murely hiding their nodding heads in the shade are Helianthella 3 
quinquenervis arizonica and the elegant Senecio Rusbyi, all of 
the great composite family. Of smaller build and nestling more 
snugly near the cool earth, are plants whose bloom is white and 
of other humbler shades. ‘These are Cerastium texanum, Fra- 
garia bracteata, Ionoxalis Metcalfii, the twining Lathyrus gram- 
envifoltus, curious clusters of Thalesia fasciculata, and Viola can- 
adensis Rydbergit, which latter occasionally forsakes violet tra- 
dition and becomes bold to a height of fully twenty inches. Re- 
treating to the shadiest nooks, tall and graceful in its fern-like 
foliage, Pedicularis Gray? rarely rears its head. 
Upon the deep and fertile accumulations toward the foot of 
well protected slopes and in depressions, upon a background of 
Pteridium aquilinum pubescens, rise the blue and spire-like in- 
florescences of Delphinium scopulorum stachydeum; Oenothera 
flooker2, almost equally tall, displays acres of bright yellow, and 
on more trodden soil, O. mexicana leads a creeping existence. 
Occasionally the long, purplish heads of Agastache pallidifiora, 
a member of the mint family, come into view. J/rzs missourien-

ively, similar shades reappear in the graceful zcza americana, 
V. leucophaea, and the next of kin to our potato, Solanum tuber- 
osum boreale. Not too often vouchsafed to the eve, there ap- 
pears among silky seven-radiate leaves the deep red satin plush 
of Potentilla Thurber, of a hue and texture marvelously rich. 
As at rarer intervals the ground grows still more moist and 
springy, 77zfolium pinetorum often forms a dense carpet under.

and Hypericum formosum, and finally, clustering about the cool 
and living springs themselves, and only here, are found Zfz/c- 
bium neo-mexicanum, Ranunculus hydrocharotdes, the rare Lim- 
norchts sparsifiora, the equally rare Mimulus cardinals of gor- 
geous hue, the fern Athyrium cyclosorum, the great white um- 
bels of Lzgustecum Porteri, while Mimulus guttatus usually adds 
abundant gilding tothe scene. Fringing the foot of talus slopes
