B y no means an uncommon kind of Jungermannia, especially
in moist places, among Bog-moss and Mar chan tics.
The stems are short, creeping, mostly simple, leafy, rather
thick, and swelling upward. Leaves spreading, in two ranks,
the upper ones most crowded, all light green, with a singularly
crisped and jagged aspect; partly clasping the stem with their
broad base; their figure very irregular but in some measure
square, cut into two or three very unequal and various segments,
some of which are acutely notched. Sheath solitary, terminal, obovate,
the mouth contracted and finely laciniated.
This is allied to excisa, t. 2497, but abundantly distinct.
