crest consisting of several very minute processes. Style slender, a little di- 

 lated in the middle; appendage conspicuously bearded: gland sessile. Seed 

 black ; the lobes of the caruncle scarcely one-tifth the length of the seed. 



20. P. poly ga ma (Walt.) : terminal racemes spiciform, loose, the flowers- 

 at length pendulous ; wings broadly obovate, spreading, longer than the co- 

 rolla; crest conspicuous; radical racemes with wingless flowers; capsule 

 oblong, emarginate ; lobes of the caruncle more than half as long as the very

Dry sandy fields and woods, Canada! to Florida! and Louisiana! June- 

 July — (g) Stems 5-10 inches high. Leaves an inch long, mucronate. Ter- 

 minal racemes 6-15-flowered : pedicels slender : flowers larger than in P. 

 purpurea, deep rose-color or purplish. Wings with short claws. Processes 

 of the crest laciniate. Style short, cucuUate: gland exseited : appendage 

 strongly bearded. Radical racemes leafless, prostrate, often subterranean. 



§ 5. Bac ernes loose: keel not cristate: upper half of the Jilaments un- 

 connected: style slender^ without lobes: caruncle helmet-shaped, with^ 

 out appendages. 



21. P. grandiflora (Walt.): pubescent; raceme elongated, the flowers 

 distant; pedicels recurved after floAvering; wings roundish (large) covering 

 the corolla and fruit; keel large, cucuUate, connected with the lateral petals 

 and filaments only at the base ; stem ascending ; leaves ovate-lanceolate, 

 ciliolate. — Walt. Car. p. 179. P. pubescens, Miihl. cat. p. 66 ; Nutt. gen.

Dry soils. South Carolina! to Florida and Louisiana! May-Aug. — 11 

 Root thick, tortuous. Stem about a foot high, simple or virgately branched. 

 Leaves 1-li inch long, 3-4 lines broad, tapering at each end. Raceme 12- 

 18-flowered ; the lowest flowers usually remote : pedicels 2-4 lines long. 

 The 2 inferior sepals united except at the summit. Wings one-fourth of an 

 inch in diameter, at first deep rose-color, afterwards green. Lateral petals 

 much shorter than the keel, dilated above, waved, bright rose-color : keel with 

 a mere callosity at the apex instead of a crest. Filaments monad elphous; 

 straight and unconnected above. Style a little dilated and tubular in the 

 middle ; the upper part curved, bearded on the under side below the glandu- 

 lar summit. Capsule oblong-obovate, emarginate, glabrous. Seed silky -vil- 

 lous. Caruncle about one-fifth as long as the seed, laterally compressed. — 

 This most remarkable of all the N. American Polygala?, and the only one 

 destitute of a crest, resembles P. brizoides, St. Hil. Michaux strangely 

 considered it a variety of P. Senega ; and St. Hilaire & Moquin-Tandon 

 have fallen into the same mistake, having figured the flowers and seed of 

 this species from Michaux's specimeii. 



§ 6. Flowers few, large, terminal; posterior sepal concave-cucuUate, 

 with a gland at the base on the inside: keel cristate or callous at the 

 apex. (Cham^buxus, Dill.) 



22. P. paucifolia (Willd.): rhizoma creeping and branching, throwing up 

 simple erect branches, leafy at the summit ; leaves ovate, petioled; terminal 

 flowers 2-3 ; crest fimbriate ; radical flowers wingless. — Willd. sp. 3. p. 880 ;
