ON THE ENGLISH MINTS. 245 
Flowers in a rounded terminal head, with one or two slightly separated 
whorls subtended by leaf-like bracts. Calyx purplish ; the tube and 
teeth similar in shape and dimensions to those of the preceding, but 
both these and the bracteoles are quite naked. Corolla twice as long 
as the calyx, naked both within and without. Nut smooth. Scent 
aromatic, citron-like. 
This seems to me quite connected with the preceding by the inter- 
mediate forms above referi'ed to. I have seen it from only one British 
station where it is at all likely to be wild, a ditch near Bedford, where 
it was gathered by the Eev- C. Abbott, from one of whose specimens 
the E. B. 1025 figure was drawn.

Stem 2-3 feet high, erect, firm, quadrangular; branched below, 
with erecto-patent branches when luxuriant, thinly hairy, with deflexed 
hairs, or sometimes naked below, often purplish. Leaves all sessile, 
or the lowest very slightly stalked, resembling those of M. viridis in 
appearance and texture, lanceolate or ovate-lanceolate, the lowest from 
2-3 inches long by about an inch broad, the lower part narrowed 
gradually and the point acute, the upper surface deep green and naked, 
the lower paler and glandular but only slightly hairy on the veins ; 
the serration sharpish, but distant and not deep. Whorls all above 
the centre of the stem, the upper ones nearly an inch apart, the leaves 
of the lowest 1-2 inches long, and of the upper ones at least twice as 
long as the whorls. Pedicel ^f line long, not hairy, but rather 
glandular, and often purple. Calyx-tube nearly a line long, campanu- 
late-cylindrical, glandular all over, but only the upper hairy. Teeth 
\~^ line long, lanceolate-subulate, densely hairy, with erecto-patent 
hairs. Bracteoles linear, slightly ciliated. Corolla reddish-purple, 
only about half as long again as the calyx, naked both within and 
without. Scent of M. viridis.
