172 ENGLISH BOTANY. 
measured across the uppermost pair of leaflets; uppermost leaves 
oval, deeply and irregularly toothed; all dark green. Flowers in 
a raceme, the length of which generally scarcely exceeds the breadth. 
Petals twice as long as the sepals. Pods in a dense raceme, generally 
ascending, sometimes spreading when young, three to six times as 
long as the pedicels; seeds with their length about once and a half 
their breadth. 
Hedgebanks, roadsides, and by the edges of streams and ditches. 
Common throughout the kingdom, extending in Scotland as far 
north as Morayshire. 
England, Scotland, Ireland. Biennial and Perennial. Summer. 
Stem erect, angular, 1 to 3 feet high, much branched in the 
upper part. Radical leaves in a rosette, pinnate, lyrate, with 
6 to 10 leaflets, of which the terminal one is usually much larger 
than the others, and the lateral ones decreasing in size towards the 
base; lower stem leaves resembling the radical leaves, but with 
enlarged ciliated auricles at the base of the petiole which embrace 
the stem; intermediate leaves pinnatifid with a large toothed 
terminal lobe, and a few narrow lateral ones amplexicaul at the 
base with pointed auricles ; uppermost leaves with a few irregular 
blunt teeth and sagittate-amplexicaul at the base as in the lower 
leaves. Flowers about + inch across, bright yellow; sepals oval, 
yellowish ; petals oblanceolate; pedicels about § inch long. Pods 
3 tol inch long; seeds yellowish brown, shortly oblong, irregularly 
plano-convex, covered with raised points having a tendency to run 
into lines. Foliage deep green, shining and glabrous, rarely with 
a few hairs. Radical leaves in this as in the other forms usually 
decaying by the time the flowers expand. 
A form with the young pods arched and spreading occurs in 
shady places. It has often been mistaken for B. arcuata, but is 
apparently merely a state of B. eu-vulgaris. It is this plant which 
is figured by Reichenbach, in Sturm’s ‘ Deutchlands Flora.” The 
true B. arcuata is, however, figured by him in his “ Icones Flore 
Germanic et Helveticz.”
