Abstract

Greenwayodendron(Annonaceae) is a tropical African genus of trees occurring mainly in rain forests. Until recently,Greenwayodendroncontained only two species:Greenwayodendronoliverifrom West Africa andGreenwayodendronsuaveolensfrom Central and East Africa.Genetic data, using chloroplast haplotypes and nuclear microsatellites as well as morphometric analyses, provided important information on the delineation of species.Greenwayodendronnow contains six species, including two new species (GreenwayodendronglabrumLissambou, Hardy & Couvreur,sp. nov.andGreenwayodendronlittoraleLissambou, Dauby & Couvreur,sp. nov.). Greenwayodendronsuaveolensvar.gabonica and Greenwayodendronsuaveolenssubsp.usambaricum are recognised as distinct species:Greenwayodendrongabonicumcomb. nov.andGreenwayodendronusambaricumcomb. nov., respectively. A key, detailed descriptions of morphology and geographic distributions, as well as notes on their ecology and uses are presented for all species. Preliminary conservation assessments following IUCN criteria are also provided. Two species are preliminarily identified as threatened, one as Endangered and one as Vulnerable.
