E. scotica Wettst. Moel-yr-bgof, Carnarvonshire, v.c. 49, 
Sept. 3, 1924, Growing with Sphagnum, etc., at alt. c. 2000 ft. 
— D. G. Catcheside. This has the facies of a small form of 
E. scotica , but it differs by its shaggy, white pubescence, and 
should be referred, I think, to E. curta f. piccola Townsend. 
Vide Journ. Bot. xl. 362 (1902). — H. W. Pugsley. I agree with 
Mr. Pugsley that this is E. curta f. piccola Towns. — W. H. 
Pearsall. 
E. Rostkoviana Hayne. Shalford Common, Surrey, Aug. 22, 
1925. — I. A. Williams. The smaller-leaved plants were growing- 
in ranker grass than the others. I have taken what I believe to 
be this species also at Little Frensham, in the Punch Bowl, and 
at Worplesdon, so it appears to be common in Surrey. — I. A. W. 
The usual Surrey form of E. Rostkoviana. — H. W. Pugsley 
E. Kerneri Wettst. Grassy waste ground by pathway, Carn- 
kief, Perranzabuloe, Cornwall, v.c. 1. Aug. 5, 1925. — F. Rilstone. 
E. nemorosa, the foliage of the smaller specimens resembling that 
of E. confusa. — H. W. Pugsley. Rightly named, 1 should say. 
The very thin texture and long narrow acute teeth of the foliage 
are against E. nemorosa. The protruding styles of some flowers 
support this view. — W. H. Pearsall. 
Mentha piperita L. a officinalis (Hull.). In water by the 
Upper Frome, Gurney Slade, N. Somerset, Sept. 11, 1925. 
Growing with M. longifolia and M. aquatica. A few examples 
from a new locality. M. piperita is of exceptional interest on 
account of its obscure origin and remarkable stability. A hybrid 
with one parent alien to Britain, it must certainly have been 
introduced from abroad at some remote period. In no country 
has it been shown to be indigenous, but its cultivation as an 
officinal cordial and carminative of high repute has long extended 
throughout Europe. An old writer (Woodville) says that, only 
in Britain does it occur spontaneously — a remark that may still 
hold good. In the dozen or so localities (for officinalis ) known to 
me, although often within sight of dwellings, this Mint is never 
found in company with adventive species, but has always the as- 
pect of a true native, associated usually with longifolia , aquatica, or 
sativa. Another noteworthj^ feature of British Peppermint as a 
denizen is the absence of variation. We have merely the two 
distinct forms officinalis and vulgaris. Very rarely has there been 
reported anything in the wa}^ of an intermediate between these. 
I know of none existing, nor do any appear in our Catalogues. 
The var. Druceana Briq., recently described, evidently leans
