The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large: botanists have described some 5,500 known species in about 90 genera, the largest being the "true sedges" with over 2,000 species.
Jisaburo Ohwi was Japanese botanist. He was a distinguished member of the Faculty of Science of Kyoto Imperial University. He is perhaps best known for his 1953 Flora of Japan.

Its chromosome number is 2n=52, with some variants reported, e.g. n2=54 for Greenland material.
Carex breviculmis, called the Asian shortstem sedge, is a species of flowering plant in the genus Carex, native to Asia from the Indian subcontinent to Southeast Asia, China, Taiwan, Korea, Japan, north as far as Khabarovsk Krai, and Malesia, New Guinea, Australia, Norfolk Island and New Zealand. It has been introduced to the US state of Mississippi. Typically found in forests, it is quite shade tolerant.
