Found on the Continent and in North America.
O b s ,—Eecognised at once, by the remarkably large marginal
cells, from any of the other round-leaved Jungermania.
The perianths are generalfy 4-angled, sometimes more ; Dr.
Spruce met with a form in the Pyrenees with 8, some with 7, 6,
and 5, but he could find no difference whatever from tlie ordinary
J. crenulata, and remarks: “ So that an occasional duplication of
one or more of the perianth-angles would seem a common occurrence
in this section.”

Dioicous, cæspitose, tufts shallow, innovations plentiful,
marginal cells similar to the others, on stronger stems the
tendency to become larger is observable, bracts similar to the
upper leaves, perianth muoronate, margin of mouth slightly
crenulate, angles of perianth cristulate, calyptra delicate, claret
coloured.
Fruits April, May.

it simqily as a variety.
