On this soil Reaumuria fruticosa was characteristic, a low bush 
with closely set minute leaves covered with salt-crystals. Some 
other species occurred on some small dunes, but these only 
appeared one at a time on the stony soil. (See chap. 11). The 
following Lichens were found on stones: Sarcogyne perileuca, 
Placodium Paulsenü, Acarospora interrupta. At Dana Sher Kala 
not far from this place, there was a stony gravel plain with 
very scattered small bushes of Salsola rigida behind which 
hillocks of sand had drifted; this was the only species. 
At Ak-Yar (also on the Amu Darya) there is an undul- 
ating plain of loess with splintered pieces of clay-slate and 
knolls of the same rock in situ. The following plants were 
scattered about, approximately 3 paces apart: Salsola rigida 
and Arbuscula, Reaumuria oxiana, Saxaul and rarely Lycium 
ruthenicum; all were stunted shrubs less than half a metre 
high. The herbaceous species included Salsola carinata, Suaeda 
sp. and Lepidium obtusum. Depressions with a stiff fissured 
clay were devoid of plants or bore only a few halophytes 
(Halocnemum, Halimocnemis). 
At Pitnjak there was a gravel plain with Peganum Har- 
mala, Convolvulus eremophilus and Anabasis salsa, very scattered. 
At Kisel-Yi also situated south of Chiwa, we found hard 
clay hills with many white stones, quite bare except in the 
depressions where there were scattered plants of Halimocne- 
mis macranthera (an annual summer-plant with thick leaves) 
Salsola rigida, low Saxaul bushes, Artemisia, Alhagi Camelo- 
rum. The last alone crept up the hillside here and there. 
Near Andidshan (Ferghana), very stony loess about a foot 
thick formed a layer over stones and gravel. Here grew 
(May 27) Tamarisks not more than a metre high, Alhagi 
Camelorum, Crambe orientalis (?), the thorny and silverhaired 
undershrub Convolvulus fruticosus, Echinops sp., Astragalus 
sp., etc.; the visit to this locality was a very brief one. 
Other localities were observed where the soil was rock 
in situ or stone, but as these were covered by sand, partly 
shifting, and as it seemed to me that there the sand was 
mainly responsible for the character of the vegetation, they are 
not included here.
