region of the Atlantic Seaboard States. At any rate it presents a 
very happy illustration of the theory which Prof. Fernald has so 
ably demonstrated. 
Sphagnum Pylaesiti Brid. Abundant in a shallow pond near 
Armdale, just outside of Halifax. 
Andrea petrophila Ehrh. In dense reddish cushions on the granite 
ledges near Uniacke Lake, Hants Co. 
Andrea crassinervia Bruch. With the preceding and more abundant. 
Also on dry sandstone faces bordering Shubenacadie Grand Lake, Hali- 
fax Co. Fruiting freely. 
Dicranum fulvum Hook. Frequent on boulder faces throughout 
the range. 
Dicranum fuscescens Turn. Rather common in thin soil on boulders 
and ledges. 
Dicranum longifolium Ehrh. Rock faces near Armdale. 
Dicranum montanum Hedw. Rock faces in woods near Armdale. 
Dicranum spurium Hedw. Thin soil on sandstone and granite 
ledges in Hants Co. and Halifax.Co. Frequent and variable. 
Dicranum viride Schimp. On the bark of living trees bordering

Grimmia maritima Turn. Very abundant in dense black cushions 
on the shore rocks and headlands of Cape Forchu, Yarmouth Co. 
Grimmia Olneyi Sulliv. On sandstone rocks, Blueberry Point, 
Shubenacadie Grand Lake. This species has been found from the 
New England States west to southern Ontario and southward but 
the present record seems to extend the range quite a distance in the 
northeasterly direction. The tufts were vigorous and mostly pure 
with about the average number of fertile plants but in spots a mixture 
of Andrea crassinervia and Rhacomitrium microcarpum was much in 
evidence. 
Rhacomitrium aciculare (L.) Brid. Frequent on wet rocks along 
the lakes shores. Generally sterile but occasional colonies richly 
set with fruit. 
Rhacomitrium heterostichum alopecurum Hübn. Abundant on 
granite ledges near Lake Uniacke. 
Rhacomitrium heterostichum gracilescens B. & S. With the preceding 
and hardly separable from it except by the strictly muticous leaves.
