Tree 15 to 20 ft. high ; bark white or grey ; twigs, petioles and inflores- 

 cence velvety. Pinnae in 10-40 pairs, 2-6 cm. 1. ; leaflets in 30-50 pairs, 

 linear, somewhat acute, 3-7 mm. 1. Large elliptical gland on petiole, and 

 smaller ones at the base of some of the pairs of pinnro. Spikes 7-10 cm. 1. 

 Flowers white, changing to pale yellow. Calyx 2 mm. 1., densely pubescent. 

 Corolla 3(-4) mm. 1. Pod 7-12 cm. 1., 1-3-1 -8 cm. br. 



This species has been generally known as A. catechu Willd. by authors 

 including Bentham (1842), but the latter botanist has, in his monograph 

 on the Mimosese, correctly assigned the name A. catechu to the species 

 with fe^ver leaflets (20-30 pairs), the corolla 2-3 times as long as the calyx, 

 and the bark brown. Both species yield cutch. 



Cutch or Catechu is prepared by boiling down a decoction of chips of 

 the heart-wood, and is especially valuable as an astringent in chronic 

 diarrhoea and dysentery. The wood seasons well, takes a fine polish, and 

 is extremely durable. It is not attacked by white ants or toredo. It is 

 used in India for oil and sugar-cane crushers, agricultural implements, and 

 wheelwrights' work. A cubic foot weighs about 70 lbs. (Watt).]
