 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, tlie blades often 3-nerved, narrowed into a sliort 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 Boyklnii 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 obovateor oblong-obovate 

 blades, 0.5-1 cm. long, gradually becoming narrower and longer to linear-lanceolate or 

 linear, 1-3 cm. 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 cm. long : pedicels 1 ram. 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 i-f as long as 

 the seed-body or rarely longer, sometimes overlapping. 



In calcareous soil, Georgia to Florida and Louisiana. Spring and summer. 



17. Polygala sparsifolia (Wheelock) Small. Annual, glabrous. Stems 3-6 dm. tall, 

 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 long
