| 繁殖器官在竹类植物的分类学研究中具有重要意义,研究组在广西马山县观察到竹亚科单枝竹属芸香竹正在开花,该文根据观察到的开花状况和采集到的标本解剖观察结果,对其花枝和繁殖器官特征做了详细的中文及拉丁文补充描述。经对比芸香竹与属内已知繁殖器官结构的单枝竹和小花单枝竹的繁殖器官,3个竹种有相同的繁殖器官结构特征,但在小花数目和大小等方面具有差异。繁殖器官比较表明该属竹种的繁殖器官对喀斯特地貌环境有特殊的适应性,也支持依据营养器官差异划分为3个独立竹种。 |

| Abstract: |
| Reproductive organs are of great significance in taxonomic studies of bamboo plants. In this paper, Latin and Chinese supplementary descriptions are provided for flowering branches and reproductive organs characteristics of bamboo species Bonia amplexicaulis distributed according to observed flowering condition and anatomical observation results of the collected specimens in Mashan County, Guangxi. By comparing the floral characteristics of the reproductive organ structures of Bonia species B. saxatilis, B. parvifloscula and B. amplexicaulis, the three species have the same reproductive organ structure characteristics, but there are differences in the number and size of florets. The comparison of reproductive organs shows that the reproductive organs of Bonia species have special adaptability to karst geomorphic environment, supports that they are independent species according to the differences of nutritive organs. |
