Todashiba - Todashiba

Japanese: トダシバ - とだしば

A perennial grass of the grass family (APG classification: Poaceae). The rhizome is developed and creeps underground. The culms are clumpy and the leaves are somewhat hairy. From August to October, a panicle blooms at the top of the culm. The spikelet is 3.5 to 4.5 mm long and has two florets. If there are any awns, they are very short. The fourth glume is small and has a short tuft of hairs at the base. It commonly grows on sunny hills, and is distributed from Hokkaido to Kyushu, as well as the Korean Peninsula, China, and Ussuri. The name comes from the fact that it was often found in Toda-ga-hara near Tokyo (now the Arakawa River basin in Toda City, Saitama Prefecture).
