Abstract: Based on field survey, inspection of herbarium specimens and literature review, the floristic characteristics and natural population structures of orchids in Huidong Lianhuashan Baipenzhu Provincial Nature Reserve were studied. The results showed that there were 40 species from 27 genera of Orchidaceae in Lianhuashan Baipenzhu Nature Reserve, including 26 terrestrial species, 13 epiphytic species and 1 saprophytic species. They mainly grew in the less-disturbed secondary forest or near streams. The genera have 8 geographic elements and the species have 6 geographic elements, both of which were dominated by Tropical Asia element. Comparing with neighboring nature reserves, orchid composition of Baipenzhu was most similar to Qimuzhang with 71.11% and 61.11% of generic and species similarity, respectively. In addition, one new record species to Guangdong province (Lecanorchis nigricans) and one new population of Apostasia shenzhenica were reported.

摘要: 基于野外实地调查和文献记录,分析广东惠东莲花山白盆珠自然保护区的野生兰科植物物种多样性、属种地理分布特点及其种群结构。结果表明,白盆珠保护区野生兰科植物有40种,隶属于27属,包括地生兰26种、附生兰13种和腐生兰1种;以人为干扰较少的山林和溪谷沟边较为丰富。白盆珠保护区兰科植物属和种的地理成分均以热带亚洲分布成分为主,与邻近地区七目嶂保护区最为相似,两地的属种相似性系数分别达71.11%和61.11%。此外,调查中发现1个广东省兰科植物新记录种全唇盂兰Lecanorchis nigricans,及深圳拟兰Apostasia shenzhenica 1个新分布点。
