Abstract

Abstract: The delimitation of the genera Pyramidanthe and Mitrella in the tribe Uvarieae of the family Annonaceae is assessed by molecular phylogenetic analyses and morphological re-evaluation. Using up to six plastid DNA regions (matK, ndhF, rbcL exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers) and including, among others, two accessions of Pyramidanthe and five accessions of Mitrella, the resulting phylogeny shows that Pyramidanthe and Mitrella are recovered in a clade sister to the Fissistigma clade. The Pyramidanthe-Mitrella clade is composed of a trichotomy: a clade consisting of Pyramidanthe accessions and two clades containing Mitrella accessions. In combination with negligible morphological distinctions between the two genera, they are consequently merged, with 11 new combinations under the chosen name Pyramidanthe: P. beccarii, P. clementis, P. cylindrica, P. dielsii, P. elegans, P. kentii, P. ledermannii, P. mabiformis, P. schlechteri, P. sylvatica and P. tiwiensis. The names M. dielsii (the basionym of P. dielsii) and P. rufa (a heterotypic synonym of P. prismatica) are lectotypified. Pyramidanthe s. lat. possesses the following diagnostic traits: usually indistinct secondary leaf veins with a brochidodromous to brochidodromous-eucamptodromous venation, a reticulate tertiary leaf venation, axillary inflorescences, presence of a basal excavation on an inner side of each outer petal, and inner petals that are much smaller than the outer petals and cohering marginally at anthesis.

紫锥花与紫锥花的统一:分子系统发育和形态一致性，以及紫锥花的新组合

摘要：通过分子系统发育分析和形态学重新评价，对番荔枝科乌瓦里科Pyramidanthe属和Mitrella属的划分进行了评价。使用多达六个质体DNA区域（matK、ndhF、rbcL外显子；trnL内含子；psbA-trnH、trnL-trnF基因间间隔子），包括两个Pyramidanthe材料和五个Mitrella材料，由此产生的系统发育学表明，Pyramidandre和Mitrella在Fissistigma分支的姐妹分支中恢复。锥虫Mitrella分支由三分法组成：一个由锥虫材料组成的分支和两个包含Mitrella材料的分支。由于这两个属之间的形态差异可以忽略不计，因此它们被合并，有11个新的组合被命名为Pyramidanthe：P.beccarii、P.clementis、P.cylindrica、P.dielsii、P.elegans、P.kentii、P.ledermannii、P.mabiformis、P.schlechteri、P.sylvatica和P.tiwiensis。M.dielsii（P.dielsii的basionym）和P.rufa（P.prismatica的一个异型异名）的名称被选型。金字塔花具有以下诊断特征：通常不明显的二级叶脉，具有布罗氏至布罗氏真两性叶脉，网状的第三级叶脉、腋生花序，每个外层花瓣内侧有基部凹陷，内部花瓣比外部花瓣小得多，在开花时边缘粘着。引文：Bangkonate R.、Damthongdee A.、Baka A.、Aongyong K.和Chaowasku T.2021：Pyramidanthe和Mitrella（番荔枝科、乌瓦里科）统一：分子系统发育和形态一致性，在Pyramidathie中有新的组合Willdenowia 51:383-394。该记录的版本于2021年12月xx日首次在线发布，随后将纳入2021年12月刊。

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).
