2i4* ON THE ENGLISH MINTS* 
move strongly -liairy beneatlij especially on the veins; the serrations- 
bluntish or moderately sharp. Tlowers in a large rounded or oblong 
terminal head, with one or two slightly separated whorls, which are 
surrounded by stalked or subsessile leaf-like bracts. Pedicels 1-3 
lines long, densely clad with strong deflexed hairs ; tube campanulate- 
cylindrical, 1 line to It line long, very hairy; the teeth ^tof of a 
line long, narrowing suddenly above the base to a lanceolate-subulate 
point, and densely hairy. Bracteoles linear-lanceolate, strongly haiiy. 
Corolla purple, about twice as long as the calyx, hairy both within 
and without. Nut veiTucose. Scent usually rather strong. 
Apparently the commonest Mint throughout Britain, and extending 
from the seacoast to Orkney. Mr. Croall finds it up the Dee valley 
to Invercauld, and I have gathered it at 500 yards above the sea-level 
in Torkshire, and nearly as higb in Durham. I have used the name 
hirsuta in preference to aqiiafica, because neither of tbe Linnean spe- 
cimens of the latter are our plant, and part of the description does 
not fit it ; whilst of hirsuta both the specimen and description coincide 
with it. Specimens from Sussex (Borrcr and H. 0. Watson) and 
Surrey (Winch) coincide with the M, ruhro-aqitaticay Wirtgen, fasc, 
2, n. 35; M, Wirtgeniana agnatlca, fasc. 3, n. 46; M. aqnaiica 
pdorata, Fries, Herb, Norm. This has quite the habit of the normal 
plant, but has the lower part of tbe stem and lo\ver petioles quite 
naked, the leaves quite naked abov'e and only shortly ciliated at the 
F 
edge and upon the veins beneath, the pedicel, calyx-tube, and teeth 
hairy throughout, but the hairs only very short, and the corolla slightly 
hairy. This is not the M. odorata of Sole, as Dr. Wirtgen supposes, 
and Eeiclienbach and Boreau are both at fault with regard to Sole's 
plant. The J/, piperita of the Linnsean herbarium, 31, Pimentum of 
Nees vou Esenbeck, is considerably more hairy than this, but does not 
otherwise differ. M. ptirpnrea^ Host, has more widely separated lower 
whorls, and is the first step in the direction of 3/. saliva,

Habit of the preceding. Stem quite smooth, throughout usually 
tinged vvilli purple. Leaves broadly ovate, rounded or cordate at the 
base, deep grecu above, usually more or less tinged with purple, 
sprinkled with glands beneath, but not at all hairy on either side.
