On trunks, parasitic on other hepatics.
Forming minute scattered, or dense tufts. About
f inch high, light green, usually cæspitose, but
when growing amongst other species decumbent ;
shoots minute, naked at the base. Leaves
distant, alternate, erect, then spreading, from
a narrow base, wedge-shaped or obovate, bidentate
at the apex, with an acute shallow sinus, lobes acute,
divergent. Amphigastria generally present, minute,
subulate, toothed on one side, or acutely bidentate.
Taylor says it is closely allied to P . bidenticulata.
from which it may be recognised by its smaller size,
the shallower division of the leaves, their less acuminated
segments, by their being shorter, by their
far smaller cells, by the weak connexion of the
leaves to the stems, by the paler colour of the adult
plants, more spreading leaves, and by the roots
occupying a greater length of stem.— {Plate 4,
