work of the world. The circulating museum, if properly used, may
become an unspeakable boon in educating and edifying the children ;
in drawing-out their observational faculties and building-up their
reasoning powers. If the Essex Field Club's Museum will aid in
such a work, every educational realist will admit that it will not be
simply benefiting the children and teachers in this or that village—it
will be indirectly elevating the entire county.
EPPING FOREST RUBI.
By J. T. POWELL.
PART II.—ADDITIONS AND CORRECTIONS.
TWO more seasons among the Forest brambles have resulted in
several additions to the list given in the Essex Naturalist
for 1889 (Vol. iii., p. 20), as well as some revision of that list.
I have again been greatly indebted to Prof. Babington for his aid
in determining difficult forms, and more particularly this year have I
been helped by the Rev. W. Moyle Rogers, F.L.S., one of our best
batologists, who has not only named the specimens sent to him
through the Watson Botanical Exchange Club, but has in the kindest
manner rendered me invaluable personal assistance.
Mr. Rogers refers to R. rhombifolius, Weihe, a bramble which
occurs abundantly about Walthamstow and Snaresbrook, and which
I formerly placed under R. rhamnifolius. We have also plenty of
the robust rhamnifolius of the English authorities. A form near
villicaulis Mr. Rogers identifies as R. pyramidalis, Kalt. This occurs
sparingly at and near High Beach. The bramble previously recorded
as R. sertiflorus, P. J. Mull, is believed by the same authority to be
a hybrid, probably rusticanus x pyramidalis, in which case the name
sertiflorus must be cancelled. A very distinct form of macrophyllus
has been named by Prof. Babington, R. amplificatus, Lees. This
occurs at Leppitt's Hill, Buckhurst Hill, and near High Beach.
The professor has also given the name R. plinthostylus, Genev., to a
bramble from Hawk Wood, Chingford, which I had included under
Koehleri. R. sprengelii, Weihe, recorded in 1886 by Mr. J. G.
Baker, I have found to be one of the most widely-spread of the
Forest Rubi.
