最近,在鉴定我国西沙群岛海产蓝藻标本时,发现采自东岛的一号标本为博氏藻属Borzia Cohn的一个新种——西沙博氏藻Borzia xishaensis sp.nov.。同时,在镜检大量标本的基础上,发现该新种的繁殖方式较特殊,迄今在颤藻科Oscillatoriaceae中是罕见的。现将其形态特征及繁殖方式报道如下。 Recently, during the identification of marine blue-green algae specimens from the Xisha Islands in China, it was found that the No.1 specimen collected from the Dong Island was Borzia xishaensis sp. Nov., A new species of Borzia Cohn from Bordeaux. At the same time, based on the microscopic examination of a large number of specimens, the new species was found to reproduce in a rather special way and so far it is rare in Oscillatoriaceae. Now its morphological characteristics and propagation methods are reported as follows.
