ii6 Muhlenbergia, Volume 7 



From 7300 feet to the head of the ridge there is an abund- 

 ant growth of grasses and other herbaceous plants of various 

 sorts, as is well shown in the illustration. The soil is loose and 

 well adapted to catch and readily absorb the moisture. Had 

 sheep been allowed on this part of the range, the conditions 

 w^ould be ver}' different. There would be many bare spots with 

 hard soil, from which the water would readily run off. 



In open places at 9000 feet where vegetation is rather scat- 

 tered were found several species of Eriogonum, among them E. 

 Kingii^ some of the original specimens of which came from the 

 Clover mountains. This is one of the low, tufted species, the 

 erect stems not over two or three inches long, topped by small 

 heads of w^hiteor crean:y flowers. Some of its companions were 

 Stenotus acanlis, Homalobus tenelhis^ Arenaria aciileata, A. iiin- 

 tahensis^ and Astragalus calycosiis. 



One of the most interesting places was the steep noith slope 

 of the basin beneath the snowbanks which circled the inner 

 edge of the rim. Here was a wonderful display of bright yel- 

 low Potentilla diversifolia^ Dasiophora fniticosa, and Rajiiiticii- 

 lus Eschscholtzii^ mingling with the red of RJwdiola integrifolia 

 and a very beautiful little Dodecatheon, as yet undetermined. 



About the rocks fringing the south rim of the basin was a 

 beautiful assemblage of Erigeron, mixed with Mertensia lan- 

 ceolata and Ribes inebrnans. 



From this point up to the saddle in the crest of the central 

 ridge at 10500 feet, the somewhat drier and stonier slope was 

 covered with a stunted sage brush, cluinps of Eriog. )nnm, Gilia 

 montana^ Dactylophyllum, and Keiitropliyta tegeiaria. 



Aconogo)unn alpinitm Schur. Watson lists this under 

 PoIygoJium poIymorphii))i var. alpinum as from the "East Hum- 

 boldt Mountains," "on dry slopes." A few clumps of it were 

 found in moist places on the edge of the small lake in the basin. 



Aconiastylis sericea^ Greene, was first found at 8750 feet on 

 a damp north slope where snow had recenth- melted, and is 

 from the type local it\'. The following charact(.^is are not men- 

 tioned in the original description in Pittonia \\\ 172, as Geutn
