Abstract: [Humidity and temperature are factors of primary importance influencing the altitudinal zonation patterns. "When evaluated together with morphological and chemical characters, ecological requirements have been found useful in circumscription of species." Historical factors are also important in the region. Discussion centers on Kenya in East Africa. New: Xanthoparmelia lusitana (Nyl.) comb. nov.]
