| 摘要: |
| 报道了广西兰科植物一新记录属:锚柱兰属(Didymoplexiella Garay)。该属植物为具肉质块茎的腐生草本,其体态近似于双唇兰属(Didymoplexis Griff.),但因前者的蕊柱上端扩大而具一对镰刀状的长翅,蕊柱足极不明显而相区别。该属植物在中国仅1种,即锚柱兰(Didymoplexiella siamensis),原记载分布仅台湾和海南,在广西十万大山的发现揭示了中国大陆与附近岛屿植物区系的紧密联系。文中还描述了锚柱兰的分类学特征,并提供彩色图版以资识别。 |

| Abstract: |
| Didymoplexiella Garay, a newly recorded genus of Orchidaceae from Guangxi, China is reported. This genus is closely related to Didymoplexis Griff., but is distinguished from it by the presence of elongate, filiform stelidia that extend from the column wings and by the absence of a column foot. Didymoplexiella siamensis only distributed in Taiwan and Hainan island, China, but now it is also discovered in Shiwandashan National Nature Reserve of Guangxi. Detailed morphological description and field photos were provided,and the biogeographic significance of the discovery was discussed. |
