| 摘要: |
| 应用光学显微镜观察了镰序竹属与悬竹属共10个种叶的横切面和表皮结构,对分类学上有争议的种的分类地位进行探讨。结果表明:(1)镰序竹属与悬竹属叶的结构差异较大,应单独立属;(2)羊竹子、巴竹、冕宁镰序竹及碟环竹叶的结构与镰序竹属各种相近,它们应归于镰序竹属;(3)扫把竹的形态和解剖特征与镰序竹属各种差异显著,不宜放入镰序竹属,而应恢复到箭竹属中。 |

| Abstract: |
| After examining the cross section of leaf and leaf epidermis of 10 species of genus Drepanostachyum and Ampelocalamus applying optical microscope,and probed the position of disputed species and concluded:(1)the anatomical structures of Drepanostachyum and Ampelocalamus are different obviously,so they should be separated to be 2 genara;(2)the anatomical characters of D.saxatile,D.yongshanensis,D.mianningensis and A.patellaris are more close to that of Drepanostachyum and they should belong to Drepanostachyum;(3)the morphologic and anatomical characters of D.fractiflexum are different dramatically from that of Drepanostachyum and it should belong to Fargesia. |
