BOTANICAL OBSERVATIONS IN WESTERN WYOMING. 7 
valleys. After passing the first series of steep ridges, which gen- 
erally present an abrupt escarpment towards the main axis of the 
range, the interior valleys are spread out in the form of irregular 
basins, bordered by deep pine woods. Within these timbered 
recesses we occasionally encounter small grassy. parks, or alpine 
bogs occupied by a close, clumpy growth of willows. Through 
these, course clear mountain streams generally hidden from view 
by overhanging vegetation. During the season of melting snow 
in the early summer months, these meadows frequently conceal 
‘treacherous bogs greatly impeding travel, while small ponds and 
occasional permanent lakes are notinfrequent. In this variety of 
surface exposure, limited in every direction by irregular, rocky 
ridges, variously set off with extensive snow drifts, we have all 
the conditions of a most attractive mountain fore. 
We accordingly find here in somewhat confused association the 
following plants:—Draba Alpina L., Lup: dcespitosus Nutt., 
pestris L., Oxytropis viscida Nutt.? (or a spe es near it), Sedum 
agai Ph., Sedum rhodanthum Gray, Actinella grandiflora 
, Antennaria dioica L., Senecio lugens Rich., Ialmia 
labios i Synthyris plantaginea Benth., Mertensiu paniculata 
’ Dougl., Gilia nudicaulis Gray, Androsace septentr ionalis L., Prim- 
ula Parryi Gray, Gentiana humilis Stev., Phacelia sericea Gray. 
In succeeding articles the flora of the Owl Creek range and of 
the high mountain district between the Big-Horn and Yellowstone 
* basins will be noticed.
