this heath, which is also being encroached upon from below by the 
forest. ‘That this heath is one day doomed to be a feature of the 
past can hardly be doubted. 
At the base of the South wall of our basin, over which the cataract 
inlet of Davis Pond falls, is a meadow-like society similar to that 
found at the base of the dripping West wall of the North Basin. 
Indeed, its very presence is due to the spray and seepage from the 
cliffs above. Calamagrostis Canadensis, C. Langsdorfü, Scirpus 
caespitosus, Prenanthes trifoliolata, Aster radula, Habenaria dilatata, 
Solidago macrophylla, Arnica Chamissonis, and Diervilla trifida are 
among the more characteristic forms which constitute this meadow 
society. 
ADDITIONS TO THE VASCULAR FLORA OF Mount KTAADN. 
In presenting these additions and extensions in range of the flora 
of Mount Ktaadn it must be stated that our report embraces much 
territory previously unexplored, the North West Basin, the west 
slopes of the South Mountain, the North Spur, and the outer limits 
of the Great Basin including a small sphagnum bog along the trail 
near the foot of Lower Basin Pond. Many of our rarest finds, how- 
ever, were made in those places most thoroughly explored by former 
parties, which illustrates the very restricted distribution of the rarer 
forms and strongly emphasizes “that many seasons will be required 
before we know approximately the bulk of its flora.” 
We were disappointed in not finding the rare little Saxifraga 
stellaris comosa, which has here its only stations in the eastern United 
States, and the evasive Carex rariffora not reported since Prof. 
Goodale found it in 1861. Several species of carices and grasses 
also escaped our notice. "Though we found not all the old we were 
richly rewarded by the new. Fernald’s summary! of the Ktaadn 
flora enumerates one hundred and eighty-three species and varieties. 
To this we have added thirty-eight forms, making the total known 
vascular flora of Mount Ktaadn two hundred and twenty-one species 
and varieties. 
In the appended list the species new to Ktaadn are indicated by an
