海南岛的粉枝藻属 Liagora 种类是热带性藻类,资源很丰富。1941年曾呈奎报导过6种,内有两新种。作者自1974年以来,在海南岛东岸沿海先后采到本届藻类共280编号标本,其中有很多是生长在低潮带下的深水种类。经过几年来用胚胎分类方法的研究,发现除了我国未报导过的新纪录外,还有新种和新属。本文首先报导两种新纪录。 Hainan Island pink algae Liagora species are tropical algae, is very rich in resources. In 1941, Tseng Kweikui reported 6 species, including two new species. Since 1974, a total of 280 algae samples have been collected along the east coast of Hainan Island. Many of them are deep-water species that grow under low tidal range. After several years of research using the embryo classification method, it has been found that in addition to the new records not reported by our country, there are also new species and new genera. This article first reports two new records.
