mon, not only on the summits, but on the rocks along the brooks, and 
usually heavily fruited, particularly on the north sides of the rocks. 
One of the most interesting features of the bryophytic flora is the occur- 
rence of Dicr anodontium longirostre B. & S. exemplifying, as it does, the 
writer’s theory as to its habitat,— namely, that it grows near water not above 
45 degrees temperature. Of three stations, the largest is at Tyler’s Spring 
(45 deg.) where it grows very abundantly on the banks near by, which are 
full- of rotten wood. The second station is in a similar place by a spring (40 
deg.) between the two Greeley Ponds: the third station is on a rock, near a 
cold stream feeding the upper Greeley Pond. Dicranodontium is instantly 
known by its intense green color, and its moulting when touched. “ Folia — 
quam maxime fragilia.” (Bry. Eur. ) The writer has so far always found 
it sterile in New England : it prefers banks full of old wood, but is sometimes 
found upon rocks. 
On account of the exclusively siliceous formations, the Tortulaceae- 
Saelania, Fissidens, etc. are lacking. Bryum is mostly absent, the lack of 
B. proliferum (L.) Sibth., being rather noticeable, but Pohlia nutans 
(Schreb,) Lindb., and P. elongata Hedw. are frequent. 
Mnia are abundant, but of few species. Trematodon ambiguus (Hedw.) 
Hornsch. is frequent, in dry fields, or by sandy roadsides. The Poly- 
trichaceae are well represented, with five species of Polytrichum, three of 
Pogonatum, and one Catharinea. 
The sphagnum bogs are almost pure stands, without the Camptothe- 
cium,the various Hypna, scorpioides L., stellatum Schreb., revolvers Swz. 
Thuidium B landowii (W . & M.) B. & S. etc. of calcareous bogs. Homalia 
/ amesii Sch. is quite common on the north and northwest sides of granite 
boulders, also P lagiothecium Muellerianum Sch. in similar but more ele- 
vated situations. 
Of the Marchantiaceae, only Marchantia and Conocephalum appear. 
Diplophylleia taxifolia (Wahl.) Trevis. is rather common along the bases of 
rocks in stations above the level of the valley itself. Lophozia gracilis 
(Schleich.) Steph. is ubiquitous, and L. incisa (Schrad. ) Dum. is somewhat 
frequent on old stumps, L. barbata (Schreb.) Dum. is apparently absent. 
The numerous trout streams have an abundant, but not particularly 
varied flora, Scapania, Fontinalis, Rhacomitrium aciculare Brid., Hypnum 
eugyrium B. & S., H. dilatatum Wils. with Marsupellae in the upper 
reaches. 
In general, the list makes a good showing for a non-calcareous region, 
although it cannot compare with one in which both calcareous and siliceous 
formations are found. 
These are merely notes of a several-week’s stay, to be regarded as pre- 
liminary only, and not as exhausting the possibilities of a region which will 
well repay further exploration.
