A new species, Nothapodytes amamianus Nagam. & Mak. Kato, is described from Amami-oshima, the Ryukyu Isls., and information on its pollination biology is presented. Nothapodytes amamianus is closely related to N. nimmonianus (J. Graham) Mabb., which is widely distributed from S. India to the Ryukyus (Yaeyama group), but is distinguished from the latter by the base of the leaves truncate or shortly cordate, the larger flowers with petals 7-9mm long, and the short but prominent anther connective. This new species is restricted to a small area on Amami-oshima and should be categorized as critically endangered. A key to the Japanese species of Nothapodytes is provided.

Carex noguchii J. Oda & Nagam. is described as new to science. It is similar to C. biwensis Franch. in having irregularly trigonous to pentagonous culms, many-flowered (ca. 30) spikes, and short (1.8-2.0mm long) perigynia. Carex noguchii is distinguished from the latter, however, by the dark brown basal leaf sheaths, wider and longer leaves, orbicular-ovoid perigynia, and achenes loosely enclosed by the perigynia, and micromorphologically by the absence of satellite bodies.
