蜡梅科9种叶的比较解剖*

对蜡梅科9种植物的叶片、叶柄及节部进行了比较解剖研究，结果表明蜡梅科叶片结构各种之间差别小，节部为具2侧迹的单隙类型；从叶柄侧迹数量看，支持蜡梅科原分为夏蜡梅属(Calycanthus Linn.) 和蜡梅属(Chimonanthus Lindl.) 两个属；而油细胞的分布与密度可以将蜡梅属分为无油细胞的蜡梅和西南蜡梅，及含有油细胞的柳叶蜡梅、山蜡梅、浙江蜡梅和突托蜡梅两类群。对浙江蜡梅、突梅蜡梅、柳叶蜡梅和山蜡梅之间从叶的解剖构造提不出质的差别。

Comparative Atanomy of Leaf from 9 species of Calyeanthaceae.

The leaves, petioles and nodes of 9 species of Calyeanthaceae were dissected. The 9 species all have two lateraltraces and one gape. The leaf structure shows slightly different. The lateral bundles in petiole show that the family can be devided into two genus: Calycanthus which has 3~6 lateral bundles; and Chimonanthus which has 2 lateral bundles. Based on the oil cell in leaf the Chimonanthus can be separated naturally into two groups: one has non-oil cell, such as Ch. praecox and Ch. campanulatus, the other has oil cells, such asCh. salicilolius, Ch. zheiiangensis, Ch. nitens and Ch. grammatus. It can not give qaulitative inforamtion to differ aomng the four species.
