By most American authors this species has been referred to J. excisa 
Dicks., and it is described under this name in the sixth edition of the Manual. 
It is probable that the true J. excisa was a composite species including among 
others the J. bicrenata of Schmidel, but there is so much uncertainty about 
it that some European writers have given up the name altogether while 
others reserve it for J. capitata Hook. {==/. intermedia Lindenb.), a very 
different species from Lophozia bicrenata. J. capitata is described in the 
Manual as J. excisa , var. crispa Hook, and has not yet been definitely 
reported from New England. L. bicrenata on the contrary is not uncom- 
mon and is usually found growing on the earth in woods or along their bor- 
ders. It has been collected from near the coast to an altitude of 5000 ft. in 
the White Mountains and does not vary markedly in different localities. To 
the description given in the Manual it may be added that the inflorescence is 
paroicous and that the plants, which are usually more or less tinged with red- 
dish, commonly give off a peculiar aromatic odor. New England specimens 
from the following stations are in the writer’s herbarium: Crawford Bridal 
Path and Jackson, New Hampshire (A. TV. E .): Andover, Vermont ( IV. G. 
Fartow): Woods Holl, Massachusetts ( A . IV. E .): Orange and Hamden, 
Connecticut (A. IV. E.). Plate IX. Figs. 5—9.

In a note on I^ophozia bicrenata * the writer made the statement that the 
true L. excisa , with which L. bicrenataha.s been confused in North America, 
had not been definitely reported from New England. The specimens 
recorded above, however, were already collected but through an error had 
been referred to another species. L. excisa agrees with L. bicrenata in its 
paroicous inflorescence. It is distinguished by its larger size and more deli- 
cate texture, the leaf-cell being thin-walled, except for the small trigones at 
the angles, instead of being uniformly thick-walled throughout. It also 
lacks the brownish or reddish pigmentation and the peculiar aromatic odor 
which are usually associated with L. bicrenata. In general appearance it 
bears considerable resemblance to small forms of L. ventricosa. Its paroi- 
cous inflorescence will at once separate it from this species, and it is usually 
easy to recognize the perigonial bracts, even after the antheridia have dis- 
appeared, by the small pocket or indexed tooth at the antical base. In spite 
of the uncertainty connected with the original J. excisa of Dickson, most 
recent writers associate this name with the present plant. Plate IX. Figs.
