Los líquenes silicícolas de la Sierra del Cabo de Palosestudio florístico fitosociológico y ecológico

Abstract

Study of the lichen flora and vegetation of the eastern end of the Sierra de Cartagena (SE of Spain). These abrupt and dry hills of more or less consistent schists give shelter to a lichen flora rich in thermophilic species (xeromacaronesis species). Some of them find here their northern limit: Acarospora charidema, Rhizocarpon lusitanicum, Ramalina bourgeana, R. clementeana, Dimelaena radiata. Some communities have been recognized: Xantorietum resendei diploicietosum subas. nov. and Acarosporetum charidemi, on sunny surfaces, Pertusarietum-gallicae, on shady surfaces, a Com. of Dirina schistosa and Roccella phycopsis, on overhangs, and a Com. of Solenopso ra holophaea, on tender, shady and eutrophic schists. A cathalogus of the 61 species found contains morphologic, microscopic, iconographic and ecologic information about a good deal of them.
