The taxonomy and nomenclature of some species of the section Oxydium Benth. of Lotononis (DC.) Eckl. & Zeyh. have been revised. Diagnostic characters to distinguish between this section and the genus Crotalaria L. are briefly discussed. Crotalaria stenophylla Eckl. & Zeyh. and C. sparsiflora E. Mey. are transferred to the genus Lotononis. A new species (L carnea B-E. van Wyk) and a new subspecies (L. rostrata Benth. subsp. brachybotrys B-E. van Wyk) are described. L. namaquensis H. Bol. is treated as a subspecies of L. rostrata. The known geographical distribution of the above-mentioned species is given. Die taksonomie en nomenklatuur van enkele spesies van die seksie Oxydium Benth. van Lotononis (DC.) Eckl. & Zeyh. is hersien. Diagnostiese kenmerke om hierdie seksie van die genus Crotalaria L. te onderskei, word kortliks bespreek. Crotalaria stenophylla Eckl. & Zeyh. en C. sparsiflora E. Mey. word oorgeplaas na die genus Lotononis. ’n Nuwe spesie (L. carnea B-E. van Wyk) en ’n nuwe subspesie (L. rostrata Benth. subsp. brachybotrys B-E. van Wyk) word beskryf. L. namaquensis H.
