Tuberous-rooted perennial, tuber as long as stem or longer. Stem 300-1060 mm tall, medium to very stout, simple or branched at the base, frequently with more than one stem arising from the same rootstock, ± glabrous to scabrous or pubescent, rarely subtomentose, hairs usually bifarious. Leaves ascending-spreading; petiole 3-12(-15) mm long; blade 32-127(-140) x 10-58(-65) mm, narrowly oblong, narrowly oblong-ovate or narrowly elliptic to elliptic, ovate or broadly oblong, rarely suborbicular, margins scabrous or pubescent, surfaces ± glabrous to scabrous or pubescent. Inflorescence umbellate, 3-6(-10)-flowered, sessile but the lowermost usually pedunculate, at nodes and terminal; peduncules up to 35 mm long, ± glabrous to scabrous or pubescent. Bracts 2-12 mm long, narrowly linear, narrowly lanceolate or lanceolate, ovate, acuminate, pubescent or scabrous below, deciduous. Pedicels 15-35(-45) mm long, ± glabrous to scabrous or pubescent. Sepals 6.0-7.0 x 2.8-8.5 mm, lanceolate or narrowly ovate, rarely elliptic or oblong, acute or acute-acuminate, glabrous or rarely puberulous near the apex above, pubescent below. Corolla 11-24(-28) mm long, lobed almost to the base, dirty greenish-whit hairs giving the surface a velvet-like appearance above, puberulous to pubescent below; lobes 8-22(26) x 7-14 mm, reflexed-spreading, elliptic, oblong or ovate, rarely narrowly ovate-lanceolate, apex acute or obtuse and usually notched, margins revolute. Corona lobes 2.0-7.5 mm long, 2.0-6.2 mm high at the base, lanceolate, ovate or oblong, with a pair of contiguous fleshy keels 0.5-3.7 mm high, 1.0-7.0 mm long, obtuse, subdeltoid, usually extending to, or almost to, the apex, rarely slightly beyond the apex, which if prolonged beyond the keels is obtuse, recurved, horizontal or upcurved; sometimes the keels are very reduced and the lobes are small, spreading, scarcely projecting beyond the anther wings, recurved at the shortly pointed apex with the reduced keels forming a cut-like groove along the upper face, keels and corona lobes whitish-dull green often tinted with purple. Anther wings 3.0-8.6 mm long, slightly oblique, outer edge more or less straight or slightly concave with basal angle curved outwards; appendages 2.0-4.5 mm long, narrowly ovate or oblong to broadly ovate or suborbicular, tip acute or obtuse, erect at the base and then curved over and covering the style apex. Follicles 80-100 mm long, globe-shaped, weakly ridged, green with mauve markings.
