 flowers pink : wings ovate-lanceolate, about 4 mm. long, mucronate, 6-nerved : keel with 

 a small fimbriate crest : stamens 8 : capsule orbicular or reniform-orbicular, barely 2 mm. 

 long : seeds barely 1 mm. long, sparingly pubescent, the 2 lobes of the caruncle as long as 

 the seed-body or longer. 



In grassy pine lands, Florida to Texas. Summer to fall. 



28. Polygala brevifolia Nutt. Annual, glabrous throughout. Stems 1-6 dm. long, 

 erect, or weak and deciunbent, sometimes flexuous, simple or with spreading branches, 

 4-angled : leaves in whorls of 4's except the upper ones ; blades oblanceolate, linear to 

 narrowly elliptic, 1-2.5 cm. long, punctate, acute : racemes rather dense, ovoid, mainly 7-8 

 mm. thick, often apiculate, peduncled : pedicels 1-2 mm. long, surpassing their persistent 

 bracts : flowers rose-purple : wings ovate or ovate-oblong, 3.5-4.5 mm. long, apiculate by 

 the thickened excurrent midnerve : keel with a crest of a few thick processes : stamens 8 : 

 capsule orbicular or reniform-orbicular, 2 mm. wide : seeds 1.5 mm. long, sparingly pubes- 

 cent, the 2 lobes of the caruncle about as long as the seed-body. 



In sandy swamps, Rhode Island to Florida and Mississippi. Summer and fall. 



29. Polygala cruciata L. Annual, glabrous. Stems 0.5-4 dm. tall, more or less 



branched, 4-angled : leaves in whorls of 4's or 5's ; blades spatul ate, linear-spatulate or almost 



linear, 1-3 cm. long, acute or acutish : racemes dense, 1-5 cm. long, 1-2 cm. thick, cylin- 



dric, sessile or short-peduncled : flowers rose purplish or greenish : wings deltoid, each 



tipped with a tail-like acumination, variable in size : keel with a crest of few, rather thick 



processes : stamens 8 : seeds about 1.5 mm. long, the caruncle-lobes as long as the seed-body 



or somewhat shorter. 



In bogs or moist soil, Maine to Minnesota, Florida and Louisiana. Summer.— A robust form from 

 the Gulf States, with relatively narrower leaf-blades, pedunculate racemes and more purple flowers, ie P. 

 cruciata niinosior Nash.
