| 摘要: |
| 枝毛野牡丹(Melastoma dendrisetosum)属于野牡丹科野牡丹属,首次发表于1983年,而Chen & Renner(2007)则将其归入了毛菍(M. sanguineum)。为弄清二者的区别及枝毛野牡丹的分类地位,该研究采用野生地实地考察、各大标本馆标本比较鉴定、引种地植株形态测定以及微形态扫描电镜观察,现已证实:枝毛野牡丹是明显区别于毛菍的一个独立的植物种,该种自然分布区极其狭窄,正处于极度濒危的生存状态。该文对枝毛野牡丹进行了最新的形态描述,为正确识别、积极保护该物种奠定了基础。 |

| Abstract: |
| Melastoma dendrisetosum(Melastomataceae)was first reported in 1983. Chen & Renner(2007)merged it within M. sanguineum. In order to clarify the difference between the two and the taxonomic status of M. dendrisetosum, a field investigation, herbarium survey, and an examination of morphological and micromorphological characteristics were performed. M. dendrisetosum was confirmed as a distinct species, obviously different from M. sanguineum. This species is narrowly endemic and extremely endangered. The study provides the latest morphological description of M. dendrisetosum, and lays a foundation for the precise identification and future conservation of this species. |
