4. The area of the Moving-Sands. 
This stretches mainly south-east and east from the Aral 
Sea. The vegetation is more luxuriant than in the other 
areas, and is at the same time more interesting and richer 
in rare and strange plant-forms. In spring it looks quite 
like a garden. The dunes are covered with bushes of Calli- 
gonum, Halimodendron, Saxaul, Tamarix, Salsola etc. Some 
of these are also present in other formations, but reach here 
their fullest development, “so that this territory may justly 
be termed the forest of the desert-flora”.') 
Of the 501 species of Phanerogams characteristic for the 
sand-flora, 16,16 per ct. are trees and shrubs. The propor- 
tion of perennials and biennials to annuals is as 1: 0,75. 
235 species belong exclusively to the dunes. The sand-flora 
includes: 
26,9 per ct. of Ranunculaceae of thew hole area.

In addition to Cruciferae and Papilionaceae, Borragineae 
and Polygonaceae are also plentiful. Borszczow mentions 
amongst the Cruciferae: Dontostemon (several species) Strep- 
toloma, Spirorhynchus, Pachypterygium, Cithareloma, Lachno- 
*) This simile has justly been contradicted by KorschHinsky and Tan- 
FILJEW. Yet Lipsky (1911) is of the opinion that some large tracts of 
Saxaul — but only of this — may rightly be named forests, the trees 
being big and thick and giving a considerable amount of ground-litter.
