Oxalis Acetosella ; and Trientalis Americana and Maianthemum Can- 
adense were frequent. Every open space was filled by Aspidium 
spinulosum. ‘This was the only abundant fern, though on the lower 
slopes it was accompanied by Phegopteris polypodioides and Asplenium 
Filix-foemina. Strangely enough, however, there was an isolated patch 
of these two on the bare part of the middle range, far above any other 
ferns. Chiogenes serpyllifolia, Solidago macrophylla, Linnaea borealis 
and Goodyera repens grew in the upper regions. The only Carices in 
the mountain woods were Carex intumescens, C. rosea, C. laxiflora and 
C. canescens, var. alpicola, and these were not abundant. No grasses 
were found. 
The first range of the mountain is so heavily wooded that it bore 
nothing strictly alpine. An open place near its highest peak was cov- 
ered with Rumex Acetosella, which grew with all the assurance of a 
native. The second range was also disappointing. It is very rocky, 
and the principal plants were Poa nemoralis, Anaphalis margaritacea, 
Kalmia angustifolia, Vaccinium Vitis-Idaea, V. uliginosum, V. Penn- 
sylvanicum, Ledum latifolium and Empetrum nigrum. Narrow-leaved 
alpine forms of the last three plants were as common as the typical 
forms. Lycopodium annotinum, var. pungens, was also present, shading 
imperceptibly into the type. Cornus Canadensis was in blossom 
everywhere. 
Bald Mountain is the highest part of the range, and furnished the 
most interesting field. Here, for the first time on the range, occurred 
a few patches of sphagnum peat, and in this grew Comandra livida, 
Vaccinium Oxycoccus and Kalmia glauca. Higher up on the exposed 
parts, near the summit, grew Juncus trifidus, Diapensia Lapponica, 
Selaginella rupestris, and, at the very summit of Bald Mountain, at the 
highest point of the range, grew a large mass of Carex rigida, Gooden., 
var. Bigelovit, Tuckerm. (C. vulgaris, Fries, var. hyperborea, Boott.). 
A comparison with the flora of Mt. Saddleback, about ten miles 
away, reveals certain differences. Arenaria Groenlandica, Vaccinium 
caespitosum and Calamagrostis Langsdorfit, which grow near the * pin- 
nacle ' of Saddleback, do not occur on Abraham. This lack, it seems 
to me, must be ascribed to the aridity of the range, rather than to any 
great difference in altitude. Saddleback abounds in springs, and has a 
rainwater pond on top, and great masses of sphagnum are frequent, 
while the entire Abraham range is dry, and has only a very few patches 
of sphagnum.
