摘要:

大苞苣苔属(Anna Pellegr.)自1930年建立以来,学者对该属植物的分类修订甚少,早期的物种发表和修订都依据采集的标本完成,存在性状描述简略或不准确、物种界定模糊等问题。在对白花大苞苣苔 [Anna ophiorrhizoides(Hemsl.)B. L. Burtt & R. A. Davidson]和红花大苞苣苔(A. rubidiflora S. Z. He, F. Wen & Y. G. Wei)的历史考证、形态学对比和模式产地的调查考证中发现,1911年H. Léveillé发表的Didymocarpus cavaleriei H. Lév.与红花大苞苣苔实为同种,前者被处理为白花大苞苣苔的异名。在对白花大苞苣苔和红花大苞苣苔的多个居群形态特征对比和地理分布信息整理后发现,二者的形态特征有一定的差异,但仅依据花冠颜色作为种一级分类单位的界限并不恰当,综合考虑形态和地理分布特征,故提出将红花大苞苣苔处理为白花大苞苣苔的变种。依据2018年International Code of Nomenclature for Algae, Fungi, and Plants(Shenzhen Code)中的规定和建议,该文提出一个新组合兼新等级名称Anna ophiorrhizoides(Hemsl.)B. L. Burtt & R. A. Davidson var. cavaleriei(H. Lév.)X. X. Bai & F. Wen,并将红花大苞苣苔处理为新组合的异名。

Abstract:

Since the establishment of Anna Pellegr. in 1930, the taxonomic revisions of this genus have been infrequent. Early publications and revisions of Anna were based on specimens collected by foreign missionaries, which led to problems such as brief or inaccurate descriptions of traits and unclear species definition. When researching publication history, comparing morphology and investigating type locality of Anna ophiorrhizoides(Hemsl.)B. L. Burtt & R. A. Davidson and A. rubidiflora S. Z. He, F. Wen & Y. G. Wei, it was found that Didymocarpus cavaleriei H. Lév. published by H. Léveillé in 1911 and Anna rubidiflora was actually the same species, and Didymocarpus cavaleriei was treated as a synonym of Anna ophiorrhizoides. After comparing the morphological characteristics of multiple populations of A. ophiorrhizoides and A. rubidiflora, it was found that the difference in their morphological characteristics lay in the corolla. It was not appropriate to use differences in corolla color as boundaries for the classificatory units of species. Taking into account the morphological characteristics and geographical distribution characteristics, it was proposed to treat A. rubidiflora as a variety of A. ophiorrhizoides. According to the regulations and suggestions in the 2018 International Code of Nomenclature for Algae, Fungi, and Plants(Shenzhen Code), a new combination and a name at new rank —— A. ophiorrhizoides(Hemsl.)B. L. Burtt & R. A. Davidson var. cavaleriei(H. Lév.)X. X. Bai & F. Wen were proposed, and A. rubidiflora was treated as a synonym of the new combination.

Key words: Anna, Anna rubidiflora, Anna ophiorrhizoides, new combination, new synonym
