摘 要: 对已有的标本信息进行研究,并对野外做进一步的补充调查,结果表明,金钟藤虽然主要分布于热带,但亚热带也有分布;以往认为该种是热带植物的观点是不确切的。金钟藤的地理分布原有三个中心,第一个是中国的海南岛;第二个是加里曼丹岛(现在的马来西亚的沙劳越和印尼的东加里曼丹岛);第三个在中越边界的是越南北部的沙巴、先安等,老挝的湄公河流域,以及中国广西、云南靠近越老边界的地区。而广州及其附近地区正逐渐成为金钟藤新崛起的一个分布中心。 The distribuion of Merremia boisiana was discussed based on field investigations and existing specimen information.Results indicated that Merremia boisiana mainly distributed in tropic, but it also distributed in subtropic. Therefore, it was not correct that the species was a tropical one. The species had three distribution centers: the first one was in Hainan Island, China, the second one was Kalimantan Island (Sarawak of Malaysia and East Kalimantan of Indonesia) and the other one was in Cha-Pa, Tien-Yen of Vietnam, in Megong area of Laos, and the region in Guangxi bordering Vietnam and Laos. Guangzhou and its vicinity was gradually becoming a new distribution center.
