浙江榧属植物叶片变异及其分类学意义
Leaf Variation of Torreya Plants in Zhejiang and its Taxonomic Implications
摘要
Abstract
The species of the genus Torreya are endangered and protective plants in China, and three species with one variety are recorded in Zhejiang.Based on the observation of leaf apex and base, together with the measure of leaf length, the variation patterns of these characters are analyzed, and the taxonomic significances are discussed in the present paper.The results are mainly as following: Leaf length shows all significant differences among the four taxa, while T.fargesii and T.grandis, T.grandis var.jiulongshanensis and T.jackii are both more or less overlapped in the pictorialized column diagram.The shapes of leaf apex in T.fargesii, T.grandis and T.jackii are all stable, while those of T.grandis var.jiulongshanensis are acuminate or acute.The shapes of leaf base in the four taxa are all stable.Leaf length of T.grandis var.jiulongshanensis shows considerably variable both in populations and among populations.A new combination, Torreya jiulongshanensis, is proposed here.关键词
