Abstract: After examining the anatomical characters of the rhizomes of 27 species belonging to 5 genera of Chinese Arthrostylidiae, the authors discorved that the rhizomes, especialy the culm necks, have some taxonomic importance in the tribe. According to the characters of rhizomes to-gether with those of the other organs, the authors descussed the interrelation among the 5 genera and supported to keep these genera separate.

Key words: Arthrostylidiae (s. 1.)
