W e have alluded to this Rubus in defcribing the fruticofus,
t. 715. Although equally common with that, it has been
altogether neglected, or at mod allowed to be a variety, till
Mr. Crowe examined, and, in our opinion, fully afcertained it
as a fpecies. Dillenius, in Ray’s Synopfis p. 4^7* teems to
hint at it as differing from the common bramble in having
(e earlier, larger, and white blof fomswhi ch is true. Its
more effential differences however confift in the flem being
roundifh, biennial, not truly fhrubby and perennial; much
more brittle; fo that it is reje&ed by thatchers, who ufe
the other for binding their thatch; all the prickles nearly
ftraight, not hooked ; the leaflets large, always green on both
lides, never white beneath, fometimes very exactly refembling
the leaves of a hazel; the lateral ones feffile. Add to this
that the fruit is earlier, of a browner black, more gratefully acid
than in the fruticofus, and compofed of rather fewer grains. The
calyx of the fruit is reflexed; for an obfervation to the contrary
in the Flo. Britannica, borrowed from Mr. Wigg, rather belongs
to R. cafus, as we have this fummer verified.
Prof. Hoffmann thinks this bramble is the fruticofus of his
German Flora for 1800, and the true fruticofus his tomentofus ;
but a fpecimen communicated by Dr. Schrader proves the
latter to be quite different from both ours.
