Shibataea Makino is a genus of Subfam. Bambusoideae, with 8 species, distributed
in Southeast China and Southwest Japan. In China wild plants of the genus are found in
Fujian, Jiangxi, Zhejiang, Jiangsu and Anhui provinces, especially in Fujian and Zhejiang.
The genus is also cultivated in parks of Guangzhou, Teibei and some other gardens.
Raches of inflorescences in genera Semiarundinaria, Brachystachyum, Phyllostachys and
Shibataea have many branches, even secondary branches. A large bract is often present at the
base of each branch, and a prophyll in the axil of the bract in Tribe Shibataeeae Nakai. Mo-
reover, an inflorescence is composed of numerous dense spikelets. This type of inflorescence
may be considered primitive. The genera Indosasa and Sinobambusa are of more stamens (6
in the former and 3 or 4, 5 in the latter) than in the genera Semiarundinaria and Brachysta-
chyum (only 3), and their inflorescences are very simple with fewer spikelets and raches,without the large bract. This type of inflorescence may be considered more advanced. 相似文献

描述了旌节花属（旌节花科）西域旌节花Stachyurus himalaicus Hook.f.&Thom
s.ex Benth.一新亚种:紫红旌节花S.himalaicus ssp.purpureus Y.P.Zhu&Z.Y.Zhang。该新
亚种与原亚种S.himalaicus subsp.himalaicus的区别在于原亚种的花为黄色或黄绿色，而新
亚种的花为粉紫色至深紫色。此外，原亚种多生长于1300-3000m的落叶或常绿阔叶林中或林
缘，分布区由东喜马拉雅至我国西南广大地区，而新亚种仅见于东喜马拉雅地区2200-3300m
的密林中。 相似文献
