摘要:

海南是我国的热带岛屿,植物资源丰富。近年来,在海南省霸王岭国家级自然保护区的野外考察中,发现天麻属(Gastrodia)一新记录种Gastrodia punctata Aver.。该种原为越南特有种,根据拉丁名种加词之意及形态特征将其定名为“白点天麻”。白点天麻具有以下特征:花被筒褐色,被白点,唇瓣具4条肉质脊突,蕊柱基部具明显的镰刀状柱头,易与该属的其它种类相区别。该文中还提供了该种的中文形态描述及彩色图片,并对其分布和保护状况进行了报道。

Abstract:

Hainan is the tropical island of China which is remarkable for its rich plant resources. During our field trips to Hainan Bawangling National Natura Reserve, Gastrodia punctata Aver., a newly recorded species of Gastrodia from China, was discovered and here reported. This species was previously considered as endemic to Vietnam. Its Chinese epithet was entitled by the meaning of specific epithet and morphological characters. It could be identified from other species of this genus by the brown sepals with numerous lager white spots, four keels on the lip and the falcate stigma located at the base of column. In this paper, its Chinese description, color illustrations, distribution and conservation status were provided as well.

Key words: China, Gastrodia punctata Aver., Hainan, new record, Orchidaceae
