Characteristics

A geophyte 120-300 mm tall when in flower. Tuber a turnip-shaped or elongated, sometimes moniliform root 30-50 mm long, 12-30 mm in diameter. Leaves simple, green, petiolate; lamina lanceolate, 70-135 x 20-40 mm, base attenuate, apex acuminate, margin entire; young leaves adaxially pilose and abaxially pilose interspersed with stiff hairs or sometimes bristles, margins with appressed bristles; petiole 20-80 mm long, 2-3 mm in diameter, rigid, erect, pilose with short hairs interspersed with bristles; stipules subulate, adnate to petioles for one third to one half their length, 27-35 mm long, 1-3 mm wide, ciliate. Inflorescence: scape 30-110 mm long, 3-5 mm in diameter, branched, bearing (2)3-7 pseudo-umbellets with 14-31(-35) flowers each; peduncles 30-100 mm long, 1.5-3.0 mm in diameter, densely hirsute interspersed with long glandular hairs and very long non-glandular hairs; bracts subulate, 7-14 mm long, 1.0-1.5 mm wide, adaxially velutinous, abaxially densely hirsute interspersed with long glandular hairs. Pedicel ±0.5 mm long. Hypanthium 40-60 mm long, 5.5-6.5 times as long as sepals, green, densely hirsute interspersed with long glandular hairs. Sepals 5, green, narrowly triangular, 7-11 x 1.0-2.5 mm, apex acuminate, patent, with membranous margin, indumentum abaxially as on hypanthium. Petals 5, pale yellow, patent during anthesis; posterior two minutely dotted with wine-red spots in central part, ligulate to narrowly spathulate, 13-20 x 3.0-3.5 mm, length/width ratio 5.5-6.5, base narrowly cuneate, apex truncate to emarginate; anterior three ligulate, 11-18 x 2-3 mm, base attenuate, apex truncate to emarginate. Stamens: staminal column 1.5-3.0 mm long, white, papillate; perfect stamens 5, white, initially straight, bending downwards during senescence, posterior one 5-7 mm long, lateral two 6-8 mm long, anterior two 7-9 mm long, ± as long as sepals; staminodes 2-4 mm long; anthers pale pink, 1.0-1.5 mm long, pollen pale yellow. Gynoecium: ovary 3.0-5.5 mm long; style 1.5-5.0 mm long, dark pink; stigma branches 1-2 mm long, pink. Fruit: bases of mericarps 6-7 mm long, with glandular hairs, tails 32-35 mm long.
