BOLETUS FRAGRANS, Vitt, A NEW BRITISH FUNGUS. 
By WonruiNGTON G. SurrH, F.L.S. 
(Prate LXXXIV.) 
In the ‘Journal of Botany ’ for February last (page 33) I recorded 
my discovery of this interesting species of Boletus as a British plant ; 
with the present number is given a figure of it, taken by me from the 
fresh specimens. For the description, and full particulars regarding 
its place of growth, etc., reference must be made to the number of 
‘ Journal of Botany ’ before mentioned, where all particulars are given. 
in detail. 
I hope to publish an account of the discovery of several other Hy- 
menomycetous Fungi, new to Britain, in an early number of this 
Journal.

CHENOPODIUM ALBUM, Auct, AND ITS VARIETIES. 
By Hewerr C. Warson, Esa. 
Three principal forms of this plant are distinguished by English 
botanists who have given exact attention to the Okenopodia. The 
same forms are also recognized by the Continental botanists, either 
with or without additional subdivisions. Opinions differ as to the 
three forms being varieties simply, or sufficiently distinct to be ac- 
cepted as true species. It is roposed here to give in some consider- 
able detail a record of two experiments, made under conditions suit- 
able for yielding facts such as ought to guide our opinions. The 
simple facts, by themselves, are only a basis for opinionative inference ; 
the soundness of the inferences therefrom is quite a different matter. 
The three forms will be treated as simple varieties in this paper. 
By Linnæus, two of these varieties were described as separate species, 
under the names of album and viride. Afterwards, botanists came to 
regard these two as forms of a single species ; retaining the name of 
album to designate the species, that of viride to distinguish the subor-
