Pertya huangii (Asteraceae), a New Species from Yunnan, Southwest China

Pertya huangii Huan C. Wang & Q.P. Wang (Asteraceae) is described and illustrated as a new species endemic to Yunnan, southwest China. It belongs in Pertya sect. Pertya and is the westernmost species hitherto known for this section in China. Pertya huangii is most similar to P. hossei, but clearly differs from the latter by its terete, densely villous or sometimes glabrescent branchlets, abaxially villous leaves with a mucronate to acute apex and slightly dentate margin, leaf blades of long shoots being rounded at the base, and villose phyllaries.
