摘要

[摘要]STONE, R.D.(2020)。文章题目马达加斯加绵木属新种:TEF植物标本馆珍品。烛台学报75:219-239。英文，英文和法文摘要。漆木属(Melastomataceae, Olisbeoideae)是分布广泛的古热带森林灌木和小树属，是马达加斯加木本植物种类最丰富的十大属之一。在之前的研究中，jacques - f lix在岛上发现了78种Memecylon，其中所有物种都是当地特有的，大多数只在一两个地点发现。本文主要根据从fof . fif . fa植物标本馆(TEF)外借的资料，描述和说明了马达加斯加的9个新种(包括:Memecylon planatum r.d.stone、Memecylon convergens r.d.stone、Memecylon fofifa r.d.stone、Memecylon longipetiolatum r.d.stone、Memecylon paraxenum r.d.stone、Memecylon potamecylon r.d.stone、Memecylon pseudogaleatum r.d.stone、Memecylon subchartaceum r.d.stone和Memecylon unguulare r.d.stone)。根据世界自然保护联盟红色名录的分类和标准，对每个物种的保护状况进行临时评估。考虑到马达加斯加广泛的人为砍伐森林，人们必须考虑到扁棉棉、副棉棉和伪galeatum棉棉已经灭绝的可能性，因为这三个物种在过去的50-60年里没有被重新发现。目前正在对马达加斯加的Memecylon进行全面的分类修订。

New species of Memecylon (Melastomataceae) from Madagascar: treasures of the TEF Herbarium

Abstract STONE, R.D. (2020). New species of Memecylon (Melastomataceae) from Madagascar: treasures of the TEF Herbarium. Candollea 75: 219–239. In English, English and French abstracts. Memecylon L. (Melastomataceae, Olisbeoideae) is a widespread paleotropical genus of forest shrubs and small trees, and is one of the ten most species-rich genera of woody plants in Madagascar. In a previous treatment, Jacques-Félix recognized 78 species of Memecylon on the island, of which all are endemic and most are known from just one or two sites. The present work describes and illustrates nine new species of Memecylon from Madagascar (including Memecylon complanatum R.D. Stone, Memecylon convergens R.D. Stone, Memecylon fofifa R.D. Stone, Memecylon longipetiolatum R.D. Stone, Memecylon paraxenum R.D. Stone, Memecylon potamicum R.D. Stone, Memecylon pseudogaleatum R.D. Stone, Memecylon subchartaceum R.D. Stone, and Memecylon unguiculare R.D. Stone), based mainly on material received on loan from the FO.FI.FA Herbarium (TEF). The conservation status of each species is provisionally assessed in accordance with the IUCN Red List Categories and Criteria. Given the extensive anthropogenic deforestation of Madagascar, one must consider the possibility that Memecylon complanatum, Memecylon paraxenum, and Memecylon pseudogaleatum are already extinct since these three species have not been recollected within the last 50–60 years. Work is ongoing towards a comprehensive taxonomic revision of Memecylon in Madagascar.

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.
