摘　　要：本文观察和描述了单种属长果安息香属和秤锤树属５种植物的叶脉特征。结果表明，两属植物的脉序特征比较一致；但各种之间也存在一些差别，根据这些差别可编出分种检索表；长果安息香与秤锤树属各种的三级脉特征明显不同。In this paper, the leaf venation patterns of the monotypic genus Changiostyrax C.T.Chen and 5 species from Sinojackia Hu have been observed and described. The results indicate that venation patterns of these species are similar in general but distinct from each other in a number of characteristics. Based on the different characteristics, a key to species is provided. The results also show that the character of the tertiary veins in Changiostyrax dolichocarpa(C. J. Qi)C. T. Chen is obviously different from that of those in the species of Sinojackia Hu,This difference supports the separation of Changiostyrax from Sinojackia by one of the authors.
