摘要：
Isoetes orientalis is a previously undescribed, rare, and endangered quillwort of southeast China with a hexaploid chromosome count of 2n = 66. Megaspores of I. orientalis have a reticulate ornamentation consisting of irregularly anastomosing muri with ragged crests. Microspores have an echinate-tuberculate ornamentation. Herbarium specimens of L orientalis previously have been misidentified as I. sinensis. Isoetes orientalis differs from I. sinensis in spore morphology and chromosome number.
