The following genera have a wide distribution mainly 

 in warm -temperate countries (or tropical): 



Lactuca 



There still remain some large widely distributed genera: 



Artemisia 

 Elymus 



Plantago 

 Delphinium 



Ranunculus 

 Carum 



These genera are distributed over so large an area that 

 only a closer study could elucidate where the Transcaspian 

 endemic species of these genera have their nearest relatives. 



Leaving out of account the 6 genera last-named which 

 are represented by 9 endemic species, all the rest of the 

 plant genera containing endemic species in Transcaspia have 

 their main distribution towards the South, most of them in 

 the Mediterranean countries and in Western Asia. This is 

 an indication that the flora of Transcaspia is closely allied to 

 the flora of these countries. 



The natural orders which contain endemic species can 

 be ascertained by reference to the list of plants (pp. 138 — 158). 

 More than one example of endemism is to be found in the 

 following families:
