Physospermopsis Wolff


Description from Flora of China

Haploseseli H. Wolff & Handel-Mazzetti.

Herbs perennial, glabrous. Taproot usually long, conic. Stem ribbed, base covered with fibrous sheath remnants. Leaf blade obovate-lanceolate, broadly triangular to oblong, 1–2-pinnate, rarely entire. Umbels terminal and lateral; bracts many, prominent, leaf-like, base entire, apex 3-lobed or pinnate; bracteoles present, entire or 3-lobed to pinnate. Calyx teeth minute or inconspicuous. Petals obovate, white, yellowish or dark purple, base shortly claw-like, apex obtuse-rounded or with shortly inflexed tips. Stylopodium flattened, margin sinuolate; styles about as long as stylopodium. Fruit ovoid to broadly ovoid, base slightly cordate, apex gradually narrowed, slightly flattened laterally, young fruits usually emerald green; ribs 5, filiform, prominent; vittae 2–3 in each furrow, 2–4 on commissure. Seed face plane to concave. Carpophore parted at apex.

This is a taxonomically complex genus in which species boundaries are not always clear, and generic limits (e.g., with Pleurospermum, Tongoloa, and Trachydium) are problematic. Physospermopsis is one of a group of high-altitude Sino-Himalayan genera in need of a revision treating all taxa across their whole geographic range.

About ten species: Sino-Himalayan region; eight species (four endemic) in China.
