"Desert landscape with 'old specimens of Populus 
pruinoea in the background and tamarisk mounds in 
between." J torn photograph by Mr. Frank II* Meyer, 
near Kuldsch?*, Chinese Turkestan, February, 1911., 
Mr-. Meyer further describes this tree: "A species of 
desert poplar,-, called 'Thai Tograk'. Occurring in 
big groves in sandy and alkaline deserts mostly 
intermixed wath Populus diversifol ia(See next half- 
tone), to which it bears great resemblance in 
general habits. The wood is used in the same way as 
that of P. di vers if o 1 i h , except that us this species 
in general ooes not grow so large, one cannoi manu- 
facture troughs or barrels from it; it is, however, 
said that, this wood is harder and more lasting. This 
poplar will be able to stand more intense heat and 
drought,- but slightly less severe cold than P. di- 
vers if olia." Nos. 30230 and 30921.
