EPPING FOREST RUBI.

And then, packing away the numerous specimens obtained during the
afternoon, the members of the party climbed into the drags, and a pleasant
drive of several miles by way of Braxted and Rivenhall, in the gathering dusk
of a beautiful summer evening, brought them to Witham station, and an
enjoyable excursion to a close.
Our thanks are due to Mr. E. E. Turner, not only for acting as
"Botanical Conductor," but also for revising the lists of plants, and for speci-
mens of several of them for the Club's Herbarium.
TWO MORE EPPING FOREST RUBI.
By J. T. POWELL.
Some years ago, when studying the Rubi of Epping Forest,
I collected two or three forms which I was unable to name. I
fortunately preserved the specimens, and recently submitted
them to the critical judgment of the Rev. W. Moyle Rogers,
F.L.S. One turns out to be a very interesting variety of R,
pallidus, W. & N., which, after being referred to R. lochri, Wirtg,
by Dr. Focke, the chief continental authority on the genus, has
been found to be identical with a Schleswig plant, for which
Friderichsen suggested the name leptopetalus, without describing
it. In Mr. Roger's Handbook of the British Rubi it is described as
a var, nov. under Friderichsen's name. Its full name is, there-
fore, R. pallidus W. &. N. (non Bab.) var. leptopetalus, Rogers.
My specimen was collected by the left of the Epping Road,
beyond Buckhurst Hill, in August, 1888. Another specimen,
which has stood over nearly as long, has been determined as
R. argentatus, P. J. Muell. This is decidedly a rare bramble
in the Forest, though fairly common in many parts of Britain.
I found it between the Roebuck and Warren Hill, and believe I
have seen it at High Beach.
The bramble recorded in the Essex Naturalist, Vol. vi.
(1892), p. 80, as R. hystrix var., was described in the Journal of
Botany for 1894, p. 47, under the name R. powellii, nov. sp., or
nov. var. In the new Handbook, Mr. Rogers places it under the
same name as a subspecies of R. rosaceus. It has grown quite
true to type in my Cambridge garden from Essex seed. In
addition to its forest habitat it has been found on Shooter's Hill,
by Major Woolley Dod, R.A., and in Oxfordshire by Mr. G. C.
Druce, F.L.S.
