394 the botanical exchange club of the British isles. 
botanists place it as a glabrous variety. — C. E. S. Mr. While’s 
Mint is peculiar. I cannot name it piperita because of its odour, 
which is said to be Bergamot not Peppermint ; again none of my 
30 specimens of piperita from different British localities have leaves 
so short as these. Is it then M. odorata, Sole, which Syme says is 
synonymous w'wh M. citrata, Ehrh. ? Sole (‘ Menth. Brit.’ p. 21) 
dwells upon the concave, ovate leaves, but makes no mention of the 
glabrous pedicels and calyx, although the plate represents the calyx 
teeth as long, gradually pointed, without hairs, and a much shorter, 
broader capitate inflorescence than Mr. White’s plant. Syme 
E. B.’ vii., p. 12, t. 1029), says of the calyx, “teeth triangular 
abruptly acuminated into long subulate {loints, two thirds the length 
of the tube, glabrous,” but the figure of the calyx shows the teeth 
only about a third of the length. The Somerset plant has a strongly 
ciliate calyx, with teeth above a third the length of the tube, abruptly 
narrowed. As Mr. White says, doubtless the Bergamot Mint varies 
greatly in its inflorescence degrees of hairiness, &c. And this leads 
us to ask whether M. Briquet (‘I.es Labi<;e des Alpes Maritimes,’ 
p. 73) has not made the right suggestion when he puts M. citrata, 
Ehrh. (which he considers to be a hybrid of aquatica) with viridis as 
a sub-species of M. piperita (a plan I have followed in ‘ British 
Plant List ’) ; the super-species itself being a hybrid of the same 
species. Bric[uet dwells upon the oval or oval-oblong leaves 
obtuse at tlie top, sub-cordate at base, and he goes on to say that 
it is united with M. piperita, var. ojjicinalis, by a continuous series of 
intermediate forms. 'Faking this view we may follow Mr. White’s 
lead, and name it M. citrata, Ehrh., but add “forma ciliata," since 
the ciliate calyx, &c., prevent us considering it to be typical. Strail 
(‘Class, de Menthes,’ p. 46) keeps M. citrata, Ehrh., in a separate 
section, i.e. “ Calyx glabrous, tube of the corolla glabrous within. 
Leaves largely oval, sub-obtuse and sub-cordate. Tlie whorls very 
obtuse, often hemisirherical ; ” while the Mint distributed as M. 
citrata, Ehrh., by Schultz (Herb. Normale 581), looks like a I 
glabrous aquatica with more distinctly triangular calyx-teeth. —

M. hirsuta (Huds.). Wet ditch. Waterworks Lane, Cropston, 
Leicestershire, v.-c. 55, Sept. 1908. In great plenty, foliage of a 
pale yellowish green, 3 to 4 feet high. — W. Bell. Yes, I think 
M. aquatica, L., and hirsuta (Huds.). — C. E. S. A state of M. 
aquatica, L. {hirsuta, Huds.). Looks as if it had been grown in 
shade, and under difficulties. — E. S. M. 
M. hirsuta, Huds. Hockley Hole, Leicester, v.-c. 55, Sept. 
1908. Plentiful and extending for upwards of 100 yards on the i 
margin of a small streamlet by the roadside ; foliage very dark and 
inclining to a bronzy hue, flowering plants few. — W. Bell. Seems •
