appressed-pubescent, 1.2 mm. long; aril minute, 2-lobed, about one tenth as long 

 as seed. 



In wet savannahs and low open pinelands in e. Tex., May-June; along Coastal 

 Plains from Miss, to Tex., also Mex., C.A., Cuba and S.A. 



6. Polygala sanguinea L. Fig. 507 



Slender erect annual, 4 dm. tall or less, simple or branched; leaves all alternate, 

 numerous, linear to elliptic-linear, 7-39 mm. long, 1-4.5 mm. wide, acute to 

 acuminate and mucronulate, erect or ascending, papillose-serrulate on margin 

 with subglandular teeth; peduncles 3-30 mm. long; racemes capitate to thick- 

 cylindric, very obtuse and dense, 6-14 mm. thick, the axis 7-40 mm. long; 

 bracts subulate, 1-1.5 mm. long, at length deciduous; pedicels 1.1-1.5 mm. long; 

 flowers greenish and rosy or purplish, rarely white; sepals oval to elliptic-ovate, 

 acute to subacute, glabrous, 1.3-1.8 mm. long; wings ovate-oval, 4.8-6.3 mm. 

 long, 2.5-3.5 mm. wide, rounded at apex, short-clawed, 9-nerved; keel 2.5-2.7 

 mm. long, the crest on each side of a lamella and a cuneate lobe, or these connate; 

 capsule cuneate-suborbicular, with short flattened sterile base, 2.5-3 mm. long, 

 2-2.5 mm. wide; seed subglobose-pyriform, pointed at base, rounded at apex, 

 short-pilose, 1.5-1.7 mm. long; aril 1-1.3 mm. long, the 2 lobes linear or linear- 

 oblong, scarious, appressed. P. viridescens L. 



In bogs and moist open flatwoods, wet meadows, edge of ponds and roadside 

 ditches, in n.e. Tex. and Okla. {Waterfall), May-July; from N.S. to s. Ont. and 

 Minn., s. to Tenn., Okla., La. and n.e. Tex. 



At anthesis the pedicels are 1.5 mm. long or less and the wing is more than 

 4.5 mm. long. These characteristics readily separate this species from P. mariana. 



7. Polygala mariana Mill. Fig. 507. 



Slender erect annual, 1.5-4 dm. tall, sparsely papillose-puberulent above; 

 leaves all alternate, linear or the lower spatulate, 6-24 mm. long, 0.5-2.5 mm. 

 wide, cuspidate, usually ascending; racemes capitate to short-cylindric, obtuse 

 to apiculate, 6-1 1 mm. thick, the axis 5-35 mm. long; bracts subulate-ovate, erose, 

 often ciliolate, deciduous; pedicels 1.8-2 mm. long or more; flowers pink or 

 purple; sepals elliptic to ovate-lanceolate, obtuse to subacuminate, sometimes 

 ciliolate, 0.8-1.8 mm. long; wings broadly elliptic to elliptic-obovate, 3-5 mm. 

 long, 1.3-3 mm. wide, slightly apiculate at apex, cuneate at base, commonly 

 6-nerved; keel papillose below, 2.3-3.2 mm. long, the crest on each side of a 

 lamella and a single lobe; capsule suborbicular to rhombic-suborbicular, with a 

 broad stipelike sterile base, about 2.2 mm. long, 1-2 mm. wide; seed subglobose- 

 pyriform, rostrate at base, rounded or apiculate at apex, short-pilose, 1.1 mm. 

 long; aril 0.4 mm. long, the 2 oblong cellular lobes fastened to the point of seed, 

 loosely descending and standing forward. P. Harped Small. 



In low moist open pinelands and savannahs, pitcher plant bogs, savannah-ever- 

 green shrub bogs and on seepage slopes in s.e. Tex., Apr.-Sept.; from Fla. to Tex., 

 n. to N.J., Del., Md. and Ky. 



At anthesis the pedicels are about 2 mm. long or occasionally longer and the 

 wings are rarely more than 4.5 mm. long. These characteristics readily separate 

 P. mariana from P. sanguinea. 



8. Polygala cruciata L. Fig. 508. 



Slender erect annual, 6-40 cm. tall, simple or usually cymosely branched; leaves 

 in whorls of 3 or 4 throughout or the uppermost scattered, linear to linear-elliptic, 

 the upper largest, 8-35 mm. long, 1-5 mm. wide, usually apiculate at the obtuse 

 to rounded apex, narrowed at base; peduncles to 5 cm. long; racemes thick- 

 cylindric to ovoid-cylindric, obtuse to apiculate, 1-1.7 cm. thick, the axis 6 cm.
