8: style filiform, auricled near the almost sessile stigma, prolonged into a short tufted 
appendage: capsule 4 mm. long, grooved: seeds pubescent, beaked, the 2 lobes of the 
caruncle spongy, lenticular, enveloping the beak.

elongated, slender-peduncled, the rachis 2-10 cm. long, loosely-flowered : pedicels 0.5-1 
mm. long, their bracts deciduous : flowers pale-purple : wings spatulate, elliptic-obovate or 
oblong, 1-2 mm. long, the blades often 3-nerved, narrowed into a short claw, twice larger 
than the other sepals: keel crested with a few processes : stamens 8 : style minute, hooded 
at the sessile or nearly sessile stigma, prolonged into a filiform tufted appendage, or the 
tuft sometimes sessile or wanting: capsule about 1.5 mm. long: seeds very pubescent, 
the 2 lobes of the caruncle minute. 
In sandy soil, Mississippi to Texas and Mexico. Spring and summer. 
16. Polygala Boykinii Nutt. Annual or perhaps perennial. Stems branched at the 
base, the branches erect or ascending, 2-6 dm. tall, wire-like, angled, simple or sparingly 
branched : leaves in whorls of 4’s or 5’s, the lower ones with obovate or oblong-obovate 
blades, 0.5-1 cm. long, gradually becoming narrower and longer to linear-lanceolate or 
linear, 1-3 em. long at the top of the stem, acute or acutish, those on the branchlets 
alternate: racemes spike-like, 4-6 mm. thick below, narrowly conic, long-peduncled, the 
rachis 2-15 em. long: pedicels 1 mm. long, their bracts deciduous: flowers white or green- 
ish white: wings suborbicular, varying to ovate or obovate, fully 2 mm. long, obtuse, sev- 
eral times larger than the other sepals: keel crested with a few broad processes: stamens 
8: style hooded above the stalked stigma, produced above into a curved tufted appendage : 
capsule 3-4 mm. long: seeds stout, pubescent, the 2 lobes of the caruncle 3—} as long as 
the seed-body or rarely longer, sometimes overlapping. 
In calcareous soil, Georgia to Florida and Louisiana. Spring and summer. 
17. Polygala sparsifdlia (Wheelock) Small. Annual, glabrous. Stems 3-6 dm. pe 
sparingly branched or bushy, sometimes nearly naked : leaves in a few approximate whorls, 
near the base of the stem or alternate; blades linear to lanceolate, 8-10 mm. long or smaller, 
acute or sharp-tipped, sessile : racemes spike-like, 2-5 cm. long, 3-4 mm. thick, on d 
and slender peduncles, tapering: flowers pale, early deciduous, leaving a long na 2 
rachis: wings oval or orbicular-oval, about 2 mm. long: capsule oval-elliptic, baros 
mm. long: seeds slender, strigillose, with a 2-lobed caruncle about } the length of the 
seed-body. [P. Boykinii var. sparsifolia Wheelock. ]
