little balls at the extremity of leafless prolongations of the stem.
Hence Linnceus referred the plant to his Mnium.
b. Leaves bi-tri-jid or-partite, the segments equal.
* Stipules much smaller than and very distinct from the leaves.

Moist and shady situations, on hedge-banks, particularly among moss
and the roots of trees. /3. In very wet parts of Holt Heath, Norfolk,
Rev. R. B. Francis. Fr. Winter and Spr.—This Jungermannia (as well
as some others) has a peculiarly agreeable scent, which may perhaps
best be compared to that of the dry earth suddenly moistened by a
shower. Colour a pale and whitish green.
49. J. heterophjlla, Schrad. (various- leaved Jungermannia);
stem creeping branched, leaves roundish ovate decurrent the
extremity rarely acutely generally obtusely emarginate or entire,
stipules bi-quadrifid here and there Iaciniated, fruit termi-

Mr. Don. Mr. Wilson finds it near Turk Cascade, Killarney (but rare,)
