慈竹一新变型和镰序竹属新异名

Neosinocalamus affinis (Rendle) Keng f. f,purpureo-striata Yi——a New Forma of Neosinocalamus affinis (Rendle) Keng f. from China (Babusoideae,Poaceae) and a New Synonym of Drepanostachyum Keng f.

  • 摘要: 本文报道了禾本科竹亚科慈竹属慈竹一新变型——紫条纹慈竹Neosinocalamus affinis (Rendle) Keng f.f.purpureo-striatus Yi。本变型幼秆下部节间绿色而间有宽窄不等的紫色纵条纹,与原变型有明显区别。花序小型、花序轴短等特征仅是量变,不足为属级划分标准。因此,岩竹属应是镰序竹属的一个新异名。

     

    Abstract: A new forma of the Neosinocalamus affinis (Rendle) Keng f. is reported in this paper. That is Neosinocalamus affinis (Rendle) Keng f. f. purpureo-striatus Yi. The lower internodes of its young culm are green with violet stripes. Its growing area is Dujiangyan City,Sichuan. Small lateral inflorescens and short rachires etc. are quantitative changes. It is not divisional standard of genus. Therefore Petrocalamus Z. P. Wang,N. X. Ma et W. Y. Zhang is a new synonym of Drepanostachyum Keng f.
