Comparative Observation on Venation of Calycanthaceae

摘要: 对蜡梅科３属５种进行叶片脉序的比较观察，结果表明，它们的一级级中等车，二级侧脉较多，与一级脉连接形成环节曲行羽状或网节曲行羽状脉，二级脉弧曲上升，三级脉贯穿型或结网型，叶缘末端为不完全型；网眼大小、形状不规则、发育均为不完善型。

Abstract: The present paper conducts the comparative observation on leaf venational morphology of 3genus and 5 species in Calycanthaceae. The result shows that 1st veins are moderately stout,2nd veins are much more, 1st veins conshtute brochido-camptodromous or reticulo-camptodromous pinnatoides with 2nd veins; 3rd veins are percurrent or reticulate, at the margin; veinlets are incomplete, areole has not a norm in shape and area, it is imperfect in system development.
