摘要:

本文报道了广西的轮藻新植物。在这些新分类群中,单顶丽藻(Nitella haplodactyla)为雌雄异
株,能育小枝仅具1枚末射枝;短枝丽藻(N.brachyclema)和稀见丽藻(N.rarissima)的末射枝都
是多细胞;拟扇形丽藻四强变种(N. pseudoflabellata var.tetradynana)的能育小枝为四强式的射
枝;松状轮藻(Chara piniformis)的主要特征是具有单列式皮层、长的刺细胞和退化叶托的。

Abstract:

 Guangxi, Situated in the southern border area of China, is extremely rich in Ch-
arophytes. In this paper, however, reported are only new species and new varieties. Among the
new taxa, Nitella haplodactyla has only one dactyl on the fertile branchlet, N. brachyclema and
N. rarissima are provided with more than 4-celled dactyls, the fertile branchlet of N. pseudofl-
abellata var. tetradynana has tetradynamous rays, and Chara piniformis is characterized by the
haplostichous cortex, long spinecells, and rudimentary stipulodes.
