摘　要:在扫描电镜和解剖镜下研究鼠李科(Rhamnaceae)勾儿茶属(Berchemia)和小勾儿茶属(Berchemiella)共
１７种植物的果实和种子形态.结果表明:小勾儿茶属的核果１室,具１枚种子,勾儿茶属大多数种的核果２室,
每室具１枚种子,但多叶勾儿茶(B．polyphylla)的核果１室较大,具１枚种子,另一室较小而没有种子,该种可
能是连接勾儿茶属和小勾儿茶属的中间类群.这两个属的种子形状通常为不规则长椭圆形,种皮纹饰可划分为
光滑或几乎光滑、具不明显或稀疏的条纹以及具明显的条纹或沟这三种类型.种皮纹饰的差异对这两个属属下
种类的划分具有一定的意义.讨论了与前人研究结果不同之处和可能的原因.
