Other plants, whose occurrence and distribution deserve more 
than passing notice, are as follows : 
Arenaria Groenlandica, Spreng. Acres and acres of the upper 
slopes of the mountain are covered with this delicate plant. It grows 
also on Mt. Bigelow, in far less profusion. 
Trifolium hybridum, L., grows above timber-line with Phleum pra- 
tense, L. It is rather remarkable that they should have been intro- 
. duced at such an elevation, higher than any horse could climb. 
Rubus Chamaemorus, L., grows in the sphagnum on the higher 
part of the saddle toward the horn. This has been reported from 
the higher White Mountains, from Baldpate Mountain, Grafton, 
Maine, and it reappears as an arctic coast plant in eastern Maine. 
It has not been found on Katahdin. 
Potentilla tridentata, Ait., hardly deserves mention as a mountain 
plant, for it is frequent on rocky slopes and dry sand-plains at all alti- 
tudes throughout the region, down as low as 350 feet in Jay, the south- 
ern town of the county, and throughout the Androscoggin valley to the 
coast. 
Solidago macrophylla, Pursh, is abundant in the wooded parts of the 
mountain, and is frequent in mountain woods above 1800 feet 
throughout the county. 
Vaccinium Pennsylvanicum, Lam., var. angustifolium, Gray. This 
grows abundantly on exposed slopes, often with the type. I have 
also collected it on the Abraham range, about ten miles away (RHo- 
DORA, i. 191). 
Vaccinium uliginosum, L., is abundant above timber-line here and 
throughout the region. It also occurs along the Carrabassett in 
Jerusalem, and as low as 700 feet at Farmington (RHODORA i. 162). 
Vaccinium caespitosum, Michx., was collected by M. L. Fernald and 
the author in 1894, growing in moss near the pinnacle. This I did not
