| Abstract: | Chromosome numbers of 21 taxa in Lobelia L. and Cyphia Berg, are reported, the majority being new records. 2n = 18 in Cyphia is a new generic report. The new species Lobelia paludigena Thulin (Zaire), L. kundelungensis Thulin (Zaire), L. cheranganiensis Thulin (Kenya) and L. corniculata Thulin (Swaziland and Natal) are described. The distributions of these species, as well as of L. thermalis Thunb., are mapped. L. kalobaënsis E. Wimm. ex Thulin is validated. The new combinations L. trullifolia Hemsl. ssp. delicatula (Compton) Thulin and L. flaccida (Presl) A. DC. ssp. gnmvikii (T. C. E. Fries) Thulin are made. Typifications are provided for the following names: L. stuhlmannii Schweinf. ex Stuhlm., L. gregoriana Bak. f., L. fervens Thunb., L. anceps L. f. and L. depressa L. f. |
