4. Galactia brachypoda T. & G. Foliage nearly glabrous. Stems slender, erect or 

 at length decumbent, 4-6 dm. long, somewhat puberulous, or nearly glabrous : leaves 3- 

 foliolate ; leaflets 3, the blades oblong or linear -oblong, 2-3.5 mm. long, thinnish, obtuse or 

 emarginate, glabrous or minutely appressed-hirsute above, paler, somewhat strigose or 

 glabrate beneath : calyx sessile or very short-pedicelled, 5 mm. long, clothed with spread- 

 ing yellowish hairs, the lower lobes acutish, the middle one somewhat the longest: 

 corolla purple or rose-purple, 8-10 mm. long, the standard 7-8 mm. long, its blade round- 

 ovate, apparently not retuse at the apex, paler than the other petals. 



In dry pine lands, Florida. Summer. 



5. Galactia Florid^na T. & G. Foliage hoary-pubescent. Stems prostrate, 2-10 

 dm. long or longer, the upper part often densely and retrorsely toraentose : leaves com- 

 monly longer than the internodes, the basal 1-foliolate : leaflets mainly 3, the blades 

 oval or oblong-oval, 1.5-4.5 cm. long, obtuse, rarely acutish, usually mucronulate, leathery, 

 reticulated and paler beneath : calyx 7-8 mm. long ; lobes scarious-margined, long-acumi- 

 nate, the middle lower one considerably longer than the rest : corolla rose-purjjle, 1.2-1.5 

 cm. long, the standard with an obovate blade rounded above, acute at the base : pods 

 linear, 4-5 cm. long, 4-5 mm. wide, acuminate, tomentose. 



In sand, Florida. Summer.— A small form with the petioles less than 1 em. long and few flowers 

 in nearly sessile clusters, is G. Floridana microphylla Vail ; while a larger form with more elongated 

 panicles "bearing 2-1 flowers at regular intervals above the middle of the rachis is G. Floridana longi- 

 racemosa Vail. 



6. Galactia br^vipes Small. Somewhat resembling G. Floridana. Stems spread- 

 ing, 6-15 dm. long, closely pubescent and somewhat clammy : leaves numerous, longer 

 than the internodes : leaflets normally 3, the blades mainly oval, 2-4 cm. long, deep green 

 and finely reticulated above, paler and finely appressed-pubescent beneath, the terminal 

 one as well as those of the lateral pair sessile or nearly so : petioles 1-1.5 cm. long, more 

 densely pubescent than the stem : panicles solitary at the nodes, much longer than the 

 leaves, the flowers or flower-clusters not approximate : calyx 6-7 mm. long, strigillose ; 

 lobes acuminate : corolla lilac ; standard fully 1 cm. long, the blade obovate : pods linear. 



In dry sand, near Trader's Hill, Georgia. Summer. 



7. Galactia fasciculkta Vail. Foliage pubescent. Stems prostrate or climbing high 

 on bushes, 1-2 m. long, clothed with a close fine retrorse-canescent tomentum : leaves 

 shorter than the internodes : leaflets 3, the blades suborbicular or oblong-orbicular, 1.5-3 

 cm. long, retuse, finely appressed silky-pubescent above, appressed silky-villous and paler 

 beneath : panicles several, fascicled in the axils of the leaves, forming conspicuous clusters 

 at the slightly enlarged nodes : pedicels mostly 2 together : calyx 8 mm. long, clothed 

 Avith short white silky hairs ; lobes acuminate, the middle lower one the longest : corolla 

 pale lilac-purple, the standard 1.5 cm. long, with an oblong-obovate blade, tapering to the 

 base of the claw, obtuse or acutish at the apex. 



In sand, Tampa, Florida. Spring to fall. 



8. Galactia can^scens (Scheele) Benth. Foliage pubescent. Stems several from a 

 slender woody root, branched at the base, the branches prostrate, creeping on the ground, 

 canescent throughout, many of the flowers becoming subterranean and bearing short 

 1-seeded pods : leaflets 3, the blades broadly ovate or oval, 2-4 cm. long, retuse, leathery, 

 slightly hirsute above, silky canescent-pubescent, much paler and the veins prominently 

 reticulated beneath : peduncles slender, elongated, few-flowered : calyx silky-hirsute ; lobes 

 acuminate : corolla rose-purple, the standard with an obovate blade : subterranean pods 

 8-10 mm. long and nearly as broad, reticulated, appressed-hirsute, the seeds 6 mm. long, 

 4 mm. wide, ovoid-elliptic, slightly rounded at the ends, light brown : other pods linear- 

 oblong, 2-3 cm. long, 6-7 mm. wide, acute, tapering to the base, densely pubescent, some- 

 times tomentose, the seeds elliptic-oblong. 



In sandy soil, Texas. Spring to fall. 



9. Galactia Texkna A. Gray. Foliage pubescent. Stems slender, procumbent, elon- 

 gated, conspicuously twining, retrorse-pubescent or hirsute : stipules minute, caducous ; 

 leaflets 3, the blades oval, 2.5-5 cm. long, retuse, mucronulate, minutely appressed cine- 

 reous-puberulous or glabrate above, sericeous or sparingly villous beneath, thin, becoming 

 slightly leathery : panicles few -flowered, much shorter than the leaves, often much 

 reduced : calyx 5 mm. long ; lobes attenuate : pods slightly falcate, 4-5 cm. long, acute 

 at each end, appressed-hirsute : seeds elliptic, 5-7.5 mm. long, truncate at the ends, light 

 brown. 



On plains or prairies, western Texas. Spring to fall. 



10. Galactia regul^ris (L. ) B.S.P. Foliage sparingly pubescent. Stems prostrate 

 and climbing on bushes, 4-10 dm. long or longer, minutely retrorse-pubescent, becoming
