Stamens as many or twice as many as petals, inserted on the margin or on 

 the outside of a fleshy disk. Filaments naked, subulate or filiform. Anthers 

 ^-celled. Ovary free, 2-5-celled, ovoid or globose ; stigma subsessile or 

 style short, thick. Ovules geminate (solitary in Hemprichia ?). Fruit dru- 

 paceous or capsular. Seeds exalbuminous. Cotyledons usually thin and 

 more or less contorted ; radicle superior. — Trees or shrubs, often resiniferous. 

 Leaves alternate, exstipulate, 3-foliolate or imparipinnate, rarely unifoliolate.

A small genus of N. tropical Africa and India, including several species affording resins 

 is m° n ! U i erc,al Value - but which our material does not suffice to identify aud describe. It 



most desirable that specimens should be obtained in leaf, flower, and fruit, with samples
