Leaves simple, trifoliolate and imparipinnate. 
I have retained this plant as distinct, but find that it is very 
closely allied to 7. Brassii Baker in the group of the Puacalebe, 
In the structure of the flower the two closely approximate, but 
in I. Dupuisii there is much more marked heterophyllism. In 
z — there is only a slight tendonoy 4 to this. J. pulchra Vi 
var. andongensis Hiern is also a near ally.
