to nomophylls, (25)42(55) x (15)22(26) mm, glaucous, apex acute, margin with a narrow white wing. Flowers subsessile, 1-2 per corm, disagreeably scented; perianth 20-25 mm long; tepal lamina lanceolate, recurved, apex obtuse, (10)13.4(17) x (7)8.3(12) mm, green, with auricules semi-transparent embrancing only the filament sides; claw (4.5)7.3(10) mm long, white with purple nervations. Stamens semi-exserted; filaments (6)8.6(11.5) mm long, purple; anthers lanceolate, (5)7.3(10) x (2)2.5(3.5) mm, bluish-purple; nectary circumbasal, purple, two fold wider than the filament at the center. Ovary oblong (6)7.1(8) mm long; style (7)8(9) mm long; stigma papilose, capitate, purplish. Capsule globose, indehiscent, (9)11.9(16) x (7)11.1(17) mm. Seeds globose, (1)1.35(1.7) mm in diameter, testa dark brown and rough, without a developed raphe. Few idioblasts on leaves, but abundant in tepals and capsule, identifiable in senescence as densely distributed red dots.
