THE discovery of this plant in Britain by Prof. T. G. Bonney, 
F.R.S., is oneof considerable interest to Botanists, not only because 
it adds one more species to the British Flora in a genus we might 
scarcely expect to find a further novelty, but chiefly on account 
of its hybrid origin and its rarity on the continent, where, so far 
as I can learn, it appears to be local, having been found only in 
a few parts of Germany, viz. :—in the island of Wollin on the 
coast of Pomerania; Forest of Jungfernheide, north of Berlin ; 
near Charlottenberg ; Auhlan Pomerania, Forest of Stadtforth 
Hodeheide; Czarinkau in Pomerania; many places of the Nieder 
Lausitz ; Province of Brandenburg, i. e. Sommerfeld, Dobrilugk ; 
in Silesia near Nierky, Naumburg on the Bober; on the Konig- 
hanier Berge near Gorlitz. 
(For the above list of localities I am indebted to Mr. A. Bennett, 
of Croydon, who kindly procured them from Dr. Karl Schumann, 
the Keeper of the Berlin Herbarium.) 
It was first gathered by Prof. Bonney, in August 1886, on 
Cannock Chase, where it is plentiful in certain spots, V. Myr- 
tillus and V. Vitis-idea being also abundant. It is accepted by 
continental authors as a hybrid between these two species ; 
and from the evidence gathered by. Prof. Bonney, and from the 
fact that its assumed parents grow in the same locality with it, 
there can be no doubt that this view is correct. And I do not 
doubt that the plant has originated independently on Cannock 
Chase, and has not spread to that locality from the continent. The 
plant appears to produce fruit but rarely, Prof. Bonney, so far as 
is known to me, only having found two berries, although the plant 
covers a considerable extent of ground. It will be interesting 
to determine how far the plant comes true from seed, or if it has 
a tendency to revert in any way to its parent forms. 
It is possible that this novelty may exist undetected in other 
localities, as its general resemblance to V. Myrtillus may have 
caused it to have been overlooked. The best means of detecting 
the plant superficially appears to be by its evergreen habit; but
