中国卷柏科植物的研究(Ⅰ):卷柏属同形叶亚属(英文)

Studies on the Chinese species of Selaginellaceae (Ⅰ):Selaginella subgenus Tetragonostachys Jermy

对中国卷柏科卷柏属同形叶亚属进行了分类学修订 ,首次承认中国分布有 3种 ,即西伯利亚卷柏S .sibirica ,印度卷柏S .indica和细瘦卷柏S .vardei。绘制了每种的叶形 ,孢子叶穗线条图 ;并绘有同形叶亚属植物的地理分布图。该亚属在中国的分布呈西南和东北分布格局。

The Chinese species of Selaginella subgenus Tetragonostachys are revised. Three species are distinguished in the present study, i.e. S. sibirica, S. indica and S. vardei . Illustrations of the leaves and strobili, distribution maps of the subgenus and the species occurring in China are made to facilitate easy identification of the species. The distribution of the species in China shows an interesting southwestern China and northeastern China distribution pattern.
