shire, Yorkshire mountains, and these of the Lake district, and is 
plentiful on most of the higher Scotch mountains, as far north as 
Orkney and Shetland. It is abundant on the dry waste flat called 
Morich More, near Tain, Ross-shire, nearly on the level of the 
sea, but is very small in that locality. 
England, Scotland, Ireland. Perennial or Biennial. 
Summer, Autumn. 
Rhizome slender, woody, generally branched, producing rosettes 
of spreading leaves, some of which are barren. Stem from the 
centre of a rosette, 3 inches to 2 feet high, with ascending or 
spreading branches in large specimens. Radical leaves narrowed 
at the base, but scarcely stalked, generally with a few short 
narrowly triangular projecting lobes; stem leaves rounded at the 
base, generally broader than the radical leaves, which are usually 
decayed by the time the pods begin to form ; the uppermost, which 
are the broadest, having sometimes short auricles. Flowers white, 
about § inch across. Petals rather more than twice as long as the 
sepals, obovate with a small notch at the apex so as to be obcordate. 
Fruit pedicels 7’; to 3 inch long. Pods + to} inch long, twice anda 
half to six times as long as broad, usually making one complete turn 
upon its own axis, but sometimes only half a turn; style scarcely 
longer than broad. Seeds very numerous, pale reddish brown, 
ovate, scarcely compressed, very finely punctured. Whole plant 
greyish or whitish green; the leaves more or less covered with 
stellate and simple hairs, and ciliated at the edges. Stem and 
axis of the raceme and pedicels white, on account of the close 
covering of short hairs. 
The form with stellate hairs on the pods, D. confusa (Ehrh. non 
Reich.), appears to be scarce in Britain, as the only specimen I have 
seen of it is one from the Botanical Society of Edinburgh, labelled 
“‘Clova, Forfar. Dr. Balfour, 1846.”
