Tribe 4. Lotece B & H. Gen. 442 Herbs rarely shrubby, 

 with one to many-foliolate leaves, entire leaflet*, foliaceous. scarious or

 IFOSACKIA Benth. and American, authors. 



Herbaceous or suffrutescent plants with pinnately one to sev- 

 eral -foliolatc leaves with gland-like, rarely scarious or foliaceous, 

 stipules and one to several-flowered axillary peduncles, the flower 

 often suhtended by a 1-5-foliolate bract. Calyx o-toothed or 

 -cleft, the teeth nearly equal, usually longer than the tuhe. 

 Petals free from the stamens, nearly equal, the upper one ovate 

 or roundish, lateral ones obovate or oblong,, keel somewhat in- 

 curved, obtuse or acutely beaked. Stamens diadelphous ; the 

 alternate filaments dilated or thickened under the anthers. Pods 

 linear, compressed or terete, straight or arcuate, sessile, dehis- 

 cent or indehiscent, 1 -several-seeded, with spongy partitions be- 

 tween the seeds. Seeds variously rounded or elongated, some- 

 times quadrate, smooth, tuberculate or" rugose.

 i'oliolate nearly sessile leaves with small gland-like stipules and 

 small flowers on axillary peduncles. Petals but little exceeding 

 the calyx the claws equally approximate to each other., keel nar- 

 rowed above into a rather short, acute, incurved beak, equalling 

 or exceeding the wings: pods linear, straight or nearly so, some- 

 what compressed, readily dehiscent, several-seeded.

 high, simple to diffusely branched : leaves nearly sessile or short-petioled ; 

 leaflets ovate to lanceolate or oblong, 3-9 lines long often only the terminal
