GYROPHORA proboscidea,
Proboscis Gyrophora.
CRYPTOGAMIA Algce.
Gen. Char. Tubercles sessile, on a peltate frond, black,
with a plaited contorted disk, in whose clefts the
seeds are lodged.
Spec. Char. Frond membranous, notched; upper side
rugose, with elevated reticulations, of a smoky
ash-colour ; under smooth, naked and paler. Tubercles
top-shaped, prominent; their disk at
length rather convex, variously plaited.

N o t rare on the granite rocks of the Highlands, nor in the
north of England and Wales, generally accompanying our t. 522,
which is G. cylindrica of Acharius. We can however assure
those who are interested in the matter, that the real Lichen pro-
loscideus of Linnaeus, so fully described in Sp. PI. ed. 1. 1150,
is, beyond all doubt, a specimen of our t. 522, as nearly destitute
of fringe or hairs as the plant in our present plate. We assent
nevertheless to the cylindricus of Linnaeus, Sp. PI. ed. 1. 1144,
(to which Mon tin applied a most erroneous synonym of Dillenius,)
being also our t. 522. Linnaeus has justly noted in his own copy
of Sp. PI. that the Lichens in question are one and the same
species. The present indeed is more corrugated in its upper
surface, the other more furnished,with warty pustules, as well as
incomparably more fringed. The tubercles vary in degree of
elevation, and the names of proboscideus and cylindricus are
nearly equally unsuitable to the general form of both, though
well answering to the Linnaean specimen. We publish these
remarks, and the annexed plate, for the sake of illustration, as so
many botanists have separated these plants, which appear to us
varieties only, and for both which we would retain the name of
Gyrophora proboscidea. See Winch, v. 2. 43.
