摘要

背景和目的-描述了刚果民主共和国的一个新物种魔芋（天南星科），该物种与为非洲花（Flore D‘Afrique centrale）准备家族治疗有关。卢旺达首次记录到另一个物种。方法——采用标准的植物标本馆做法。关键结果——杜姆博伊魔芋（Amorphophallus dumboi sp.nov.）与马齿苋（A.margretae）有亲缘关系。讨论了这些物种之间的差异，并给出了分类群的分布图。这两个物种都被限制在艾伯丁裂谷的范围内，并被初步评估为极度濒危物种。马约伊魔芋是卢旺达首次被记录在案。该分类单元最初被描述为a.calabaricus的一个亚种，在这里被提升到特定的级别。

A new species of Amorphophallus (Araceae) from Eastern D.R. Congo, and a new record of the genus from Rwanda

Background and aims – A new species of Amorphophallus (Araceae) is described from D.R. Congo in connection with preparing the family treatment for the Flore d’Afrique centrale. Another species is recorded for the first time from Rwanda. Methods – Standard herbarium practices were applied. Key results – Amorphophallus dumboi sp. nov. is related to A. margretae. The differences between these species are discussed and distribution maps for the taxa are presented. Both species are range-restricted in the Albertine Rift and preliminarily assessed as Critically Endangered. Amorphophallus mayoi is for the first time recorded for Rwanda. The taxon, originally described as a subspecies of A. calabaricus, is raised here to specific rank.

期刊介绍： Plant Ecology and Evolution is an international peer-reviewed journal devoted to ecology, phylogenetics and systematics of all ‘plant’ groups in the traditional sense (including algae, cyanobacteria, fungi, myxomycetes), also covering related fields. The journal is published by Meise Botanic Garden and the Royal Botanical Society of Belgium.
