Rootstock shortly creeping. Tadical leaves few, with smaller 
leaflets than those of the stem leaves. Stamens 6. Young pods 
usually not rising above the corymb of flowers. Style equal to or 
a little longer than the breadth of the pod. 
In damp shady woods and by the sides of streams. Not 
uncommon, and probably distributed throughout the whole of 
Britain, but often not distinguished from C. eu-hirsuta. 
England, Scotland, Ireland. Biennial or Perennial. 
Spring and Summer. 
This plant differs from C. eu-hirsuta by the absence of a tap-root, 
and the presence of a rootstock thinly clothed with root fibres. Stem 
usually taller, more leafy, and the stem leaves having the leafiets 
though narrower in proportion to those of the radical leaves 
actually exceeding them in length, being sometimes {$ inch long. 
The flowers are generally larger, and the whole plant smoother and 
more shining than C. eu-hirsuta. 
When this plant is luxuriant, it sometimes resembles C. amara, 
from which, however, it may always be distinguished by not having 
the large spreading petals and long slender style of that species. 
Sometimes it flowers the first year, and then the tap-root remains, 
as in C. eu-hirsuta.
