which is provided with small, separate teeth, most two cells long. Capsule 
and spores are chestnut-brown. 
The male plant is slender, and the usually terminal androeceum forms a 
cone-like spike, with about fifteen pairs of closely imbricated bracts, mostly 
containing two antheridia. 
Gemmae present in great abundance, at the apex of the shoots pale 
green, on the older leaves sometimes reddish. They are small, obtusely 
tri- or quadrangular, seldom divided, the leaf-tips are often eaten away by 
them. 
The species avoids limestone. Careful search of the mountains about 
Waterville, N. H., has been hitherto unavailing. It certainly shuns the 
crumbly trachytic granite of Mt. Osceola, at least. The most likely place 
for it is Mt. Lafayette, as that most resembles Mt. Mansfield, and any bryo- 
logist visiting that range is earnestly requested to watch for it, after passing 
Eagle-Lake, from the timber-line up. 
Schiffner. in his notes on L. longifloi^a in his Hep. Eur. Exsiccatae, 
gives his reasons for recognizing these “ kleine Arten. ” “It is impossible 
to tell which is the Stammform within the whole group, beneath which the 
others are to be arranged as varieties or subspecies — quite possibly none 
of the described or now living forms. One could imagine, that through 
making “ little species,” that naturally only are distinguished by the 
specialist with certainty, the study of the hepaticae will be made too dif- 
ficult for the beginner. Aside from the fact, that Science needs not to 
take such things into consideration, it is for the beginner to consider, that 
one must use more trouble and time for the working into a complicated 
and difficult matter than in the easier field, and such as have not com- 
mand over an iron diligence and a limitless patience, had better remain far 
away from the study of Hepaticology.” 
However, for anyone who is determined to have acquaintance with 
these plants, they will amply repay all effort expended upon them, for 
Warnstorf declares their study to be “die reinste Freude, die man haben
