 Shady places all over Europe. (Celandine.) 



A biennial. Stem 2 feet high, branched, swelled at the joints, leafy, 

 round, smooth. Leaves smooth, very deeply pinnatifid, their lobes in 

 2 or 3 pairs, the terminal one largest, all rounded, bluntly lobed and 

 notched ; the lateral ones sometimes dilated at their lower margin, near 

 the base, almost as if auricled ; their colour a deep shining green. 

 Flowers bright yellow, umbellate, on long, often hairy stalks. Calyx 

 tawny, often hairy. Seeds black and shining, each with a whitish deci- 

 duous crest. The juice is a violent acrid poison. It has been regarded 

 medicinally as stimulating, aperient, diuretic, and sudorific, it was also 

 considered a powerful deobstment. It is a popular remedy for warts, 

 and has been employed successfully in opacities of the cornea.

 mit, with a green keel to the upper and under petals. Spur very short, 

 rounded. Calyx coloured, toothed, deciduous. Fruit globose, emar- 

 ginate. Herbage bitter, slightly diaphoretic and aperient ; the juice 

 was formerly administered in cutaneous diseases and obstructions of 

 the liver.
