 long ; lobes attenuate, pubescent : corolla 10-12 mm. long, pale purple, sessile or nearly 

 so, the standard with an obovate blade : pods 4-5 cm. long, acutish, hirsute, or at matu- 

 rity glabrate, the conspicuous raised sutures glabrous : seeds 6-10, 3-4 mm. long, oblong-

 or oblong, 2.5-5 cm. long, obtuse or emarginate at both ends, rarely retuse, or the upper

 neath, or the young ones tomentose, the lateral ones usually rounded at each end, the ter- 

 minal more tapering at the base : panicles erect, solitary, 1-2 dm. long or longer : flowers 

 short-pedicelled, approximate near the top of the peduncle : calyx about 6 mm. long, 

 densely villous : corolla bright red or rose-purple ; the standard obovate, rounded above, 

 tapering to the obscurely 2-spurred base ; keel-petals paler, considerably smaller than the 

 slender wings : pods linear-oblong, 2.5-3.5 cm. long, acutish, densely tomentose : seeds 

 ovoid, acutish, brown. 



In dry sandy pine lands and swamps, North Carolina to Florida. Summer. 



14. Galactia Elliottii Nutt. Koot elongated, woody. Stems prostrate and climbing 

 on tall bushes, 1-3 m. long, angled, striate and somewhat retrorse-hirsute : leaves 

 many ; leaflets 7-9, the blades elliptic-oblong, 2-3 cm. long, obtuse or somewhat retuse, 

 mucronulate, leathery, glabrous and shining above, pubescent beneath : panicles longer
