66 ON THE BOTANICAL GEOGRAPHY Of THE 



The Flora of New and Old Castile, and or* 

 a part of Estremadura, is a singular and very 

 distinct Flora from the rest. The plains of sand 

 and gypsum, in these provinces, produce a medley 

 of peculiar plants most exclusively their own. 

 Lceflingia, Queria, Minuartia, &c. are well known J 

 but a great number of them, even of those in the 

 neighbourhood of Aranguez, are yet undescribed. 

 The chain of mountains have also many that are 

 peculiarly their own, although not in proportion 

 to the plains. The excessive heat of the summer, 

 the intense cold of the winters, the shadeless plains, 

 and the gypseous soil, considered elsewhere as 

 phenomena, are here in the order of nature. 



The Flora of Valencia, especially that, of the 

 range of the calcareous mountains, which run 

 through the whole of that province and part of 

 Catalonia, has many peculiarities-. The species 

 of Teucrium are here in abundant diversity, as 

 also Ciscus, Sideritis, &c Of Cistus, however, 

 only the smaller species are found, the larger 

 ones belong to the hot sandy heaths of Andalusia 

 and Portugal,
