158 DISTRIBUTION OF PLANTS ON SOILS. 



belt of cedar -juniper, and towards its upper part, 

 grow species of Gnaphalium, Campanula, Cerinthe, 

 Sideritis, Alchemitta, Scorzo?iera, and Santolina, 

 with which we do not meet much lower down. 

 Here are also Prunus prostrata, Ernodea alpina, 

 Digitalis ferruginea, Aubrietia deltoidea, and pecu- 

 liar species of Aretia, Coldiicum, and Crocus. 



Throughout our journeys we paid careful at- 

 tention to the relations of the distribution of the 

 indigenous plants to the soil in which they 

 grew. The simple features of the geology of 

 Lycia and the constancy of mineral character of 

 the various rocks over considerable tracts of 

 country enabled us to do this with facility and 

 precision. Whilst each of the several regions 

 into which we have attempted to divide the vege- 

 tation of Lycia considered as to its vertical distri- 

 bution, presented a general character of its own, 

 that character was locally varied according as 

 the foundation rock was the hard appennine 

 limestone, the sandy rocks which cap it, the 

 soft tertiary marls and conglomerates, or the 

 brittle and barren serpentine, the only igneous 

 rock in this part of Asia Minor which occupies 

 sufficient space to affect the flora. 



At almost any distance we could distinguish
