摘要

摘要Wassel，A.C.和W.L.Applequist（2020）。Homalium教派的修订。尼萨（杨柳科），马达加斯加特有种。Candollea 75:1-23。英文、英文和法文摘要。Homalium教派。Nisa（Noronha ex Thouars）保释。是马达加斯加的特有种，包括四个公认的物种。提出了一种新的截面修正处理方法，并提供了识别密钥。11个物种已被确认，其中8个以前是裸花植物区系的一部分。物种复合体。新记述四种一亚种：Homalium antilahimenae Wassel&Appleq。，Homalium mandenese Wassel&Appleq。，霍马利姆·帕奇拉杜姆·瓦塞尔和阿普尔。，Homalium tenue Wassel&Appleq。，和霍马利姆·斯泰利弗亚种。Wassel&Appleq。毛状人（Sleumer）Wassel&Appleq。在物种水平上是新认识的，新组合Homalium retusum（Blume）Wassel&Appleq。进一步出版。指定了包括第二步在内的四种选择模式。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，三个分类群为“濒危”分类群，三个为“易危”分类群。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. Nisa (Salicaceae) endemic to Madagascar

Abstract Wassel, A.C. & W.L. Applequist (2020). A revision of Homalium sect. Nisa (Salicaceae) endemic to Madagascar. Candollea 75: 1–23. In English, English & French abstracts. Homalium sect. Nisa (Noronha ex Thouars) Baill. is endemic to Madagascar and has included four recognized species. A new revisionary treatment of the section is presented and an identification key is provided. Eleven species are recognized, including eight that were formerly part of the Homalium nudiflorum (DC.) Baill. species complex. Four species and one subspecies are newly described: Homalium antilahimenae Wassel & Appleq., Homalium mandenense Wassel & Appleq., Homalium pachycladum Wassel & Appleq., Homalium tenue Wassel & Appleq., and Homalium stelliferum subsp. andapense Wassel & Appleq. Homalium ciliolatum (Sleumer) Wassel & Appleq. is newly recognized at species level and the new combination Homalium retusum (Blume) Wassel & Appleq. is further published. Four lectotypes are designated including a second step. Taxonomic novelties are provided with line drawings or scans of their holotypes. Risk of extinction assessments indicate that three taxa are “Endangered” and three “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.
