under B. vulgaris in having the terminal lobe of the leaves much 
smaller in proportion to the lateral leaflets, which are also more 
numerous. The leaves, at the base and middle of the stem 
especially, present a remarkable difference, being lyrately pinnate, 
with several pairs of leaflets wider from tip to tip than the ter- 
minal lobe, which is ovate, sub-rhomboidal or occasionally wedge- 
shaped with a few lobes at the tip. Boreau states that the petals 
“slightly exceed the calyx;’ but in the Lancashire and Cheshire 
specimens in my possession they are rather more than twice as 
long. The pods are applied to the axis of the raceme as in 
B. stricta, but are shorter and with shorter pedicels. The seeds 
are larger than those of B. stricta and B. arcuata and much 
broader, broader even than those of B. eu-vulgaris.

Radical leaves lyrate with the terminal lobe largest, roundish or 
ovate, equalling in breadth the width of the leaf measured across 
the uppermost pair of leaflets, and generally twice or thrice the 
length of one of them; stem leaves pinnate, the upper ones 
pinnatifid with long slender lateral lobes, and a terminal one a 
little larger than the others. Flowers inashort laxraceme. Petals 
about thrice as long as the sepals. Pods in a very lax raceme, 
spreading-ascending, twelve to twenty times as long as the pedicels, 
and very slightly exceeding the pedicels in thickness, contracted at 
the tip into a style considerably shorter than the greatest width of 
the pod. Seeds nearly as broad as long. 
Roadsides and newly-trenched ground, in many places in 
England and some in Scotland, but no doubt escaped from 
cultivation; this plant being the American Cress often cultivated 
as a spring salad.

The very long distant spreading pods with their very short 
style distinguish the present plant from all of those included under 
B. vulgaris. It, however, presents considerable resemblance in 
the leaves and seeds to the sub-species B. intermedia, but that
