中国算盘子属(叶下珠科)果实形态特征及其分类学意义

Fruit morphology of Chinese Glochidion (Phyllanthaceae) and its taxonomic implications

  • 摘要: 算盘子属是一个分类较为困难的大类群,全世界超过300种,其中众多物种间的界定至今颇存争议。本研究在野外考察及对馆藏标本查阅的基础上,对中国算盘子属21种1变种的果实形态进行了仔细观察和研究。结果显示,该属物种果实被毛情况、果实大小、宿存花柱、纵沟深浅和数目等形态特征在种间具有很高的多样性,可用于对不同物种的鉴别,具有一定的分类学价值。基于果实形态特征提供了这21种1变种的分类检索表。

     

    Abstract: Glochidion is a taxonomically difficult genus with more than 300 species, among which the circumscriptions are disputable. Based on extensive field investigation and detailed study of herbarium specimens, the fruit morphological characteristics of 21 Chinese Glochidion species were recorded and analyzed. Results indicated that most morphological characteristics of the fruits, such as fruit trichome, size and persistent styles, as well as the morphology and number of fruit grooves, exhibited high diversity and could be used in distinguishing the different species studied. In addition, a key to the Glochidion species studied is provided.
