Brachytheciaceae is one of the most diverse and problematic taxonomic families in pleurocarpous mosses. In this paper, the morphology of pseudoparaphyllia of 594 specimens in Brachytheciaceae, which belonged to 19 genera and 44 species, were studied. Results were as follows: ①In Brachytheciaceae, pseudoparaphyllia was triangular to semicircular foliose. According to its apical characteristics, pseudoparaphyllia could be divided into two types: truncate or obtuse, and acuminate. ②Except for the genus Brachythecium, morphology of pseudoparaphyllia among the different species in the other 18 genera was basically the same. ③Morphology of pseudoparaphyllia had taxonomic significance in the genus level.

Key words: pleurocarpous mosses, Brachytheciaceae, morphology, taxonomy
