PLANT MATERIAL INTRODUCED 



72453 to 72570— Continued. 



72556. Rhododendron sp. 



No. 7171. A low-growing shrub with 

 ascending branches forming sprawling tangles 

 in rather swampy ground in well-shaded 

 thickets, at altitudes between 8,000 and 9,000 

 feet. 



72557. Rhododendron sp. 



No. 7184. A small compact bushy shrub, 

 sometimes 4 or 5 feet high, but more often 

 less than 2 feet, scattered on the sunniest slope 

 of steep granite screes, at an altitude of 11,000 

 feet. The quite tiny plants have been a mass 

 of flowers which were borne very freely in 

 trusses of four to seven. This species is 

 quite distinct from No. 7123 [No. 72548], but 

 may be seen growing within a few feet of it, 

 the latter in the shelter of the Abies and 

 Larix forests, the former in the open. 



72558. Rhododendron sp. 



No. 7188. A small compact bushy under- 

 shrub 1 to 2 feet high in open places, but taller 

 and lankier in the Abies forest, found at alti- 

 tudes between 10,000 and 11,000 feet. The 

 flowers are plum purple or inclining to crim- 

 son on the one hand and to violet on the other. 



72559. Rhododendron sp. 



No. 7189. A bush 4 to 6 feet high, forming 

 dense thickets on steep rocky slopes, at alti- 

 tudes between 10,000 and 11,000 feet. In the 

 Abies forest it forms much of the underbrush, 

 growing very rank. 



72560. Rhododendron sp. 



No. 7190. A shrub 5 feet high, growing at 

 altitudes between 10,000 and 11,000 feet. It 

 was growing on a steep bowlder scree among 

 thickets of Nos. 7184, 7189, and 7108 [Nos. 

 72557, 72559, and 72545]. It has the fruits of 

 No. 7184 [No. 72557], but the foliage is more

 hybrid.

 inches wide, hang down and the truss is 

 many-flowered. 



72563. Rhododendron sp. 



No. 7455. A bushy shrub, growing on an

72565. Rhododendron sp. 



No. 7642. Dichu Valley. A small or 

 medium-sized tree between 30 and 40 feet 

 high, growing at an altitude of 8,000 feet. The 

 young foliage is very long and narrow, and 

 when matured it is dull dark green above, 

 with conspicuous yellow midrib and primary 

 veins, and the under surface is silver bronze. 

 The fruits, about 16 in number, are in a long
