Eminium Salsola Ammothamnus 



Acanthophyllum Cousinia Oxytropis 



Agriophyllum Lachnophyllum Calligonum 



Anabasis Eremostachys Aphanoplenra 



Cornulaca Hypogomphia Cryptodiscus 



Girgensohnia Eremurns Hyalolaena 



Halanthium Rhinopetalum Psammogeton 



Halimocnemis Ammodendron Zygophyllnm 



The following genera have a wide distribution mainly 

 in warm-temperate countries (or tropical): 



Cleome Aristida Lactuca 



Cuscuta Iris 



Euphorbia Astragalus 



There still remain some large widely distributed genera: 



Artemisia Plantago Ranunculus 



Ely mus Delphinium Car um 



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 Iranscaspia 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:
