摘要

背景和目的——对卢旺达姜科进行了修订，并提供了非洲姜属植物的三个新记录（A.corrorima、A.danielii、A.zambesiacum）。一个先前记录的物种，A.alboviolaceum，必须从卢旺达植物区系中排除。描述了卢旺达和布隆迪的Reneamia的两个新种，它们与中央非洲花的家族治疗有关。材料和方法——采用野外工作和标准植物标本馆做法。关键结果——Reneamia timmiorum sp.nov.与金鸡纳R.cincinnata和卡氏R.cabrae相似，卡氏R.susannae sp.nov..与非洲R.africana和dewevrei相似。讨论了这些物种之间的差异，并给出了新分类群的分布图。Reneamia timmiorum被评估为最不受关注（LC），而R.susannae katziae被评估为濒危（EN）。

The family Zingiberaceae in Rwanda with description of two new species of Renealmia

Background and aims – The Zingiberaceae of Rwanda are revised, and three new records of Aframomum species (A. corrorima, A. daniellii, A. zambesiacum) are provided. One previously recorded species, A. alboviolaceum, has to be excluded from the Flora of Rwanda. Two new species of Renealmia are described from Rwanda and Burundi in connection with the preparation of the family treatment for the Flore d’Afrique centrale. Material and methods – Field work and standard herbarium practices were applied. Key results – Renealmia timmiorum sp. nov. is similar to R. cincinnata and R. cabrae, and R. susannae-katziae sp. nov. is similar to R. africana and R. dewevrei. The differences with these species are discussed and distribution maps for the new taxa are presented. Renealmia timmiorum is assessed as Least Concern (LC), while R. susannae-katziae is assessed as Endangered (EN).

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.
