台湾竹种的花。本文以日本伊豆群岛的三仓岛为研究对象，根据花的新特征，提出了三仓岛的新种属地位。将该种与近缘种S.kurilensis和S.长25-36（-40）mm，宽7-12 mm;生殖器官椭圆形，长17-21.5 mm，椭圆形，不休眠; Sasa jotanii可能与S. kurilensis属于Mαcrochlamys组。
Flowers of Sasa jotanii (Poaceae: Bambusoideae) from Isl. Mikurajima, Izu Islands, Japan, are observed on the basis of new flower characteristics and a new specific status of it is proposed here. Comparing the species with the most related alies, S.kurilensis and S. tsuboiana, S.jotanii is characterized by a large fusiform, incanus reddish-purple spikelet 25-36 (-40) mm long, 7-12 mm wide, extremely large eliptic non-dormant caηopsis (14.5-) 17-21.5 mm long in reproductive organs~ its les decumbent culms, coriaceous and waxy foliage leaves, and lanceolate leaf blade without oral setae and sheath-margin fimbriae in sterile organs. Sasa jotanii is probably most closely related to S. kurilensis belonging to the section Mαcrochlamys.
