The principal points which it has appeared to M. De 
Candolle advisable to consider, with regard to the distribu- 
tion of Legiiminosae into natural tribes, are, 1 . the state of 
the embryo as to the division of its radicle, which is either 
curved or straight; 2. the nature of the calyx, whether 
distinctly lobcd or not; 3. the insertion of stamens, whether 
hypogynous or perigynous; 4. the nature of the corolla, 
whether papilionaceous or otherwise ; 5. the aestivation of the 
corolla, whether imbricated or valvular ; 6. the texture of 
the cotyledons, whether thick and fleshy, or thin and 
leafy ; 7. the structure of the legumen ; and, 8. the inser- 
tion of the first pair of leaves produced after germination, 
which are either alternate or opposite. 
By the aid of these characters, he has divided the whole 
order into 11 tribes : viz. 1. Sopliorea, 2. Lote<£, 3. Hedy- 
sareet, 4. Yic'iecE^ 5. PhaseolecB, 6. Dalbergiece, 7. Swart zietE, 
Mimose££y 9. Geoffrece^ 10. Cassiea, 11. Detariece. Under 
these heads are arranged 282 genera, and about 3806 
species. 
A twining shrub, with smooth, angular branches, 
leaflets large, solitary, cordate-ovate, apiculate, netted, 
smooth, not much longer than tlie petiole. Stipules at the 
base of the petiole ovate acuminate, at the base of the leaflet 
ovate acute. Racemes axillary, many-flowered, erect, 
longer than petiole, quite smooth. Flowers bright purple, 
very handsome. ' J. L.
