摘要

摘要Applequist，W.L.（2020）。Homalium教派的修订。杜鹃花（杨柳科），马达加斯加特有种。Candollea 75:245-268。英文、英文和法文摘要。Homalium教派。Rhodonisa（Tul.）Sleumer是马达加斯加的特有种，包括三个公认的物种。提出了一种新的截面修正处理方法，并提供了识别密钥。已鉴定出12种，其中7种为新描述：Homalium analavelonae Appleq。，Homalium ihoshense Appleq。，胡麻。，费城人。，伪cemosum Appleq。，Homalium rakotovaoi Appleq。，和Homalium vohitsiandrianese Appleq。指定了两种选型。分类学上的新奇事物被提供了它们的正模线图或扫描图。灭绝风险评估表明，有两个分类群为“极度濒危”，一个为“濒危”，四个为“易危”。偶尔会观察到杂交现象。有些标本无法分类，可能存在其他未被识别的物种。

A revision of Homalium sect. Rhodonisa (Salicaceae) endemic to Madagascar

Abstract Applequist, W.L. (2020). A revision of Homalium sect. Rhodonisa (Salicaceae) endemic to Madagascar. Candollea 75: 245–268. In English, English & French abstracts. Homalium sect. Rhodonisa (Tul.) Sleumer is endemic to Madagascar and has included three recognized species. A new revisionary treatment of the section is presented and an identification key is provided. Twelve species are recognized, of which seven are newly described: Homalium analavelonae Appleq., Homalium ihosyense Appleq., Homalium megaphyllum Appleq., Homalium phillipsonii Appleq., Homalium pseudoracemosum Appleq., Homalium rakotovaoi Appleq., and Homalium vohitsiandrianense Appleq. Two lectotypes are designated. Taxonomic novelties are provided with line drawings or scans of their holotypes. Risk of extinction assessments indicate that two taxa are “Critically Endangered”, one is “Endangered” and four “Vulnerable”. Occasional hybridization is observed. Some specimens are not classifiable and it is possible that other unrecognized species exist.

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.
