 Silique large, tumid throughout, subcylmdrical, corrugated, 2.7 



cm. long, the articulation hori- 

 zontal, strongly lipped. Upper 

 joint subcylindrical, tapering to 

 a somewhat pugiform apex, 1.6

Stems thick, axis of fruiting 

 raceme very stout and strongly 

 geniculate, pedicels stout. 

 Leaves lanceolate, blunt, taper- 

 ing to a short petiolar base, 



sparingly, blunt and distant, large-crenate toothed. Dr. Robinson, 

 in describing the type from which the above characters are drawn, 

 says: "Foliage of the type," but in so stating he considers our 



The cuts present: An enlargement of the fruit; a section of the upper and the lower joints; 

 the seed, and a transverse section showing the arrangement of the cotyledons. The enlargements 

 .are relatively the same in all the cuts.
