252 ON THE EKGLISH MINTS. 
Pedicel ^-1 line long, naked or slightly liairy with spreading hairs. 
Calyx-tuLe | line long, quite campanulate, the teeth } line long, 
bluntly or rather sharply triangular, as long as broad, covered all over 
with patent or erecto-patent hairs. Nut rough. Corolla reddish 
purple, about twice as long as the calyx, hairy both within and without. 
Scent usually strong and coarse. 
This seems to be, both in Britain, Germany, France, and Scandi- 
navia, the ordinary cornfield form of the plant. Sole's vav. y, accord- 
ing to the autheutic specimens, is a strong erect luxuriant form of this, 
with coarsely hairy leaves and calyx. Smith's var. 8 seems to be a 
diminutive paludal state of the plant with rather sharper calyx-teeth. 
"Var. 2. M. nummularia, Schreb., Borcau, 1951 ; Wirt gen, n. 94. 
Stronger and less branched than var. 1 ; the stem less hairy ; the 
leaves broader, greener, and less hairy, the teeth blunt and shallow, the 
lower one rounded or cordate at the base, the lowest roundish and 
hardly toothed. This appears to be a not uncommon cornfield form, 
and is often labelled M. agredk. 
Var. 3. M. precox. Sole, t. 13. 
Stem strong and upright, hairy above, nearly naked below. Leaves 
ovate, coarse, bluntish, hairy all over with bristly hairs above, paler 
and hairy principally on the veins below. Calyx quite campanulate, 
hairy all over, and the teeth triangular. Pedicel 1 line long, nearly 
naked. This is evidently not more than a robust stream-side form ot 
the plant. 
M 
M. 
P. Schultz?; Wirtgen, n. 92 ? 
Stem erect, much branched, very hairy with stift" deflexed hairs. 
Leaves broadly ovate, rounded or cordate at the base, 2-2|- inches long 
by \\ broad, coarse in texture and somewhat rugose, dull green and 
densely hairy with strong bristly hairs all over above, paler beneath and 
not so haky, the serratures broad and deep. Lower whorls 1 inch 
apai't, upper with leaves twice their length, the pedicel 1-1| line 
long, clothed with deflexed hairs ; tube and teeth together 1 line long, 
the former quite campanulate, the latter triangular, both densely hairy. 
Corolla on tlie outside shaggy. This differs from var. 1 principally 
by its larger and broader leaves, by their deeper serrations, and the 
dense bristly hairiness of the upper surface. I have seen specimens 
from Somersetshire (Sole), Durham (Winch), and Sussex (Borrer).
