an inch and a half in diameter, flattish, somewhat orbicular, between
coriaceous and gelatinous, when dry almost horny, of a deep but dull
purple colour, much lobed and curled, like some Gyrophoree, filled with
crowded clusters of granules, which, if minutely examined, are found
to be mostly arranged in fours. Hook.

In fresh-water streams, &c, Pentland hills, Dr. Greville. Appin, in
stagnant water, Capt. Carmichael.— " The gelatinous mass, scarcely deserving
the name of frond, is quite shapeless. Its colour is owing to the
granules, which are mostly solitary, but sometimes approximated in pairs
or fours." Carm. MSS.
6. P. rupestris, Lyngb. (yellowish Bock Palmella); frond
shapeless rugose yellowish-olive, granules globose associated in
fours (sometimes scattered). Lyngb. Hydroph. Dan. t. 69.

On moist, overhanging cliffs. Appin, Captain Carmichael.— " It occurs
as a dirty-yellowish gelatinous crust, often hanging down in flakes
from the face of the rock. The granules, in my specimens, are mostly
solitary, with a dot in the centre ; but every thing connected with these
imperfect, not to say doubtful, vegetables, is liable to the widest variations."
