Leaves variable, green or glaucous, spreading at ground level or arcuate from a short stemlike base, deeply canaliculate, from slightly to very strongly undulate, 80 cm long, or longer, 2-16 cm broad, margins with a narrow cartilaginous border and sparsely to fairly densely ciliate with short to about 1 mm long cartilaginous hairs. Peduncle arcuate-erect or erect and arcuate at the base only, varying in length, 18-90 cm long, 1.5-3 cm broad and 0.6-1.7 cm thick. Spathe-valves 6-10 cm long, 2-4 cm broad just above the base, rather thick, becoming parchmentlike but not very thin, eventually partly reflexed; bracteoles narrow linear.

Perianth with a long or short tube, the segments conniving in a wide trumpet shape with the apical portion recurved; tube 3-11 cm long, cernuous; segments about 7-11 cm long, white with a distinct rose coloured keel, rarely, in some areas, the whole segment rosy with a deep carmine keel; apical peak on outer segments about 5 mm long, on obtuse inner segments, short and broad. Stamens declinate, filaments usually white; anthers black. Style white with the apical portion red.
