the species which are analogous to them. Thus a great many forms 
have been developed from 2. tomentosus, ay which is prevalent 
of 
in the outh of Europe, and many of the e forms are analo ogous to 
species ceeeine in the Middle of nee And therefore they are 
suspected to be hybrids between these species and tomentosus, 
Borkh. On the other a if the analogy be extended si all the 
these 
analogous forms to make uw) a single species. It has ayohilens seemed 
surprising to many that one author believes 2. thyrsoideus, Wimm., 
to be intimately connected with &. tomentosus, Borkh. ; another with 
R. discolor, Whe. ; and I myself incline to the opinion that 2. thyr- 
soideus from the North of Europe is very a et to R. corylifolius, 
Sm. All these different opinions are to a certain de egree correct, 
but authors have had ifferent though analogous forms in view. 
d from 2. 
discolor, Whe.; that of the South of Europe from 2. tomentosus, 
Borkh.; and the North European 2. thyrsoideus from R. coryli- 
folius, Sm. 
I believe, ierehee, that I have reason for supposing R. suberectus, 
Ands., neither to to the same type as R. Ideus, L., nor to be 
ave 
Jdeus, are real hybrids, produced by these species. For they have 
the more important characters of both R. cesius, L., and R. 
between which they oscillate, if I may so speak, o: such an extent 
that they graduate now into one, now into the other, of the parents. 
Usually the fruit is dark, but I have fepni. it on the true R. pseudo- 
Ideus, Whe., to be crimson, and to separate from the receptacle, as 
in R. ‘Tdaus, L.; the flavour of its fruit is, however, the same as in 
R. cesius. 
By these remarks I ate intended to show that the species in
