0. chlargena : flowers green when dry. 



Wet pine land, Georgia, Dr. Bald^cin! Lt Conte I— ^tem 2-3 feet high, 

 leafy to the summit. Leaves scarcely an inch long ; cauline ones acute. 

 Spikes squarrose Avith the cuspidate points of the wings. Bracts twice as 

 long as the pedicels. Flowers whitish even when dry ; except in 0. which, in a 

 dried state, are of a beautiful verdigris-green, very odorous (Le Conte.) 

 Wings nearly twice as long as the corolla, with along cuspidate point. Crest 

 consisting of' 4 narrow processes, the two exterior ones simple, the others bi- 

 fid. Style nearly straight: gland scarcely pedicellate. Seeds clothed with 

 spreading hairs.— The variety ji. has the flowers more distinctly pedicellate, 

 the cyme Avith longer branches, and the processes of the crest twice bifid. 

 It may prove to be a distinct species. 



§ 3. Spikes oblong-cylindrical, compact, the fowers nearly sessile: keel 

 cristate : style 2-lobed, not cucullate in the middle : fdaments united 

 nearly to the middle : caruncle cristate, spongy. 



9. P. incarnata (Linn.) : glaucous ; Avings lanceolate, much shorter than 

 the corolla ; claAvs of the petals united into a long slender cleft tube ; lamina 

 of the lateral petals oboA^ate ; stem slender, mostly simple ; leaves hnear-sub- 

 ulate, scattered. Avithout glandular dots.— Michx: ! f. 2. p. 52; Pursh, fl.

p. stem paniculately branched; leaves very minute; tube of the corolla 

 a little longer than the Avings. — P. paniculata, herb. Le Conte.

 Georgia, Le Conte .'— Plant 1-2 feet high, erect. Leaves 4-6 lines long 

 (in /?. almost AA'anting). Spike 1-li inch long. Bracts subulate. FloAvers 

 pale purple or rose-color. Exterior sepals unequal, ovate-lanceolate. Wings 

 cuspidate, usually about half as long as the tube of the corolla. Lamina of 

 the petals distinct; the claAvs united Avith the filaments into a slender neaily 

 straight lube or sheath, Avhich is cleft on the inside : crest very conspicuous. 

 Style long and filiform the greater part of its length, curved tOAvards the sum- 

 mit, bearded at the extremity : gland sessile. Seed OA^ate, hairy. Caruncle 

 2-lobed, spongy or vesicular ;' the lobes projecting above the seed in the form 

 of a crest, and attached by the middle to the short neck or stipe of the seed. 



10. P. setacea (Michx.): Avings oblong, abruptly acuminate, two-thirds the 

 length of the petals; tube of the corolla very short; stem filifonn, simple or 

 sparingly branched ; leaves very minute, scale-like. — Michx. ! Ji. 2. p. 52 ;

North Carolina, Michaux ! Georgia ! to Florida \—H 1 ((l) DC.) Stem 

 about a foot high, often Avith one or more long, slender, erect branches. 

 Leaves scarcely more than a line long, setaceous. Spike ^ of an inch long. 

 Flowers pale rose-color. Exterior sepals unequal ; the posterior ones ovate. 

 Petals united about half their length ; lamina of the lateral ones ovate : 

 crest conspicuous, composedof 6-8 filiform, sometimes emarginate, processes.

§ 4. Spikes elongated or racemose : keel cristate : filaments united near- 

 ly to the stimmit : style dilated and cucullate in the middle: appendage,
