国家Ⅱ级重点保护野生植物四药门花研究进展

通过对文献和多个网络资源数据库(植物志、标本、图像库等)分析考证,及赴部分产地野外实地考察,对国家II级重点保护野生植物四药门花Loropetalum subcordatum的分类学地位、研究进展、标本记录、产地与生境、濒危因素及保护建议等进行综述,以期为该保护物种的生存、发展和保护提供参考。四药门花自1857年在香港采到标本和1861年被命名以来,其研究已有160多年的历史,分布区范围从最初的香港,扩展至广西、贵州和广东。2019年1月作者等在广东台山上川岛发现的四药门花种群,是迄今发现的分布最南、海拔相对较低的野生种群。四药门花濒危的主要原因是间断分布、自身繁殖力低、生境的人为干扰等,文中就其保护措施提出了建议。

Research Progress on Loropetalum subcordatum Listed in Class II of State Key Protected Wild Plants

Based on the analysis of references and internet resource databases, including flora, specimens, and pictures, and also the field survey on some of the wild survive sites, the taxonomic status, research advance es, specimen records, places of origin and habitats, and the present endangered situation of the key national protected grade II plant Loropetalum subcordatum, were summarized in this paper, so as to providing some information for its survivals and development. There had been more than 160 years since the specimen was collected in 1857 and named in 1861 first found in Hong Kong. According the research, its areal range was enlarged from endemic to Hong Kong, to Guangxi, Guizhou and Guangdong. The population found by authors in Shangchuan Island Macaque Provincial Nature Reserve of Taishan, Guangdong in January, 2019, was the most southern and relative low altitude population found at present. The main cause of its endangerment was its disjunctive distribution, low fecundity, disturbance of the habitat. Some suggestions on the protection measures were put forward in this paper.
