SALVIA MARQUANDII, sp. yn. 
By G. Cuarnmwwex Druce, M.A., F.L.S. 
(PiatE 483.) 
In June and July last I visited the Channel Isles, one of my 
chief objects being to clear up the mystery connected with Salvia 
clandestina, I made a careful search in Jersey, but saw there onl 
S. Verbenaca, which showed no definite Mosinee except that caused 
by difference - soil and exposure. But in July, whilst in the 
company of . D. Marquand, the wraliicnoiin naturalist and 
author of the saniidieaik Flora of Guernsey, I noticed growing in 
grass on light sandy soil at Vazon Bay, in Guernsey, ; 
which I at once saw was new to me and obviously distinct from 
S. Verbenaca or the true clandestina, which I have seen in its classic 
eens It appeared to be limited to a small area, although we 
earched somewhat diligently nastig the north coast; nor could 
i see it in Alderney, where S. Verbenaca is such a conspicuous 
feature. 
The history of the plant which has been called S. clandestina in 
Britain dates from the publication of Babington’s Primitie Flore 
Sarnice in 1839, shi’ the spr records it from near Pontac and 
uer 
bela ae all ee ee of Verbenaca only; I believe Mr. Pugsley 
has come to the same conclusion, and this, too, was Syme’s view. 
At the d date atlases vege Seen am only Sigers’! begun ad work 
on the British Flora, and did n m to be aware what was the 
true clandestina of Pinions: te paises his Channel faautis ‘hint 
doubtfully to that species, but quotes Bentham, who had materially 
widened the definition of that plant from that covered by the 
rng ate in the Species Plantarum. Babington does not seem to 
e been aware that Smith’s clandestina was still a different 
idiad: while he tried to obtain specific ge from the leaf- 
characters, which I think, notwithstanding M. Briquet’s monu- 
mental work on the Labiate, where moieties is attached to this 
character in differentiating the Salvias of this ‘sscubieia can scarcely 
be so valuable as those drawn from the shape and colour of the 
C ] 
the later editions of Babington’s Manual, but they do not fit the 
restricted plant, and it is difficult to believe he had the true species 
before him, nor do they agree with the Guernsey plant. 
In the th 
S$ seen 
the Borrer Herbarium, gathered in Guernsey, as S. a and 
this is, I think, identical with the ak which I am about 
describe. The figure, t. 1057, is rather poor, and thot colouring 
bad, as our plant has clear blue (beau bleu), not purplish flowers.
