竹亚科单枝竹属芸香竹花枝和花特征补充描述.

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.
