OCTOBEK 1 TO DECEMBER 31, 1910. 21 



28942 to 29012— Continued. 



28972. Capparis spinosa L. Caper. 



From near Langar, Zerafshan Valley, Samarkand, Turkestan. "(No. 1372a, 

 July 13, 1910.) The well-known caper plant, growing on the driest of sun- 

 burned mountain slopes and having roots that penetrate yards into the soil 

 and between cracks in rock ledges. Roots sent from the Caucasus under No. 

 783 (S. P. I. No. 28126), which number see for further remarks." {Meyer.) 



28973. Salsola arbuscula Pallas. 



From Chartchui, Turkestan. "(No. 1373a, June 18, 1910.) A shrub of 

 peculiar appearance, having no leaves but instead long, slender, green, drooping 

 branches. Is used with much success in the sand-binding and desert-reclama- 

 tion work along the central Asian railroads. Recommended for the dry and 

 hot sections of the United States for various purposes: (1) For its sand-binding 

 properties; (2) as an ornamental park and garden shrub; (3) as a fuel supply 

 in desert regions. 



"These seeds should be sown out in the fall and kept moist until the young 

 plants appear above ground; after that they should be watered sparingly. 



"Obtained from Mr. W. A. Paletsky, in charge of sand-binding operations 

 along the railroads in central Asia." (Meyer.) 



28974. Calligonum caput-medusae Schrenk. 



From Chartchui, Turkestan. "(No. 1374a, June 18, 1910.) A shrub of very 

 much the same appearance as the preceding number, only flowering quite 

 beautifully toward the end of May and early June. Strongly recommended, 

 therefore, as an ornamental park and garden shrub in desert regions where high 

 summer temperatures prevail, but where the mercury does not drop below zero 

 F. See preceding number for further remarks." (Meyer.) 



28975. Calligonum aphyllum (Pall.) Guerke. 



From Chartchui, Turkestan. "(No. 1375a, June 18, 1910.) A tall shrub like 

 the preceding, but of more arborescent growth and somewhat less ornamental; 

 otherwise all remarks made on preceding numbers apply also to this one." 

 (Meyer.) 



28976. Haloxylon ammodendron (C. A. Meyer) Bunge. Saxaul. 

 From Chartchui, Turkestan. "(No. 1376a, June 18, 1910.) The famous 



saxaul tree, one of the chief fuel supplies of the deserts and oases in central 

 Asia. The wood, which is exceedingly heavy and compact, retails at 20 to 

 25 kopecks a pood (40 pounds). For possible uses and cultural remarks see 

 preceding numbers; see also remarks under No. 1303a (S. P. I. No. 27802)." 

 (Meyer.) 



28977. Carex physodes Bieb. 



From Chartchui, Turkestan. "(No. 1377a, June 18, 1910.) A rare species 

 of sedge, native of the desert, used in sand-binding work along the central 

 Asian railroads. To be tested for similar purposes in the arid sections of the 

 southwestern United States; also, as a possible lawn sedge in the same regions. 

 Obtained like the preceding numbers." (Meyer.) 



28978. Rosa xanthina Lindl. Rose. 

 From near Kulikalan, Samarkand, Turkestan. " (No. 1378a, July 10, 1910.) 



A very spiny, shrubby rose, bearing in early summer an abundance of small, 

 deep butter-yellow roses. Found on stony, sterile mountain slopes and in 

 ravines at altitudes of 6,000 to 9,000 feet. Recommended for hybridization 

 work to create perfectly hardy yellow roses and as an ornamental garden shrub 

 for the northern United States." (Meyer.)
