Other rarities include Polygala subspinosa Watson (No. 32), 

 BricMlia Unifolla D. C. Eaton (No. 89) and Eriogonum villifio- 

 rum Gray (No. 243). On one of the exposed rocky slopes was 

 gathered a dwarfed variety of Cercocarpus ledifolius Nutt., or pos- 

 sibly a new species to which the name of Cercocarpus intricatus n. 

 sp. (No. 59) may be provisionally applied. Along the gravelly 

 margins of Cedar Creek was found Astragalus Sonorm Gray (No. 

 53), Astragalus -longocarpus Gray (No. 52) Thelesperma sub- 

 nudum Gray, n. sp. (No. 109) and Lygodesmia grandifiora Gray 

 (No. 128). On shaded hill-sides, Cercocarpus ledifolius Nutt., 

 Cowania Mexicana Don.. and Fraxinus anomala Torr. (No. 210), 

 are abundant. Having soon exhausted this scanty flora, my at- 

 tention was directed to the high mountain range of the Wahsatch, 

 rising abruptly to the East, and overlooking the southern exten- 

 sion of the great interior basin. An ascent of about 3,000 feet 

 in a distance of three miles, brings us to the outer crest of the 

 range, which extends eastward in an irregular series of undula- 

 tions to the upper Sevier valley. At several points on the lee 

 side of steep ridges there were still the remains of rapidly wasting 

 snow banks. Notwithstanding the comparative elevation and 

 freshness of vegetation, there was a scant supply of surface water 

 except immediately adjoining large snow banks. The prevalent 

 timber growth was made up of interrupted groves of Aspen pop- 

 lar, some high ridges in the distance showing a few scattered pines 

 and spruces. Four miles back towards the interior of the range, 

 the country expands into wide grassy slopes, and frequent springs 

 and running streams bordered by snow drifts, give unwonted fresh- 

 ness to the pastoral scenery. Here is located the summer sheep 

 range, and dairy farms of this district, of which the only apparent 

 drawback to their attractive and productive features, is the an- 

 noying prevalence of blood-thirsty flies. 



The botanical features are very similar to other elevated pas- 

 toral distriets in the interior West. Senecios and Arnicas serve 

 to give a yellow cast to the open grassy meadows ; shades of blue 

 are supplied by thrifty Delphiniums. In the aspen copses there 

 is a dense undergrowth made up mainly of Prunus, Rosa, Sym- 

 phoricarpus, and Salix. Less conspicuous but more interesting as 

 poeuliar to the flora of this district may be noted Cahui'lrimt 

 pygmcea Gray, Trifolium eriocephalum Gray (No. 35), Oxgtrophi* 

 campestris var. ? and Cordylanthus Kingii Watson (No. 156).
