中国鱼腥藻属的两个新记录种

Two newly recorded species of Anabaena(Nostocales,Cyanobacteria) in China

迄今为止,全球范围共报道出100多种鱼腥藻,中国记录报道的仅有50余种,但有些种类的描述仍较模糊.最近在福建、浙江等地进行野外调查时,发现了多种丝状蓝藻.其中就有2种鱼腥藻在中国尚未报道:威格鱼腥藻(Anabaenaviguieri Denis et Frémy 1923)和史密斯鱼腥藻(Anabaena smithii(Komárek)Watanabe 1992).

So far, more than 100 species of genus Anabaena have been recorded in the world, and about 50 taxa were described in China. During our recent field investigations for water-bloom forming cyanobacteria in China, several filamentous cyanobacterial species were examined in the samples. In this study, we demonstrated that two Anabaena species as Anabaena viguieri Denis et Fremy 1923 and Anabaena smithii （Komarek） Watanabe 1992, had never been reported in China, and they are newly described and discussed in the present study.
