Abstract

Physospermopsis siamensis Esser & M.F.Watson is described as a new species from material collected in northern Thailand. This is the first record of Physospermopsis (Umbelliferae, Apiaceae) from Thailand, and represents a significant southern extension of the geographic range of this largely Sino-Himalayan genus. Comparison is provided with P. shaniana, its closest morphological ally, and the key to genera given in the Flora of Thailand account for Umbelliferae is revised.
