 short. Leaflets 9-11, oblanceolate, J in. long, 1 line broad, mucronate, 

 the lateral ones opposite, nearly sessile, both sides green, very slightly 

 silky. Flowers in close nearly sessile axillary clusters of about 6

 Flowers solitary or 2-4 together in sessile clusters in the axils of the

 Most like /. sessiliflora, but more shrubby, with fewer flowers in a cluster, and a 

 different pod.

 woody, erect, copiously branched, the branches erecto-patent, coated

 2-4 together on peduncles about \ in. long. Pedicels cernuous, gene- 

 rally longer than the calyx, which is 1 line deep, silvery, campanulate,
