Abstract

Abstract: The distribution of Elytraria acaulis (Acanthaceae), the most widely distributed species of the genus in Africa, is expanded to include two further tropical West African countries, Benin and Togo. Silene melitensis (Caryophyllaceae) is reported for the first time from northern Africa. Arthrocaulon franzii (Chenopodiaceae-Amaranthaceae) is reported for the first time for Senegal. Two new combinations are proposed within Hypertelis (Molluginaceae): H. namaquensis and H. pusilla previously treated within Mollugo and Pharnaceum . The newly described Neobotrydium burundiense (Chenopodiaceae-Amaranthaceae) is synonymized with Dysphania congolana, a species native to west-central tropical Africa. The genera Neobotrydium, Ambrina and Roubieva are treated here as congeneric with Dysphania . Several new alien species are recorded for the African flora: Amaranthus standleyanus (Amaranthaceae s.str.) found in Sal Island (Cape Verde) is new for tropical Africa, and Dysphania pumilio (Chenopodiaceae-Amaranthaceae) is reported from DR Congo (new for west-central Africa). Bassia indica (Chenopodiaceae-Amaranthaceae) is cited from Kenya and Tunisia, and its invasive status is confirmed for northern Africa. Kalanchoe daigremontiana, K. delagoensis, K. × houghtonii, and K. fedtschenkoi (Crassulaceae) are ergasiophytes in Tunisia, each with a different invasion status. A key to the non-native Kalanchoe species found in Tunisia is provided.
