138 ERICA CARNEA, LINN., GATHERED IN DEVON. 
and arrested before reaching the extreme west of Europe, E. mediter- 
ranea is a normally occidental species, having a very restricted area, 
and usually, I believe, growing within the influence of a maritime at- 
mosphere. The absence of E. carnea from Trance, and of E. medi- 
terranea from Italy, is very anomalous, and apparently inexplicable, 
since both countries, from geographical position, extent, and varied ac- 
cidents of surface, would seem to afford localities well adapted to the 
requirements of these species. I may also note, in reference to Mr. 
Watson's remark, that in Dalraatia both plants appear to grow under 
similar conditions both of climate and situation. 
On comparing the Devonshire plant with the Irish one, and with a 
Tyrolese specimen from Mr. Baker, and a Savoy one collected by 
Huguenin, of E. carnea, it is evident that it agrees rather with the 
latter; — the corolla being constricted at the throat, the anthers entirely 
exserted, and the leaves — some of which are conspicuously keeled, 
whilst others are as evidently furrowed beneath — having the decurrent 
line from their base distinctly prolonged to the second whorl beneath 
them. I fear, however, that implicit reliance cannot be placed on the 
two last characters, which Professor Babington gives as diagnostic, for 
in E. carnea the median keel of the leaves, though apparently always 
distinct at the base, sometimes gradually merges into a furrow about 
halfway up, and the ridge also occasionally ceases at the nearest in- 
ferior verticil. Nevertheless, the shorter, wider, open-mouthed corolla, 
and semi-included anthers of the Irish species give the flowers so very 
distinct an appearance, that I do not think the two could well be con- 
founded. 
It cannot, of course, be expected, after the length of time that has 
elapsed since I gathered the plant to which this notice refers, that 1 
should be able to give any perfectly reliable information regarding it- 
I have unfortunately only preserved a single specimen, — though my 
impression is it was not particularly rare in the locality where it grew, 
and this specimen is marked as decidedly wild. So much mischief, 
however, arises from the careless practice of recording as native mani- 
festly introduced plants, whose tenure of a recorded station, even when 
they are abundant there, is often quite ephemeral, that I wish distinctly 
to disclaim attaching any importance to my memorandum of spon- 
taneity,— my object in writing this paper being to induce search in the 
locality.
