ate; calyx-teeth short, triangular; fertile legumes hairy. (A. monoica and A 

 sarmentosa, Ell.) — Rich Boil, Florida to Mississippi, and northward. August 

 and Sept. 



34. GALACTIA, P. Browne. 



Calyx 4-tOOthed, the upper one broadest Vexillum oblong or obovatc, re- 

 flexed in flower. Stamens diadelphous. Legume more or less compressed, 

 2-valved, few -many-seeded, — Prostrate or twining, rarely erect, perennial herbs, 

 with chiefly trifoliolate leaves, and mostly small purplish or white Mowers in ax- 

 illary racemes. Bracts alternate and deciduous. Leaflets stipellate. 



* Leaves trifoliolate, rath the leaflets stalked : steins twining or prostrate. 



1. G. spiciformiS, Torr. & Gray. Stem twining, minutely pubescent; 

 leaflets (1' long) thick and rigid, oblong-oval, obtuse or emarginate at both ends, 

 smooth above, pubescent beneath ; racemes spike-like, mostly longer than the 

 haves, the nearly sessile, mostly solitary flowers scattered on the common pedun- 

 cle nearly to its base ; corolla 2 - 3 times the length of the acuminate hairy calyx- 

 lobes ; legume coriaceous, compressed, falcate, thickened at the sutures, sprinkled 

 with short appressed hairs, 6 - 10-sceded. — Varies with a stouter more pubescent 

 and almost villous stem, larger ( H' - 2'), thinner, and mostly acute leaflets, longer 

 and stouter many-flowered racemes, and nearly straight legumes. (G brevistyla, 

 Schlect.) — South Florida. Aug. and Sept. 



2. G. pilosa, Ell. Stem twining, pubescent or smoothish, much branched ; 

 leaflets thin, varying from oval to linear-oblong, obtuse, rounded or emarginate 

 at both ends, pubescent and paler beneath, often smooth above; racemes slender, 

 commonly longer than the leaves, sometimes 4-6 times as long ; flowers single 

 or 2-3 together, scattered on the common peduncle, distinctly pedicelled, acu- 

 minate in the bud ; calyx sparse-hairy or smoothish, the acuminate lobes much 

 shorter than the purple corolla ; legume nearly straight, somewhat compressed, 

 covered with short appressed hairs, 10-seeded. (G. mollis, Ntttt. G. Macrcei, 

 .1/ .1. Curtis.) — Dry soil, Florida to Mississippi, and northward. July and 

 August. — Stem often elongated. Leaflets ^'-l'long. Racemes occasionally 

 2 - 3 together. 



3. G. mollis, Michx. Villous and somewhat hoary ; stems mostly pros- 

 trate and simple ; leaflets oval or oblong, obtuse or emarginate at both ends, or 

 the upper ones acute; racemes single, about twice the length of the leaves, the 

 sliort-pedicclled flowers approximate near the summit of the stout peduncle, 

 acute in the bud ; calyx, like the Straight 10-si-cdcd Compressed legume, very vil- 

 lous and hoary. (G. pilosa, Mill.) — Dry sandy pine barrens, Florida to North 

 Carolina, and westward. July and August. — Stem 2° - 3° long. Leaflets 1' 

 long. Corolla reddish purple, one third longer than the acute calyx-lobe- 



4. G. Floridana, Torr. & Gray. Hoary-pubescent; stems prostrate; 



leaflet- oval or oblong, rarely acute, reticulate; racemes simple or branched, 

 Often by pairt, many flowered, rarely longer than the leaves ; flowers large, ap- 

 proximate, legume flat, 10-eeeded. — Var. mkrophylla; every way smaller, the 

 leaflets (£'-5' long) acute or emarginate, the few Bowers almost sessile in axil-
