Some New Taxa of Nitella from Guangdong, China
广东丽藻属新植物

Guangdong Province extends across the subtropical and tropical zones. With favorable climate and plentiful rainfall, this district is extremely rich in plants. However, the study on the Charophyta in this province is scanty. The specimens we identified were collected from 4 cities and 10 counties of the province. The result shows that there are abundant representatives of Chrophyta, espe- cially in Nitella, in the province. In this paper, however, only reported are some new taxa of Nitella. The 2 new spe- cies are Nitella sessilis and N. guangdongensis; the 3 new varieties are Nitella flagellifor- mis var. conglomerata, N. brevidactyla var. hainanensis and N. pakistanica var. magni- antheridii; and the 3 new records of distribution in China are Nitella bengalensis Kundu, N. madagascariensis Zanev. and N. tenuissima var. sanukensis Imah.
