Abstract:
Fissidens macaoensis L. Zhang is described as a new species from Macao, South China. The species can be separated from its congeners by a suite of characters, including (1) minute size; (2) subterraneous tubers, composed of one to several cells, growing laterally from mature rhizoids; (3) abundant rhizoidal gemmae found on the surface of the soil and which are developed from subterraneous rhizoids; and (4) relatively large cells of the leaf lamina. This is the first report of a moss where two types of vegetative diaspores occur simultaneously in a single individual. Their adaptation strategy is briefly addressed.
