little or no cultivation. In Hawaii where the plant was casually in- 

 troduced it has run wild on dry scrublands (Hutchins, Rep. on 

 Forestry, B.E. Afr. 1909, p. 9). The chief requirements are a hot 

 climate with a comparatively low rainfall, and deep soil ; and it 

 would probably succeed well in Northern Nigeria, more especially 

 towards the extreme north.

Katagum ; Nupe ; Lagos, extending through Tropical Africa to

Wood hard but too small to be of much practical use (Medley 

 Wood, Natal PI. iii. p. 20), except for fuel. 



The plant is used for hedges at Gondokoro station (Dawe, Rep. 

 Bot. Miss. Uganda, 1906, p. 34). 



A handsome decorative plant. 



Grows in the coast regions and in dry places, dense low forests 

 being sometimes composed exclusively of this plant in Angola 

 (Hiern, Cat. Welw. Afr. PL i. p. ] 94) ; common in dry hilly places, 

 and in groves of Adansonia, forming at times dense thickets near 

 Loanda (I.e. p. 308) where it attains a height of 8 feet (Gossweiler, 

 Herb. Kew).
