Stem several-branched, slightly flexed above sheaths of foliage and sheathing leaves, these attenuate, 35-60 mm long. Foliage leaf solitary, usually inserted well above ground, linear, channelled, exceeding stem and trailing distally, 9-13 mm wide. Rhipidial spathes attenuate, inner 55-80 mm long, outer 1/2-2/3 as long. Flowers long-lived, salmon-pink or yellow with yellow cup, all tepal limbs with deep yellow nectar guide at bases, ± spreading, tepal claws diverging, forming wide cup ± 12 mm deep including filaments and bases of anthers; outer tepals ± oblong to obovoid, 35-40 x 13-20 mm, claws up to 14 mm long, smooth or minutely papillate in lower part, inner tepals slightly smaller than inner. Filaments 7-8 mm long, united in a column smooth to sparsely papillate-pubescent in lower half, widest at base, tapering slightly to apex; anthers 8-11 mm long, contiguous for 3 mm, slightly diverging distally, yellow; pollen yellow. Ovary cylindric, 17-20 mm long; style branches slightly diverging, up to 7 mm long, stigmas bilobed, curved upward above apex of anthers, crests ± 1 mm long, erect, triangular.
