174 ENGLISH BOTANY. 
usually considerably exceeding in breadth the width of the leaf 
measured across the uppermost pair of leaflets ; uppermost leaves 
oval, irregularly toothed; all dark green. Flowers corymbose. 
Petals about one-fourth longer than the sepals. Pods in a dense 
raceme, erect even when young, four to six times as long as the 
pedicels. Seeds nearly twice as long as broad. 
Local. Plentiful in Yorkshire, and it also occurs in Northamp- 
tonshire and Essex. 
England. Biennial? Summer. 
Radical leaves with the terminal lobe much longer than in the 
two preceding plants; the sepals narrower; the petals shorter, 
narrower, and paler yellow; the fruiting raceme longer and more 
slender; and the branches of the stem less spreading than in either 
B. eu-vulgaris or B. arcuata. Seeds about the length of those of 
the latter, but broader.

Radical leaves lyrate, with the terminal lobe oval or ovate, not 
exceeding in breadth or even somewhat narrower than the width 
of the leaf measured across the uppermost pair of leaflets; stem 
leaves pinnate, the upper ones pinnatifid with long slender lateral 
lobes and a terminal one a little larger than the others ; all yellowish 
green. Flowers in a raceme, the length of which is about equal to 
the breadth. Petals about twice as long as the sepals. Pods ina 
dense raceme, erect even when young, four to six times as long as 
the pedicels. Seeds very nearly as broad as long. 
In clover fields near Manchester; also near Bowdon, Cheshire; 
Bilsdale, Yorkshire; near Armagh, Ireland; and Mr. J. G. Baker 
has seen it near Dorking, Surrey; but, as in all cases it is found 
in cultivated fields, it is not improbable that it may have been 
introduced from the Continent with clover seed.
