摘要

摘要/ Abstract摘要:Fridericia是新热带藤本植物中一个引人注目的属，有7个系60种，广泛分布于新热带干湿环境。作为正在进行的属分类研究的一部分，我们提供了两个分支的分类修订:(1)“acrodroous venation”分支和(2)“Piriadacus”分支。前者的特点是1或2小叶的叶，有顶凸脉，管状花萼和皮质的果实，边缘稍凸起。后者由红色，粉红色或橙色，管状花冠和外露或近外露的花药来识别。我们在每个谱系中识别出两个物种，并提供了鉴定密钥、形态描述、插图、分布图以及对分布、物候、保护状况和分类学的评论。我们建议13 lectotypification名字:Arrabidaea brachypoda var. acuminata, a brachypoda var. attenuata则,a brachypoda var. firma, a brachypoda var. induta, a brachypoda var. rigida, a platyphylla var. lasiorrhachis, a platyphylla var. puberula,紫葳brachypoda var. firmula, b . erubescens var. breviflora, b . erubescens var. subtruncata, b . regnelliana Cuspidaria erubescens var. glabrescens和Petastoma simplicifolium。我们进一步纠正了短花木和短花木的分型，并提出了两个新的白桦同义名(即celastroides和violacea)。引用本文:Kaehler M. & Lohmann L.

Taxonomic revisions in Fridericia (Bignonieae, Bignoniaceae) I: the “Acrodromous venation” and “Piriadacus” clades

Abstract: Fridericia is a conspicuous genus of neotropical lianas, with 60 species distributed among seven lineages that are broadly distributed through the neotropics in both dry and wet environments. As part of ongoing taxonomic studies of the genus, we provide taxonomic revisions of two clades: (1) the “Acrodromous venation” clade and (2) the “Piriadacus” clade. The former is characterized by 1- or 2-foliolate leaves with acrodromous venation, tubular calyces and coriaceous fruits with slightly raised edges. The latter is recognized by the red, pink-reddish or orange, tubular corolla and exserted or sub-exserted anthers. We recognize two species in each lineage and provide identification keys, morphological descriptions, illustrations, distribution maps and comments on the distribution, phenology, conservation status and taxonomy. We propose the lectotypification of 13 names: Arrabidaea brachypoda var. acuminata, A. brachypoda var. attenuata, A. brachypoda var. firma, A. brachypoda var. induta, A. brachypoda var. rigida, A. platyphylla var. lasiorrhachis, A. platyphylla var. puberula, Bignonia brachypoda var. firmula, B. erubescens var. breviflora, B. erubescens var. subtruncata, B. regnelliana, Cuspidaria erubescens var. glabrescens and Petastoma simplicifolium. We further correct the typification of B. erubescens var. breviflora and B. erubescens var. subtruncata and propose two new synonyms for F. platyphylla (i.e. A. celastroides and B. violacea).

期刊介绍： Willdenowia is an international peer-reviewed journal publishing original research articles in English from the entire fields of plant, algal and fungal systematics, covering the evolution, taxonomy and nomenclature of these organisms as well as related fields such as floristics and plant geography. Articles on phylogeny and molecular systematics are especially welcome, as are review articles. Descriptions of new taxa may be considered, but only if supported by robust evidence. Narrowly regional studies of widespread taxa, routine typifications, checklists and new floristic records are generally not considered (excluding contributions to the Euro+Med-Checklist Notulae). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, in the Berlin herbarium (B).
