sometimes divided by a delicate wall into two cells. In exposed localities the 
stems, leaves and gemmae acquire a characteristic brownish yellow colora- 
tion. 
The presence of underleaves will at once distinguish L. Kunzeanairova 
such species as Sphenolobus Michauxii, Marsupella emarginata and 
Lophozia uiflata , ail of which it somewhat resembles in general appearance. 
Among New England species its closest relative is undoubtedly L. Fioerkii , 
which has trifid or quadrifid leaves with a little group of marginal cilia close 
to the postical base. There is usually no indication whatever of basal cilia 
in L. Kunzeana , although sometimes one or two minute and indistinct teeth 
may be found in this position. 1 * Its relationship to L. Fioerkii and to 
other members of the barbatae-gvonp is clearly shown by the occasional pres- 
ence of a third lobe and by the constant occurrence of underleaves, and it 
would seem as if these characters were sufficient to exclude it from the genus 
Sphenolobus, where it is placed by Stephani.” Evans, Rhodora, 7: 52. 1905.

Already reported from Miquelon Island, from a few stations in Canada and 
from Colorado, but apparently new to the eastern United States* Lophozia 
Muelleri is a member of a group of closely related species which have long 
been a puzzle to European hepaticologists. The group has recently been 
studied by Schiffner, 3 who ascribes to it the following characters: leaves 
always bind: underleaves more or less developed even on slender stems: 
perichaetial bracts usually but little differentiated from the leaves: perianth 
(Cylindrical or barrel-shaped, terete (or slightly plicate in the upper part), con- 
tracted into a tubular beak; perigonal bracts with a third dorsal tooth. 
[Schiffner recognizes seven species, five of which have been recorded from 
North America. L. Muelleri is distinguished from its allies by its relatively 
small size, by its more or less acute leaf-lobes, by its rather thin-walled 
feaf-cells with small but distinct trigones and a minutely verruculose or 
striate cuticle, by its dioicous inflorescence and by its lack of gemmae. Its 
nearest relative is doubtless L . heterocolpa (Thed.') M, A. Howe, which is 
known in North America from Greenland, from the shores of Lake Superior,
