摘要
柔毛筇竹(Chimonobambusa puberula)和光竹(Chimonobambusa luzhiensis)最初均基于中国贵州西部六盘水市六枝特区标本描述。原始文献认为二者在节间和节下被毛、枝条形态、秆箨宿存与否及背面刺毛、叶片大小等方面存在差异。在比较研究馆藏标本、原始文献和模式产地野外居群考察的基础上,确认二者在节间和节下被毛性状不稳定,叶片大小等性状上差异并不间断,其他特征也一致,二者为同种植物,加之分布区重叠,生长环境类似,物候期一致,因此将Ch.luzhiensis处理为Ch.puberula的异名。
Chimonobambusa puberula and Ch.luzhiensis are both originally described based on the materials from Liuzhi Special District of Liupanshui city in western Guizhou,China.The original literature holds that the two species differ in the indumentum type on internodes and below nodes,branch shape,culm sheaths,the bristles on sheath back,and leaf size.Based on comparative study of the herbarium specimens,the protologues and field investigation,it is confirmed that Ch.puberula and Ch.luzhiensis are unstable in terms of the indumentum type on internodes and below nodes,persistently different in the leaf size and other traits,and the same in other characteristics.The two species are conspecific,with sympatric distributions and the same habitat and phenology.It is therefore necessary to treat Ch.luzhiensis as a synonym of Ch.puberula.
