摘要

摘要Gautier，L.，C.G.Boluda，R.Randrianaivo和Y.Naciri（2022）。马达加斯加特有的高度多样化的Capurodendron属的另外两个新种（皂科）。Candollea 77:119-126。英文、英文和法文摘要。在对马达加斯加皂科物种进行修订的过程中，两个来自干燥森林的新种属于高度多样化的特有属Capurodendron Aubrév。被发现。第一个，C.mikearum L.Gaut。&根据对西南地区一个物种复合体的遗传和形态学分析，早期被假设为杂交种的Boluda是一个没有任何杂交信号的有效物种。第二种，C.namorokense L.Gaut。&Boluda在同一物种的分支中占据基础位置。它在形态上明显不同，地理位置遥远，迄今为止只在马达加斯加西北部被发现。这两个物种都通过线条图和现场照片进行了描述和说明。使用国际自然保护联盟红色名录标准进行的初步保护评估表明，这两个物种都受到了威胁（分别为EN和CR）。于2022年1月6日收到。于2022年4月27日接受。于2022年6月1日首次在线发布。

Two further new species in the highly-diverse Malagasy endemic genus Capurodendron (Sapotaceae)

Abstract Gautier, L., C.G. Boluda, R. Randrianaivo & Y. Naciri (2022). Two further new species in the highly-diverse Malagasy endemic genus Capurodendron (Sapotaceae). Candollea 77: 119–126. In English, English and French abstracts. During the course of a revision of the Malagasy species of the family Sapotaceae, two new species from the dry forest belonging to the highly-diverse endemic genus Capurodendron Aubrév. were discovered. The first one, C. mikearum L. Gaut. & Boluda, earlier hypothesised to be a hybrid, emerged as a valid species without any hybrid signal, based on a combination of genetic and morphological analyses of a species complex from the southwestern region. The second species, C. namorokense L. Gaut. & Boluda, occupies a basal position in the same species clade. It is clearly morphologically distinct and geographically distant, so far only being known from northwestern Madagascar. Both species are described and illustrated by line drawings and field photographs. Preliminary conservation assessments using the IUCN Red List criteria indicate that both species are threatened (EN and CR, respectively). Received on January 6, 2022. Accepted on April 27, 2022.

期刊介绍： Candollea is an international peer-reviewed journal that publishes original scientific papers, preferably in English but also in French. Spanish language manuscripts will be evaluated only if linked to scientific projects involving the Conservatoire et Jardin botaniques de Genève. Successful submissions will be in the fields of evolution, molecular systematics, morphology-anatomy, nomenclature, taxonomy, or vegetation analyses of plants. Reviews and articles on the history of botanical collections are welcome. New distribution records lacking pertinent analyses will not be considered. Manuscripts dealing with nomenclature alone will be considered only if clearly related to the Geneva library or herbarium (G). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, at G.
