摘要
A new moss species, Homaliodendron pulchrum, from China, is delimited by its distinct morphology and biogeography. The new species has oblong-spathulate to obovate leaves and an indistinct double costa, which is unique within the genus. Distribution of this new species is restricted to three localities in southwestern and southern China. The new species is described and illustrated and a key to the species of Homaliodendron in Eastern Asia is provided. The systematic position of H. pulchrum is revealed to be sister to H. montagneanum by molecular evidence based on the parsimony and maximum likelihood analyses of nad5 and rps4 sequences.
