downy all over, rarely glabrous. Pedicels hispid, with spreading 
hairs. Pod sometimes hairy, but usually with only small raised 
vesicles resembling scales when dry. 
The style should be examined in mature pods, as it considerably 
exceeds the notch until the wings are fully developed.

Rootstock woody, simple, or branched at top. Stems numerous, 
ascending. Radical leaves oblanceolate or elliptical, attenuated 
at the base into a footstalk; stem leaves (except the very 
lowest) sessile, amplexicaul, oblong or lanceolate; all entire or 
toothed, with long acute sub-parallel auricles. Petals rather more 
than half as long again as the sepals. Stamens 6. Pod sub- 
rhomboidal - ovate, glabrous or with a few small inconspicuous 
vesicles; valves keeled from the base to the apex, where the wings 
are broadest and project into a sub-triangular rounded lobe on 
each side of the style, separated by a broad shallow notch ; 
style twice as long as the notch. Seeds prismatical-ovoid, coarsely 
punctured. 
In pasture fields and waste places, and by roadsides. Not 
uncommon in England; and in Scotland more common than 
L. campestre, reaching as far north as Morayshire and Dumbarton- 
shire. 
England, Scotland, Ireland. Perennial. Spring, Summer. 
Very like L. campestre, but the woody rootstock produces 
many more stems, from 6 to 18 inches long, decumbent at the 
base and curving upwards at the extremity, where they are fre- 
quently corymbosely branched. The stem leaves are shorter, more 
sagittate at the base, and generally more distinctly toothed; the 
flowers larger ; the anthers violet. The pods are extremely similar, 
but in the present species a little more narrowed towards the base,

of L. hirtum omitted.
