摘要
[摘要]Hanes, m.m., G.E. Schatz & M.W. Callmander(2020)。马达加斯加的Humbertianthus属和Macrostelia属向木槿属(锦葵科)的转移及四个新种的描述。烛台学报75:193-202。英文,英文和法文摘要。Macrostelia Hochr属的两个马达加斯加种。(Malvaceae)转移到Hibiscus L.,并提出了两个新的组合:Hibiscus calyculatus (Hochr.)。M. Hanes, ge . Schatz & Callm。和芙蓉(Hochr.)M. Hanes & ge . Schatz & Callm。单型属:黄花属。和它的单一种Humbertianthus cardiostegius Hochr。定义为一个处于芽期的分类单元,代表木槿(Hibiscus laurinus Baill)未开放的花丛。最近从马达加斯加东部潮湿森林中采集的几个植物标本代表了四种新的限制范围物种:ambanitazensis M. Hanes & G.E. Schatz, analalavensis M. Hanes & G.E. Schatz, ankeranensis M. Hanes & G.E. Schatz, vohipahensis M. Hanes & G.E. Schatz。每一种新种都有野外照片记录,并介绍了它们的地理分布。对所讨论的七个物种的灭绝风险评估表明,三个分类群受到“极度濒危”的威胁,四个分类群受到“最不关注”的威胁。
Transfer of the Malagasy genera Humbertianthus and Macrostelia to Hibiscus (Malvaceae) with description of four new species
Abstract Hanes, M.M., G.E. Schatz & M.W. Callmander (2020). Transfer of the Malagasy genera Humbertianthus and Macrostelia to Hibiscus (Malvaceae) with description of four new species. Candollea 75: 193–202. In English, English and French abstracts. Two Malagasy species of the genus Macrostelia Hochr. (Malvaceae) are transferred to Hibiscus L. and two new combinations are proposed: Hibiscus calyculatus (Hochr.) M. Hanes, G.E. Schatz & Callm. and Hibiscus involucratus (Hochr.) M. Hanes & G.E. Schatz & Callm. The monotypic genus Humbertianthus Hochr. with its single species Humbertianthus cardiostegius Hochr. was defined as a taxon in its bud stage and represented unopened flowering collections of Hibiscus laurinus Baill. Several recent herbarium collections from the eastern humid forest of Madagascar represent four new restricted range species: Hibiscus ambanitazensis M. Hanes & G.E. Schatz, Hibiscus analalavensis M. Hanes & G.E. Schatz, Hibiscus ankeranensis M. Hanes & G.E. Schatz, Hibiscus vohipahensis M. Hanes & G.E. Schatz. Each of the new species are documented by field photographs and their geographic distribution is presented. Risk of extinction assessments of the seven species discussed indicate three taxa are threatened as “Critically Endangered”, and four are “Least concern”.
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.
