XLIV.—On the British species of Plumbaginaceee. By Cuar.es 
‘ C. Basineton, M.A., F.L.S., F.G.8.* 
Tue publication of the 12th volume of DeCandolle’s invaluable 
‘ Prodromus,’ in which the description of the Plumbaginacee by 
M. E. Boissier is contained, has again drawn my attention to our 
native species included in that order, upon which I formerly be- 
‘stowed considerable study, but without arriving at any satisfac- 
tory result. With the help of Boissier’s descriptions I have now 
re-examined all the British specimens which I have been able to 
obtain, and although the result is far from being such as I could 
have wished, still it seems desirable to place it before botanists 
in order that their attention may be turned towards these plants, 
and thus some definite conclusion may perhaps be obtained.

Boissier does not seem quite satisfied concerning the perma- 
nency of some of the characters upon which the species of Ar- 
meria are founded, and it must be confessed that the result of my 
examination of our plants has not tended to increase any little 
dependence that I placed upon them. The characters to which 
I refer are those taken from the relative lengths of the pedicels 
and calyx-tubes, and the presence of hairiness upon the angles 
alone of the latter or over its whole surface. 
I have however thought it desirable to characterize the possible 
species by employing distinctions derived from those parts as well 
as from others, in ‘order that they may correspond with the 
species adopted in the ‘Prodromus.’ I shall then notice two 
other specimens of which I am in possession; and also make a 
few remarks upon a possible mode by which the supposed species. 
might be combined if the doubtful characters were neglected.
