本文报道了竹亚科镰序竹属一新种,即丰都镰序竹Drepanostachyum fengduensis Yi,它特产于重庆丰都县。它与坝竹（D.microphyllum（Hseuh et Yi）Keng f.ex Yi）的区别在于笋绿色,无紫斑,箨鞘无毛,箨片直立;叶鞘口两肩无繸毛;叶柄及叶片无毛,易于区别。将脱毛昆明实心竹Fargesia yunnanensis Hsueh et Yi f.detersa Yi et J.Y.Shi组合为脱毛实心竹Fargesia detersa（Yi et J.Y.Shi）Yi et J.Y.Shi,还将产于缅甸的Arundinaria elegans Kurz组合为雅致箭竹Fargesia elegans（Kurz）Yi。
