 oblong-obovate, cuneate at the base, slightly decreasing in size towards 

 the apex of the leaf; stipules subulate, erect or incurved. Racemes 

 shorter than the leaves, sessile, many-flowered. Flowers small, ap- 

 proximated at the base of the raceme, more distant and deciduous 

 towards the apex. Calyx-segments broad, acute. Legumes approx-

 — A decoction of the root used as a lotion effectually destroys vermin ; 

 the juice of the young branches mixed with honey is recommended 

 for aphtha? of the mouth in children; and Indigo in powder, sprinkled 

 on foul ulcers is said to cleanse them. The disease in poultry, known 

 by the name of yaws, is cured by the application of a solution of Indigo 

 by means of a rag. Macfady.fi. jam. \. 251. Indigo is also used in 

 epilepsy, and erysipelas. Med. Gaz. xx. 172. Moreover the valuable 

 dye obtained from it is a highly dangerous vegetable poison. It is, 

 however, by no means confined to I. tinctoria. The following are 

 equally important in regard to their dyeing qualities : —
