Trees with spreading unarmed branches. Leaves bipinnate. Leaflets numerous, 

 relatively small. Flowers borne in lax racemes. Sepals 4. Petals 5, but 2 of them 

 rudimentary. Stamens 3, the filaments united to about the middle, alternating with

1. Tamarindus Indica L. A tree with wide-spreading branches. Leaves 1-1.5 

 dm. long: leaflets 18-36, 1-2 cm. long, the blades oblong to linear-oblong, reticulated: 

 sepals 10-12 mm. long: petals yellowish or reddish, 13-16 mm. long, crisped: pods

4. Medicago minima L. Foliage downy. Stem and branches diffuse or 

 prostrate : leaflets 3, the blades broadly or narrowly cuneate, 0.5-1.5 cm. long, rounded 

 or truncate at the apes, denticulate above the middle: calyx pubescent, 2. .5-3 mm. 

 long; lobes as long as the tube or longer: corolla yellow, 3-4 mm. long: pods closely 

 twisted into 4 or 5 coils, 5-8 mm. broad, the edges armed with toothed prickles. — 

 Differs from M. Arabica and M. denticulata, in the downy stems and branches and the 

 entire or shallowly toothed stipules. 



In dry or sandy soil, North Carolina and Texas. Naturalized from Europe. Spring. 



5. Medicago sativa L. Foliage sparingly pubescent. Stems decumbent or 



ascending, 3-6 dm. long: leaflets 3, the blades cuneate-obovate, cuneate or oblanceo- 



late, 8-16 mm. long, sharply toothed near the apex: calyx 4-8 mm. long; lobes nearly 



subulate: corolla violet or blue; standard oblong to cuneate, 8-10.5 mm. long: pods 



3^ mm. broad. 



In fields and waste places, Quebec to Manitoba, Virginia and Texas. Naturalized from 

 Europe. Summer. Alfalfa. Lucerne. 



7a. TRIGONELLA'L. 



Annual or rarely perennial herbs, with erect or spreading stems. Leaves alter- 

 nate: blades pinnately 3-foliolate; leaflets broadened upward, toothed, commonly 

 sharply so. Flowers perfect, in short racemes or panicles, or clustered. Calyx short- 

 pedicelled: lobes nearly equal, narrow. Corolla yellow, blue or white: standard with 

 an obovate or cuneate sessile blade: wings oblong or ovate, longer than the rounded 

 keel. Stamens 10, diadelphous. Anthers all alike. Ovary sessile or short-stalked. 

 Style very short or subulate. Stigma oblique. Ovules several or many. Pod curved, 

 narrow, indehiscent or nearly so. — Differs from Medicago in the narrow standard 

 and the linear curved pods. 



1. Trigonella Monspelikca L. Plants finely pubescent. Stem simple or branched, 

 0.5-4 dm. long: leaflets 3, the blades cuneate to obovate, 3-11 mm. long, sharply 

 toothed above the middle: flowers clustered: calyx 2-2.5 mm. long; lobes subulate, 

 slightly shorter than the tube: corolla yellow, about J longer than the calyx; standard 

 cuneate, 3-3.5 mm. long, emarginate: pods linear, curved, 11-15 mm. long, reticulated,
