| 摘 要： | 对中国云实属植物小叶叶片脉序的观察表明,该属植物小叶叶片脉序类型非常一致,均为环结曲行羽状脉,二级脉急转曲行.叶脉分支一般为四级,少数达五级.盲脉不分支或分支较少,最多两次分支.见血飞亚属与云实亚属叶片脉序特征相似,属于同一自然类群.编写了中国云实属植物叶片脉序特征分种检索表.

| Abstract: | Leaf venation of all the 20 species of Caesalpinia occurring in China were studied. Venation patterns of the leaflets in the genus studied are all brochidodromous. The secondary veins are abruptly curved. The highest vein order is quaternary or quinternary. Veinlets are simple, or once or twice branched. Leaf venation characters show that both Caesalpinia s.s. and Mezoneurum are in a natural group. A key to the species of Caesalpinia based on leaf venation characters is presented. |
