Plants 150-350 mm high. Corm up to 30 mm diam.; tunics of coarse, wiry, black fibres. Stem flexuose, several-branched from upper nodes, fewer-branched in years of low rainfall, upper nodes sometimes with ± sheathing leaves, usually with expanded leafy tips. Foliage leaves 3 to several, lowermost ± basal (or inserted shortly above ground), up to 350 mm long, channelled, 8-20 mm wide, margins straight or slightly undulate. Rhipidial spathes with dry attenuate apices, inner 40-60 mm long, outer 2/3 as long. Flowers fugaceous, half nodding, pale yellow, tepal limbs with darker yellow nectar guides as bases often edged grey or green, spreading, usually twisted through 90º; outer tepals 18-28 x 9-10 mm, narrowly obovate, to pandurate, claws poorly defined, ± 1 mm long, ascending, inner tepals slightly smaller. Filaments 4-5 mm long, united below in a slender, smooth column, free and diverging in upper 0.5-1.0 mm; anthers ± 2 mm long, strongly arched against style branches, yellow; pollen yellow. Ovary ± cylindric, 7-10 mm long, exserted; style branches diverging, ± 2 mm long, flattened, nearly horizontal, stigma lobes upright, appressed to crests, stigmatic laterally, crests arching inward to ± horizontal, ± 2 mm long.
