436 APPENDIX G. 



extends, with local peculiarities, from Persia and Belutschistan 

 to the Atlantic Islands. Out of 248 genera represented in the 

 Flora of these valleys there is not one which is not common to 

 other portions of the Mediterranean region, and one only {Mon- 

 anthes) is confined to the Great Atlas and the Canary and Cape 

 de Yerde Islands, all the others being types more or less widely 

 spread. Further than this, the proportion borne by each of the 

 prevailing natural orders to the whole vegetable population is 

 pretty nearly the same that we are accustomed to find in the 

 mountain regions of the Mediterranean region. 



The materials for a comparison are unfortunately yet incom- 

 plete as regards many of the mountain districts which are best 

 fitted for the purpose. The Flora of the Lesser Atlas of Al- 

 geria, as well as that of the rest of the French possessions in 

 Africa, will be fully known only on the appearance of the im- 

 portant work promised by M. Cosson. The Flora of Spain by 

 MM. Willkomm and Lange is yet unfinished, and there is the 

 further difficulty that those authors have admitted a large num- 

 ber of plants to the rank of species which many botanists 

 reckon only as varieties. M. Boissier's great work, the ' Flora 

 Orientalis,' is also unfinished, and no adequate m.aterials exist 

 for compiling lists of the plants of the Greek moimtains, of 

 those of Asia Minor, or of the Lebanon chain, all of which 

 would afford interesting materials for comparison. In the fol- 

 lowing table I have taken for comparison the Flora of the 

 Sierra Nevada, with the neighbouring mountains of the ancient 

 kingdom of Granada above the level of about 800 metres, com- 

 piled from Boissier's ' Voyage botanique dans le Midi de 

 I'Espagne; ' that of the Bulgardagh (the principal group of the 

 CUician Taurus), from a list published by M. Pierre de 

 Tchihatcheff in the ' Bvilletin of the French Botanical Society ; ' 

 that of Dalmatia, from Visiani's excellent ' Flora Dalmatica ; ' 

 and that of the southern slopes of the chain of the Alps 

 from Nice to the Karst, formed by myself from all available 

 sources. 



In the same table I have introduced, for the purpose of fur- 

 ther comparison, separate columns for the middle and superior 

 regions of the Great Atlas valleys, and in connection with the 

 last I have added in a separate column the results for the higher 

 zone of the Sierra Nevada. Under each heading I have stated
