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.)

摘要： 观察了我国节柱竹族(广义的)5属27种的地下茎解剖特徽，发现地下茎，尤其是竿柄，在本族的分属中有相当重要的意义。作者根据地下茎以及其它器官的特徽，对国产节柱竹族5个属之间的关系作了探讨，认为这5个属以各自独立为宜。
