Abstract
Yushania tongpeii D.Z.Li, Y.X.Zhang & E.D.Liu, a new species of the temperate bamboo tribe Arundinarieae (Poaceae: Bambusoideae), is described and illustrated from north-eastern Yunnan, China. Yushania tongpeii is characterised by taller branching from nodes 1–2 m above the ground, usually three branches at the node, sparse purple spots and thin white powder on the internode, densely purple-spotted culm sheaths, glabrous margins of culm sheaths and tomentose leaf ligules. Based on the morphological features, this new species is assigned to section Yushania.

In order to know more about its habitat, distribution range and morphological features, we revisited Sanjiangkou, Wumengshan National Nature Reserve in September 2018 and more specimens were collected. We described it as a new species, i.e. Yushania tongpeii D.Z.Li,Y.X.Zhang & E.D.Liu
Summary
Yushania P.C.Keng, (1957) is one of the largest genera of the tribe Arundinarieae (i.e. the temperate woody bamboos) (Poaceae, Bambusoideae). Species of Yushania are characterised by the long-necked rhizomes, diffuse culms, one to many branches at the node, semelauctant and paniculate inflorescence and three stamens (Li et al 2006). Most taxa of this genus were described without reproductive features due to infrequent flowering. One of them has long-necked rhizomes, usually three branches at the node and occurs at elevations around 2300 m These characters are typical of the genus Yushania. We described it as a new species, i.e. Yushania tongpeii D.Z.Li,Y.X.Zhang & E.D.Liu
