报道了中国大陆兰科(Orchidaceae)一新记录种:闭花天麻(Gastrodia clausa T. C. Hsu, S. W. Chung&C. M. Kuo),凭证标本馆藏于中国科学院华南植物园标本馆(IBSC)。闭花天麻以联合花被管短且闭合,花辐射对称,唇瓣花瓣状,合蕊柱腹部具显著附属物而易与该属其他种类区别。提供了该种的描述、解剖照片及分类学信息。
A newly recorded myco-heterotrophic orchid, Gastrodia clausa T. C. Hsu, S. W. Chung & C. M. Kuo, is reported from Dinghushan National Nature Reserve in Guangdong, China and the vouchers are kept in the herbaria of South China Botanical Garden, Chinese Academy of Sciences(IBSC). It is distinguished by the short enclosed or hardly opening perianth tube and peloric flower with a small, petaloid lip conjoint with the perianth tube and a prominent ventral appendage of column. Detail morphological descriptions, colour plate and taxonomic notes on the species are provided.
