Saharanthus M.B. Crespo & M.D. Lledo nom. nov. is proposed on the basis of the illegitimate Lerrouxia Caball., for a woody species from western Sahara, also known as CabaUeroa Font Quer. Ceratolirnon M.B. Crespo & M.D. Liedo gen. nov. is proposed for a group of five taxa (four species and one additional variety) of dwarf shrubs with horned spikelets, which show a disjunct distribution on the edges of the Sahara Desert. This latter name applies to most species formerly placed in the illegitimate Bubania. Types are indicated for all taxa, and identification keys are also presented. 收起
