footstalks of the segments are mostly dilated on one side at the base, 

 sometimes into a leafy expansion, a dark shining green above, glaucous 

 and smooth, or hairy beneath. Floivers a bright yellow, in small 

 lateral simple umbels, not very numerous, and the common stalk is 

 smooth or hairy, as are the partial ones, which are surrounded at the 

 base, with obluse membranous scales. Calyx of two oblong semi- 

 membranous scales, concave, and falling off as the flower expands. 

 Petals roundish, wedge-shaped. Stamens with the filaments dilated 

 upwards. Stigma small, two lobed. Pod linear, cylindrical, pointed 

 at the base and towards the apex, one celled, two valved, bursting from 

 the bottom. Seeds numerous. 



Habitat. Waste places, banks, and hedges; frequent, /3. Wim-

Perennial ; flowering in May and June. 



The whole plant abounds in an acrimonious yellow coloured juice, 

 which has been used for the cure of various diseases of the skin in the 

 form of infusion or decoction, and the juice is still used by country 

 people to destroy warts, ringworms, and tetters ; and diluted with milk 

 it is said to have been used with advantage in removing specks from 

 the eyes. When the infusion or decoction of either the herb or roots 

 is taken it must be with caution, as its acridity is liable to cause con- 

 siderable irritation of the bowels. It has been considered useful in the 

 cure of jaundice, and perhaps the very irritation which it causes may 

 in some cases have been useful.
