The genus T. H. Wen, endemic to southern China, is a small but taxonomically problematic genus of Arundinarieae (Poaceae, Bambusoideae). During field work, a population of from Zixing, Hunan, was discovered, appearing to be distinct from our previously identified collection. Comparisons of the population of Zixing were performed by using scanning electron microscopy (SEM) and a plastid genome-based phylogeny. Morphologically, it was mostly similar to , but differed by culm leaf erect with densely white pubescence, apical branch sheath much longer than the internodes and foliage leaf larger. Phylogenetically, the new species was well-supported as a sister to the clade of + , and the above three taxa were clustered in the clade (IV) of Arundinarieae. Thus, the new species, formally named as W.G.Zhang, G.Y.Yang & C.K.Wang, was described and illustrated herein.
温氏竹属特产于中国南方，是青篱竹族（禾本科，竹亚科）中一个较小但分类存在问题的属。在野外工作期间，发现了来自湖南资兴的一个种群，它似乎与我们之前鉴定的标本不同。通过扫描电子显微镜（SEM）和基于质体基因组的系统发育分析对资兴种群进行了比较。形态上，它与[某物种]大多相似，但不同之处在于竿箨直立且密被白色柔毛，顶端小枝的鞘远长于节间，且叶片较大。系统发育上，新物种被有力地支持为[某两个物种]分支的姐妹种，上述三个分类群聚集在青篱竹族的[某分类群]（IV）中。因此，在此描述并图示了这个正式命名为温氏[某竹种]（W.G.Zhang, G.Y.Yang & C.K.Wang）的新物种。
