COMMUNICATED by Mr. Turner, who received Irish specimens
from Miss Hutchins. Mr. G. Don has found the same
species in Scotland.
It grows on shady rocks, in dense patches, resembling those of
J. incisa, t. 2528, of a pale yellowish green, with a brownish tint.
Each plant creeps on the ground, attached by numerous radicles,
being usually quite simple, scarcely half an inch long. Some of
our specimens however show a young shoot, such as Mr. Hooker
has now and then observed. The leaves clothe the upper side of
the stem, in two ranks, being roundish or ovate, more or less upright,
entire except a terminal notch, making an acute angle, between
two'equal acute points. Beneath is a simple row of projecting
stipulaceous scales, each nearly half the length of a leaf, ovate,
acute, with a tooth at each side. The sheaths are lateral, solitary,
obovate, much drawn in at the orifice, with three or four
three-pointed leaves at the base.
