A geophyte 80-250(-280) mm tall when in flower. Tuber: a turnip-shaped or elongated, sometimes moniliform root, 15-40 mm long and 10-25 mm in diameter. Leaves green, petiolate; lamina elliptic, 25-95(-140) mm long, regularly pinnate; pinnae irregularly lobate to pinnatisect or laciniate, 10-30 x 6-20 mm, adaxially and abaxially hirsute with long appressed stiff hairs; petiole 15-60(-90) mm long and 1-2 mm in diameter, rigid, erect, hirsute with appressed stiff hairs interspersed with bristle-like hairs and very short glandular hairs; stipules subulate, adnate to petioles with apices free, 10-22 mm long and ±1 mm wide, ciliate. Inflorescence: scape 20-160(-200) mm long, branched, bearing (2-)3-5(-6) pseudo-umbellets with 7-14(-18) flowers each; peduncles 40-120 mm long, 1-3 mm in diameter, green, densely covered with appressed curly hairs interspersed with long glandular hairs; bracts subulate, 2-5 x 1 mm, abaxially hirsute with distally appressed hairs. Pedicel ±0.5 mm long. Hypanthium 8-16 mm long, 1-1.8 times the length of the sepals, reddish brown, densely hirsute with appressed hairs interspersed with long glandular hairs. Sepals 5, lanceolate, apices acute, 6-10 mm long, 2-1.5 mm wide, recurved, green, indumentum abaxially as on hypanthium. Petals 5, white, patent during anthesis; posterior two with dark red feather-like markings, ligulate to spathulate, slightly curved, bases cuneate, apices obtuse, rounded or emarginate. recurved during anthesis, 5-8.5 x 1.5-3 mm, length/width ratio 3-4; anterior three spathulate, bases attenuate, apices rounded, 4.5-8 x 1.5-2 mm. Stamens: staminal column 2-4 mm long, white, papillate; perfect stamens 5, protruding from the flower, posterior one 7-9 mm long, lateral two 8-10 mm long, anterior two 8-10 mm long, 1-1.2 times the length of the sepals, white: staminodes 3-5 mm long; anthers dark red, ±2 mm long, pollen orange. Gynoecium: ovary 3.5-6 mm long; style 1.5-5 mm long, pale green; stigma branches 1-3 mm long, adaxially wine-red. Fruit: bases of mericarps ±5 mm long, with glandular hairs, tails 18-32 mm long. P. parvipetalum is one of the early-flowering species of section Hoarea and the peak of the flowering time is in September when leaves are still present.
