FABACEAE 649 



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

 at length decumbent, 4-6 dm. long, somewhat puberuloua, 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, 8-1 Omm. 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 Floridana T. & G. Foliage hoary-pubescent. Stems prostrate, 2-10 

 dm. long or longer, the upper part often densely and retrorsely tomentose : 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 mucrpnulate, 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-purple, 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 cm. long and few flowers 

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

 panicles bearing 2-4 flowers at regular intervals above the middle of the rachis is G. Floridana longi- 

 racemosa Vail. 



6. Galactia br6vipes 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 fasciculata 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 

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

 pale lilac-purple, the standard 1.5cm. 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 can6scens (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 Texana 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 regularis (L. ) B.S.P. Foliage sparingly pubescent. Stems prostrate 

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