摘要

摘要: 花序是生花的分枝结构或系统, 通常是被子植物科的重要特征, 与传粉密切相关。花序教学的困难可能来自各教材在花序定义和分类上存在的问题。本文重新定义了一些花序类型, 如有限和无限花序、伞房花序、轮伞花序, 也澄清了伞形花序、柔荑花序、头状花序和隐头花序等花序分类上的一些混乱。笔者提议将花簇生和因花序退化而形成的单花列为花序类型。最后, 本文提出了一个新的花序分类系统, 增加了一些分类单元。

Abstract

Abstract: Inflorescences, the branching structures or systems that bear flowers, are usually important fea-tures of angiosperm families and closely related with pollination. Troubles in the process of inflorescence teaching may partially come from the inflorescence definitions and classification in various botany textbooks. This paper redefined some inflorescences, such as determined and indetermined inflorescences, corymb and verticillaster, and cleared up some confusion in classification of umbel, catkin, capitulum and hypanthodium. Secondly, the paper suggests that both a cluster of flowers and a single flower degenerated from an inflores-cence should be regarded as types of inflorescence. Finally, a new classification of inflorescence is proposed, in which some new groups are added.
