新发现的中国兰科一新记录种乳突金线兰

Anoectochilus papillosus—A New Record of Orchidaceae from China

报道在云南金线莲商品调查及产地跟踪调查过程中发现的一中国兰科金线兰属植物一新记录种--乳突金线兰(Anoectochilus papillosus Aver.),观察描述了形态特征及显微构造特征,重新编制了国产金线兰属分种检索表。该品种花瓣外侧中部具有一组由2~5个乳突状凸起组成的肉质附属物;唇瓣前部裂片近耳形;唇瓣中部褶片边缘波状或细齿状;距末端2深裂且近垂直于子房。该物种的发现表明金线莲的基原比预想的更加复杂,在开发利用这一民间名贵药材之前,应该重视并做好基原鉴定工作。
