Frullaniae were noted, probably because the scrub was not large enough to af- 
ford a foothold, and rotten-log species were rare, as in most European reports. 
While it is perhaps hardly valuable, it may be interesting to compare the 
N. E. and Maine lists with some of the local north-European floras. Of the 216 
species given in Kaalaas ’ Norwegian list, 111 are common to N. E., 89 to Maine, 
91 to N. H. In Lindberg & Arnell’s Siberian list, 96 species in all, 72 are com- 
mon to N. E., 58 to Maine, 62 to N. H. In Bernet, Hepatiques’ de la Sud-ouest 
de la Suisse, 142 species in all, 87 are common to N. E., 70 to Maine, 78 to N. 
H. In Macvicar, Handbook of British Hepatics, 274 species in all, 128 are com- 
mon to N. E., 102 to Maine, 104 to N. H. 
It is fairer to compare the Sarekgebirge and Siberian lists with Maine, as 
they are records of single trips, while the other lists are those of carefully-ex- 
plored countries. A beginning only has been made in Maine. It will be ob- 
served that in each case, more species are credited to N. H. than to Maine. This 
is no reflection upon the wealth of the Maine flora, but rather to her credit, that 
with so little systematic collecting, the list so nearly approaches that of N. H., 
which has been visited and revisited by every collector for decades, especially 
the Presidential Range. 
The notes given above show the highly boreal character of the Round Moun- 
tain Lake region, and give hope for many further species which may await en- 
rollment upon the N. E. list.

AN INTERESTING MOSS 
H. S. Jewett, M.D. 
On Dec. 4, 1913, in the water, and upon the limestone walls of a spring, 
and its overflow brook, in Neff Park, Yellow Springs, Greene Co., Ohio, I found 
a number of mats of moss. The entire southwest section of Ohio has been 
denuded to the lower beds of the Upper Silurian epoch, hence the whole region 
rests on limestone, and all our water, whether river, creek, brook, or spring ,is 
strongly calcareous, and the forests are all deciduous. 
Some of the moss mats were so far above the water in the spring that their 
water supply was derived entirely from rain and dew; these were all Ambly- 
stegium filicinum (L.) De Not. Seven or eight of the mats were growing on the 
stones at the waterline, extending four to ten inches upwards and three or more 
inches downwards into the water, and it is in these partly submerged mats that 
the interest centers. As all these mats proved to be alike in moss contents 
and arrangement, I shall divide them into three zones to make their description 
easy. 
Zone 1 comprises all of the mats below the waterline; i. e. constantly sub- 
merged, including a few tufts growing on the bottom of the spring and having, 
apparently, no connection with the mats on the sides of the spring.
