later. The summer-vegelalion on the whole has the same 

 character as that of the hummock-desert, yet my impres- 

 sion, without having seen many locaUties of this kind, is 

 that the annual Chenopodiaceae, more especially the succu- 

 lent ones play here a minor part; this would be natural, 

 since low and therefore saline] places will rarely occur in 

 an area which is almost level.

Chenopodiaceae in the level Sand-desert indicates some diffe- 

 rence between this and the Clay-desert. As to growth-forms 

 the two resemble each other, in having low shrubs, peren- 

 nials, and ephemeral and other spring-plants. 



The most common plants in the Sand-plain desert are 

 Alhagi Camelorum, Goebelia alopeciiroides, Zijgophijlliim Eich- 

 waldii and Peganum Harmala. Fig. 16 shows a vegetation 

 where these four species take the principal part, especially 

 Goebelia with its multipinnate, white-haired leaves. 



Other Summer-plants are Kochia prostrata and stellaris.
