摘要

描述了来自越南的 Yersinochloanianheana sp.它产于越南南部，海拔 1400-1500 米，位于林同省 Duc Trong 县 Voi 山。该新物种与同类物种 Yersinochloadalatensis 的区别在于：秆节有厚的膨胀髌骨，秆叶片直立，叶耳明显，边缘有长毛，内稃背视图显示小穗轴延伸，先端有不发育的小花，鳞片向顶端逐渐变紫。此外，本种与 Yersinochloanghiana 的区别还在于叶片基部不膨胀，先出芽 2 翻转，鳞被上半部紫色，基部不裂。

Yersinochloanianheana (Poaceae, Bambusoideae), a new species from southern Vietnam.

Yersinochloanianheana sp. nov. from Vietnam is described and illustrated. It is found in southern Vietnam, where it occurs at an elevation of 1400-1500 m in Voi Mountain, Duc Trong District, Lam Dong Province. This new species is distinguished from a similar species, Yersinochloadalatensis, by culm nodes with a thick swollen patella, culm leaf blades erect, auricles conspicuous, margins bearing long hairs, palea dorsal view showing rachilla extension and rudimentary floret at the apex and lodicules purple gradually towards the top. Besides that, the species is distinguished from Yersinochloanghiana by the leaf blades without being swollen at the base, the prophyllate bud 2-keeled, lodicules purple at ½ upper parts and unbifid at the base.
