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. 
Cone throughout the kingdom, eas in Scotland as far 
north as duleesy shin: . 
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 2 + inch across, bright yellow ; sepals oval, 
yellowish ; petals oblanceolate ; pedicels about 4 inch long. Pods 
#to1 inch long; seeds yellow ish br own, 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 i is, however, figured by him in his “ Icones Flore 
Germanice et Helvetice.”
