POLYGALACEAE. 215 



1. Polygala bahamensis Blake, Coutr. Gray Herb. II. 47: 64. 1916. 



Plant annual with slender roots. Stems erect, 1-4 dm. tall, branched above, 

 and sometimes branched from near the base, the branches glabrous or nearly 

 so; leaves glabrous at maturity, the blades various, those of the lower leaves 

 narrowly obovate to oblong-obovate, those of the upper leaves oblong to linear, 

 1.5-3.5 cm. long, longer than the lower ones, obtuse or acute, all short-petioled, 

 the midrib prominent beneath; racemes loosely flowered; sepals about 1.5-2 

 mm. long, the upper one ovate, ciliate, and with gland-tipped hairs; wings 3-4 

 mm. long, the blades orbicular-flabellate, several-veined, short-clawed, greenish 

 and purple-tinged; keel about 3 mm. long or rarely larger; petals 2.5-3 mm. 

 long, the blades orbicular-obovate ; capsules oval or oval-orbicular, 3-3.5 mm. 

 long, glabrous; seed-body with spreading or reflexed-spreading hairs. 



Pine-land, borders of marshes, and roadsides, Great Bahama, New Providence, 

 Andros. Endemic. Referred by Mrs. Northrop to P. brizoides St. Hil., and by 

 Small (Fl. Miami 102) to P. coralHcola Small, of Florida. Perhaps not distinct 

 from the next following species.

 obtuse or acutish, short-petioled, the midrib and lateral veins prominent beneath

3. Polygala spathulata Griseb. Cat. PL Cub. 13. 1866. 



Plant perennial or sometimes annual, deep-green, glabrous. Stems slender, 

 usually several or many from a woody base, spreading, 0.3-2.8 dm. long; leaves 

 numerous, whorled in 4's, the blades cuneate to obovate or somewhat spatulate, 

 sometimes nearly as wide as long, 7-9 mm. long or rarely longer, abruptly 

 pointed, entire or obscurely toothed, obscurely punctate, glabrous, sessile or 

 nearly so; racemes few-flowered, rather slender, permanently short, the bracts 

 persistent, ovate, about 0.5 mm. long; pedicels about as long as the bracts, 

 deciduous; flowers spreading; sepals bright-green, the upper one ovate or oval- 

 ovate, the lower ones ovate, glandular-eiliate, all about 1 mm. long; wings fully 

 2.5 mm. long, the blade obovate or oblong-obovate, acute or acutish, whitish 

 with green veins, short-clawed; corolla about 2 mm. long, the petals broad, 

 united to above the middle, often erose; capsules oblong, fully 2 mm. long,
