later. The summer-vegetation on the whole has the same 
character as that of the hummock-desert, yet my impres- 
sion, without having seen many localities 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 alopecuroides, Zygophyllum 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,
