Calyx 5-cleft ; segments acute. Vexillum roundish, emarginate: keel fur- 
nished with a subulate spur on both sides, at length often bending back elas- 
tically. Stamens diadelphous (9 and 1). Style filiform, glabrous. Legume 
continuous, one or more seeded, 2-valved. Seeds usually truncated, sepa- 
rated by cellular spurious partitions.—Herbaceous or shrubby. Stipules small, 
free from the petiole. Peduncles axillary. Flowers racemose, purple, blue, 
or white ; many of the upper ones of each raceme frequently becoming abor-

The legume of Hedysarum cuneifolium of Roth (€ )nobrychis cuneifolia, DV., 
appears Eo belong to this plant ; but we cannot - the remainder of his de- 
scription to any of the order with which we are acquainted : perhaps it is 
drawn up from fragments of different plants. 
§ 2. Racemes sessile, short, dense, and somewhat capituliform : flowers almost sessile : 
legumes 1-2-seeded, globose or short-oblong, the length not exceeding twice 
the breadth.—Brachycarpe.
