Abstract

Abstract Taylor, C.M., R.E. Gereau & H.H. Schmidt (2020). Some distinctive new species of Psychotria (Rubiaceae, Psychotrieae) from Madagascar. Candollea 75: 159–182. In English, English and French abstracts. Psychotria L. (Rubiaceae, Psychotrieae) is an unusually species-rich genus in Madagascar. Recent botanical explorations here have found a number of undescribed species, and some unusual morphological structures for this genus. Here ten new Psychotria species from Madagascar are formally described: Psychotria ambatovensis C.M. Taylor, Psychotria antilahimenae C.M. Taylor, Psychotria birkinshawiana C.M. Taylor, Psychotria davisiana C.M. Taylor, Psychotria eumachioides C.M. Taylor, Psychotria hamifera C.M. Taylor, Psychotria mutabilis C.M. Taylor, Psychotria notopleuroides C.M. Taylor, Psychotria palifera C.M. Taylor, and Psychotria razafimandimbisonii C.M. Taylor. Unusual morphological features of some of these species include a prostrate habit, deeply retuse leaves, and enlarged, persistent, funnelform stipules. Assessment of the conservation status of these using IUCN Red List categories finds four of them “Vulnerable” and six “Endangered”.

标题马达加斯加麻蝇属(麻蝇科，麻蝇科)若干新种

摘要Taylor，C.M.，R.E.Gereau和H.H.Schmidt（2020）。文章题目马达加斯加Psychteria属（茜草科，Psychtrieae）的一些独特新种。Candollea 75:159–182。英文、英文和法文摘要。Psychtria L.（茜草科，Psychtrieae）是马达加斯加一个物种丰富的属。最近在这里的植物学探索发现了一些未被描述的物种，以及该属一些不寻常的形态结构。这里正式描述了来自马达加斯加的十个新的Psychtria物种：ambatovensis C.M.Taylor Psychtia、antilahimenae C.M.Taylor、birkinshawiana C.M.Taylor psychtria、davisiana C.M.泰勒Psychtaria eumachioides C.M.Taylor，和Psychotria razafimandimbisonii C.M.Taylor。其中一些物种的不寻常的形态特征包括匍匐习性，叶片深凹，以及增大的、宿存的漏斗状托叶。使用国际自然保护联盟红色名录类别对这些物种的保护状况进行评估，发现其中四种为“易危”，六种为“濒危”。

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.
