'uiwermannia. HEPATIC7K. 113
Very nearly allied to ./. excisa; but the foliage has a much more loosely
cellular texture (which also keeps it distinct from -/. iucisa) and the
upper leaves, which, too, are tri-quadrifid, are collected into a head at
the extremity of the stem or branch.
27. J. incisa, Schrad. (^jag-leaved Jungermannia); stem pros-

Moist shady banks, especially on clay. Fr. Aut. and Spr.—This
species is quite peculiar. Its short and stout stems are furnished with
long purple radicles for the whole length of their underside. Leaves large
in proportion to the size of the plant and closely set, spreading. Anthers,
as they are called, are found naked upon the stems. The perianth is
singularly large, campanulate, often cut, with 4—5 external Bubulate
appendages or bracteas. The cajmde is globose, of a very thin and fragile
texture, bursting irregularly and containing teed* which are densely muri-
cated. Sometimes 2 or 3 capsules arise from the same calyx.
*** Leaves bifid, the segments unequal, conduplicate,
