34. GALACTIA, P. Browne. 



Calyx 4-toothod, tlic ujtpcr one broadest. A^'cxillinn ohlonj; or ohovatc, rc- 

 flexed in flower. Stamens diadelplious. Legume more or less <onipressed, 

 2-\ alvcd, tow - many-seeded. — Prostrate or twining, rarely ereet, perennial herbs, 

 ■with ehiefly trifoliolate leaves, and mostly small purplish or white flowers ifi ax- 

 illary raeemes. Bracts alternate and deciduous. Leaflets stipellate. 



* Leaves trifoliolate, with the leaflets stalked : starts twininq or /rroslrale. 



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 

 leaves, 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, compres.scd, falcate, thickened at the sutures, sprinkled 

 with short aj)pressed hairs, C - 10-seeded. — Varies with a stouter more pubescent 

 and almost villous stem, larger ( 1^' - 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 pcdicellcd, 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, Nutt. G Macreei, 

 ^^. A. Curtis.) — Dry soil, Florida to Mississippi, and northward. July and 

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

 2-3 together. 



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

 trate and sinijile ; 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 

 short-pcdicelled flowers approximate near the summit of the stout peduncle, 

 acute in the bud ; calyx, like the straight 10-seeded compressed legume, \e\j vil- 

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

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

 long. Corolla reddish purjde, one third longer than the acute calyx-lobes. 



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

 leaflets oval or oblong, rarely acute, reticulate ; racemes simple or branched, 

 often by pairs, many-flowered, rarely longer than the leaves ; flowers large, ap- 

 proximate; legume flat, 10-seeded. — Var. microphylla • every way smaller, the 

 leaflets {^'-^' long) acute or emarginate, the few flowers almost sessile in axil-
