Keys to African Solanum

Knapp S. Vorontsova MS, Särkinen T. (2019) Dichotomous keys to the species of Solanum L. (Solanaceae) in continental Africa, Madagascar (incl. the islands of Réunion, the Comoros and the Seychelles), Macaronesia, and the Cape Verde Islands. PhytoKeys (in press). Abstract. Solanum L. (Solanaceae) is one of the largest genera of angiosperms and presents difficulties in identification due to lack of regional keys to all groups. Here we provide keys to all 135 species of Solanum native and naturalised in Africa (as defined by World Geographical Scheme for Recording Plant Distributions): continental Africa, Madagascar (incl. the islands of Réunion, the Comoros and the Seychelles), Macaronesia, and the Cape Verde Islands. Some of these have previously been published in the context of monographic works, but here we include all taxa. The paper is designed to be used in conjunction with the web resource Solanaceae Source (www.solanaceaesource.org) and hyperlinks provide access to online descriptions, synonymy and images (where available) of each species. All taxa treated and specimens seen are included in searchable Supplementary materials files (also provided on NHM Data Portal).
