Habit
Deciduous geophyte 120-300 mm tall when in flower, tuber turnip-shaped or elongated, sometimes moniliform.

Leaves
Simple, lamina lanceolate, base attenuate, apex acuminate, margin entire, 70-135 x 20-40 mm, young leaves adaxially pilose and abaxially pilose interspersed with stiff hairs or sometimes bristles, margins with appressed bristles. Petiole 20-80 mm long, rigid, erect, pilose with short hairs interspersed with bristles, stipules subulate, adnate to petioles for one third to one half their length.

Inflorescence
Scape, branched, bearing (2-)3-7 pseudo-umbellets, each 14-31(-35)-flowered. Pedicel cca. 0.5 mm.

Sepals
5, narrowly triangular, apices acuminate, 7-11 x 1-2.5 mm, patent, green with membraneous margins, indumentum abaxially as on hypanthium. Hypanthium 40-60 mm, densley hirsute interspersed with long glandular hairs.

Petals
5, pale yellow, patent during anthesis, posterior two minutely dotted with wine-red spots in the central part, ligulate to narrowly spathulate, bases narrowly cuneate, apices truncate to emarginate, 13-20 x 3-3.5 mm, anterior three ligulate, bases attenuate, apices truncate to emarginate, 11-18 x 2-3 mm.

Stamens
5 fertile, initially straight, bending downwards during senescence, posterior one 5-7 mm, lateral 6-8 mm, anterior two 7-9 mm long, white, pollen pale yellow.
