摘要: |
大苞苣苔属自1930年建立以来,对该属植物的分类修订虽并不频繁,但早期的发表和修订都依据国外传教士采集的标本完成,存在性状描述简略或不准确,物种鉴定模糊等问题。通过对白花大苞苣苔[Anna ophiorrhizoides (Hemsl.) Burtt & Davidson]和红花大苞苣苔(Anna rubidiflora S.Z.He, F.Wen & Y.G.Wei)历史考证、形态学对比和模式产地的调查考证中,作者发现1911年H. Léveillé发表的Didymocarpus cavaleriei H.Lév.与红花大苞苣苔(Anna rubidiflora)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,综合考虑形态特征和地理分布不重叠,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《国际藻类、菌类和植物命名法规》中的规定和建议,在此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Anna rubidiflora处理为新组合的异名。 |

Abstract: |
Since the establishment of Anna 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 identification. When researching publication history, comparing morphology and investigating type locality of Anna ophiorrhizoides (Hemsl.) B.L.Burtt & R.A.Davidson and Anna rubidiflora S.Z.He, F.Wen & Y.G.Wei, we found that Didymocarpus cavaleriei H.Lév. published by H. Léveillé in 1911 and Anna rubidiflora are actually the same species, and Didymocarpus cavaleriei was treated as a synonym of Anna ophiorrhizoides. After comparing the morphological characteristics of multiple populations of Anna ophiorrhizoides and Anna rubidiflora, it was found that the difference in their morphological characteristics lies in the corolla. It is not appropriate to use differences in corolla color as boundaries for the classificatory units of species. Taking into account the morphological characteristics and non overlapping geographical distribution, it is proposed to treat Anna rubidiflora as a variety of Anna ophiorrhizoides. According to the regulations and suggestions in the 2018 International Code of Nomenclature for Algae, Fungi, and Plants (Shenzhen Code), we propose a new combination and a name at new rank——Anna ophiorrhizoides (Hemsl.) B.L.Burtt & R.A.Davidson var. cavaleriei(H.Lév.)X.X.Bai & F.Wen, and treat Anna rubidiflora as the synonym of the new combination. |
