The distribution and ecology of Carex matsumurae Franch. (Cyperaceae) were studied in Japan. The distribution area of this species was from the northern Ryukyu Islands through Kyushu and Shikoku to the Hokuriku district on the Sea of Japan side and to the Izu Islands on the Pacific side. More than 50% of the localities were on islets with areas of less than 1km^2 and the species can be considered to be an islet-biased plant. This species grew on the forest floor in the Persea thunbergii type of lucidophyllous forest, which is distributed in the coastal areas of warm-temperate zones. The young plants and the seedlings of this species were mostly found at bare micro-site in the forest developed on a slope, but not at litter-deposited site in the forest developed on a flat plane. The current distribution can be explained by the fact that most of the natural forests in the coastal area of warm-temperate zones were destroyed and C. matsumurae was extinct in many places on large islands and mainland.
