广东两种兰科植物新记录

    Two New Records of Orchids Plants in Guangdong Province

    • 摘要: 基于野外观察、文献查阅及标本比对,该文报道广东省两个野生兰科植物新记录种——云霄卷瓣兰(Bulbophyllum yunxiaoense M.H.Li, J.F.Liu & S.P.Chen)和血红肉果兰〔Cyrtosia septentrionalis(Rchb.f.)Garay〕,前者发现于广州市从化区,附生于大树树干上,后者发现于韶关市始兴县车八岭国家级自然保护区,生于近山顶的阴坡竹林下。该文还提供两种植物的形态描述和彩色图版,凭证标本保存于中国科学院华南植物园标本馆(IBSC)及车八岭国家级自然保护区标本馆。这些新记录进一步丰富广东省兰科植物的多样性,对今后开展兰科植物的地理分布和种群起源与扩散研究有一定意义。

       

      Abstract: Based on field observation, literature review and specimen comparison, this paper reports two new records of wild orchids in Guangdong Province, namely Bulbophyllum yunxiaoense M.H.Li, J.F.Liu & S.P.Chen and Cyrtosia septentrionalis (Rchb.f.) Garay, with the former discovered in Conghua District, Guangzhou City, epiphytic on the trunks of large trees, and the latter in Chebaling National Nature Reserve, Shixing County, Shaoguan City, growing under the shady-slope bamboo forest near the mountain top. Detailed morphological descriptions and color plates for the two species were also provided. The voucher specimens are deposited in the herbaria of South China Botanical Garden, Chinese Academy of Sciences and Chebaling National Nature Reserve. These new records further enrich the diversity of Orchidaceae in Guangdong Province, and are of certain significance for future studies on the geographical distribution, population origin and dispersion of Orchids.
