摘要： 通过对本属48 个分类群的检查, 发现女贞属的种子有4 种类型: 1 ) 小球形, 2) 卵形, 3 ) 椭圆形,4) 具沟形, 并且它们与果实的类型有密切的相关性。因此, 以种子的形态以及内果皮的类型为主要分组依据, 提出了一个新的分类系统。此外, 本文将L. xingrenense 作为L. nepalense 的地理亚种处理; 将L. longipedicellatum和L. yunguiense 归并到L. lianum; 将L. longitubum 及L. robustum subsp. chinense 分别归并到L. leucanthum
及L. expensum。真正的粗壮女贞L. robustum 分布于斯里兰卡、印度及缅甸等地, 未见于我国, 文献上所载产于我国的粗壮女贞均为L. expansum 的错误鉴定。

Abstract:

Based on an extensive examination of specimens of 48 taxa in the genus Ligustrum, it was found that four types of seeds could be divided: 1) sphaercular, 2) compressed ellipsoidal, 3) compressed ovoid , and 4) crescent-shape with two channels on the back . There is a close relationship between the form of seeds and the type of fruit . Thus, a new infrageneric
system of Ligustrum is proposed based on the morphology of seeds and endocarps . In addition , L. xingrenense is regarded as a subspecies of L. nepalense; L. longipedicellatum and L. yunguiense are treated as synonyms of L. lianum; L. longitubum and L. robustum subsp . chinense are synonyms of L. leucanthum and L. expansum respectively . L. robustum only occured in India , Burma and Sri Lanka but not in China . The records of L. robustum in China are based on misidetifications of L. expansum .
