two eastern grasses, Oryzopsis juncea and O. asperifolia. Near the 
railroad occurred two forms of Poa nevadensis, and Bromus pumpillia- 
nus, both of a more western range. On a wooded hill, together with 
the three common Stipas, S. spartea, S. comata, and 8. viridula, grew a 
fourth, 8S. richardsonii, of a more western range, and also Danthonia 
spicata, from the East. 
But the most peculiar feature of this region is the damp atmosphere. 
The Harney Range differs in that respect from the Northern Hills. On 
account of this dampness, and differently from mountain regions in 
general, the Harney Range abounds in lichens, liverworts, mosses, and 
ferns, especially on the north side of the crags, where the rocks in many 
places are literally covered by lichens and the base and crevices lined 
by mosses and ferns. The lichens and mosses were collected only inci- 
dentally, but a good collection of ferns was made. My list contains the 
following from this region: 
Polypodium vulgare. Pteris aquilina, 
Asplenium trichomanes. Asplenium septentrionale. 
Asplenium filix-fumina, Dryopteris filix-mas. 
Phegopteris dryopteris. Cystopteris fragilis, 
Woodsia oregana. Woodsia scopulina., 
Botrychium matricariofolium? Selaginella rupestris. 
Polypodium vulgare rotundatum., 
LIMESTONE DISTRICT. 
The Limestone District is a high table-land, running from south to 
north, on the Wyoming line. It is separated from the Harney Range 
and the other hills by a valley. This table-land is the watershed of the 
Black Hills, giving rise to Spearfish, Rapid, French, and Red Canyon 
creeks on the east side, and Red Water, Inyankara, and Beaver creeks. 
on the west side. The plateau is 1,800 to 2,000 meters high, the highest 
point, Crooks Tower, being, next to Harney Peak, the highest in the 
hills. The surface is made up of pine-covered ridges running north and 
south. The valleys between these ridges are composed of excellent 
hay land. The region resembles much some parts of Sweden. The 
pine-covered hills were here, so also the meadows with the knee-deep 
grass, and the flowers were in greater profusion and greater variety of 
color than I have seen elsewhere in America. The Swedish species 
were seldom present, but they had their counterparts: Hieracium, 
Scorzonera, and Hypocheris were matched by Rudbeckia hirta, Gaillardia 
aristata, and Helianthus maxvimiliani; Lathyrus and Vieta by Lupinus 
parviflorus and LL, sericeus; Geranium sylvaticum by Geranium richard- 
soniit; Chrysanthemum leucanthemum by Aster ptarmicoides; and Sol- 
idago virgaurea by Solidago missouriensis, In the border of the woods 
the same old Epilobium angustifolium presented itself, 
The only trees seen in the district were the pine and the quaking 
aspen.
