ate; calyx-teeth short, triangular; fertile legumes hairy. (A. monoica and A. 
sarmentosa, il.) — Rich soil, Florida to Mississippi, and northward. a 
and Sept. 
34. GALACTIA, P. Browne. 
Calyx 4-toothed, the upper one broadest. Vexillum oblong or obovate, 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 flowers in ax- 
illary racemes. Bracts alternate and deciduous. Leaflets stipellate. 
* Leaves trifoliolate, with the leaflets stalked : stems 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 
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, compressed, falcate, thickened at the sutures, sprinkled 
with short appressed hairs, 6 - 10-seeded. —Varies with a stouter more pubescent 
and almost villous stem, larger (13! - 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, Nutt. G. Macreei, 
M. A. Curtis.) — Dry soil, Florida to Mississippi, and northward. July and 
August. — Stem often elongated. Leaflets j' - 1/ 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, OF 
the upper ones acute; racemes single, about twice the length of the leaves, the 
short-pedicelled flowers approximate near the summit of the stout peduncle, 
acute in the bud; calyx, like the straight 10-seeded compressed legume, very vil- 
lous and hoary. (G. pilosa, Nutt.) — Dry sandy pine barrens, Florida to North 
Carolina, and westward. July and August.— Stem 29-39 long. Leaflets l' 
long. — reddish purple, one third longer than the acute calyx-lobes. 
Fh Torr. & Gray.  Hoary-pubescent; stems prosiri 
leaflets oval or oblong, rarely acute, reticulate ; racemes simple or , 
often by pairs, many-fl d, rarely longer than the leaves ; flowers large $F 
proximate; legume flat, 10-seeded. — Var. microphylla: every way smaller, the - 
leaflets (}/-4' long) acute or ma: the few fowers almost solo i ax
