Synotis nyalamensis (Asteraceae, Senecioneae), a new species from southern Xizang (Tibet), China

Abstract

Synotis nyalamensis (Asteraceae, Senecioneae), a new species from Nyalam county in southern Xizang (Tibet), China, is described and illustrated. It is most closely similar to S. kunthiana, a species occurring in northwestern India, Nepal, and Pakistan, in having abaxially white-tomentose leaves and cylindric-campanulate capitula, but differs by having higher stature (45–60 vs. 20–40 cm), singular (vs. several) stems, caudate-acuminate (vs. acuminate) leaf tips, prominent (vs. obscure) nerves on abaxial side of leaves, and more disk florets (15–24 vs. 7–12).
