Petals longer than the sepals. Pods reniform, much compressed, 
emarginate at the base, but with a pyramidal point at the apex, 
with a furrow between the valves, but not didymous ; valves not 
deciduous, their surface rugose, with prominent waved ridges, 
which project beyond the edges of the valves, forming compressed 
tubercles, and these ridges are generally connected by smaller 
transverse wrinkles; style forming the apex of the pyramidal point. 
In waste ground and by roadsides. Common in the South and 
East of England; rare in Scotland, where it is confined to the 
coast, reaching its northern limit in Moray and Wigtonshire. | 
England, Scotland, Ireland. Annual or Biennial. 
Stems all lateral, prostrate, spreading, somewhat dichotomously 
branched towards the extremity, 2 to 12 inches long. Leaves 
stalked, deeply pinnatifid (almost pinnate) ; segments of the radical 
and lower stem leaves obovate or oblanceolate, divided into short 
lobes principally on the side directed towards the apex of the leaf, 
those of the upper leaves narrower and more entire. Inflorescence 
in sessile corymbs, one (the central axis) in the middle of the stems, 
the others opposite the leaves. Flowers white, <5 inch across ; petals 
one-fourth as long again as the sepals, which are more persistent 
than in S. didyma; stamens generally all perfect. Fruiting raceme 
very short and dense ; pedicels spreading, 3'5 inch long, very thick. 
Pods } inch long by % inch broad, varying (even on the same plant) 
in the degree of prominence of the ridges, and the presence or 
absence of connecting cross wrinkles; when these are present, the 
surface is honeycombed ; the furrow between the valves deeper on
