Abstract: | The material of Micromeria s.s. ( M. sect. Micromeria ) from tropical to southern Africa and the Arabian Peninsula is revised. The endemic Ethiopian M. unguentaria Schweinf. is retained as a species, while the other African and Arabian material of Micromeria is included in M. imbricata (Forssk.) C. Chr. M. imbricata is divided into the following three varieties: var. imbricata , which is very polymorphic, widespread in the African highlands, and also occurs in Arabia; var. rhodesiaca (Elly Walther & K.H. Walther) Ryding, which occurs in the highlands of Malawi, Mozambique and Zimbabwe; and var. villosa (Elly Walther & K.H. Walther) Ryding, which occurs in montane to alpine areas of Ethiopia and East Africa. Discontinuities in the variation within var. imbricata , observed at some localities, are suggested to be a result of partial autogamy. Problems with delimitation between M. imbricata , the East Asiatic M. biflora (Buch.-Ham. ex D.Don) Benth. and some Mediterranean species are discussed. © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society , 2007, 155 , 427–446. |
