1 Ii. cardinalis L. Cardinal Flowbe. St. simple, glabrous ; Ivs. oblong-lan- 

 ceolate, slightly toothed, acute at each end, sessile ; fls. in u terminal, bracted, 

 Beound raceme ; stam, longer than the corolla. — A tail species frequent in raea- 

 dowa and along streams. Can. to Car.W. to 111. St. 2 to 4f high, often quite glab- 

 rous as well as the whole plant. Lvs. 2 to 4' by 8 to 15 ', usually denticulate. 

 Fls. on short pedicels, few or numerous, in a superb, nodding raceme. Bracts 

 linear-subulate, raucli shorter than the flowers. Cor. deep scarlet, near 2' in 

 length. JL, Aug. f — A variety from Potsdam, N. T., has the leaves all entire. 

 Another var. from Mass. has while corollas witli more narrow segments. 



2 L. fulgens WUld. MEXio.iif Caedinal Flower. St. erect, simple, pu- 

 bescent ; lvs. pubescent, narrow-lanceolate, acuminate, subentire and revoluts at 

 edge; raceme many-flowered; stam. the length of the corolla. — Cultivated. Even 

 superior in size and splendor to No. 1. Stems 3 to 5f high, racemes 2 to 3f long.

3 L. syphilitica L. Blue Cardinal Flower. St. erect, simple ; lvs. oblong- 

 lanceolate, acute or acuminate, unequally serrate, somewhat hirsute ; rac. leafy ; 

 cal. hispidly ciliate, with the sinuses reflexed. — 1£ A showy plant, in wet mea- 

 dows and along streams, U. S. and Can., more common in the "W. States. Stem 

 erect, 2 — 4f high, simple, angular, with short haus. Lvs. lanceolate, broader at 

 base, acute at each end, somewhat erosely dentate, pilous. Fls. large, (1' long) on 

 short peduncles, each solitary in the axil of an ovate-lanceolate bract. Cor. bright 

 blue or purpUsh. Caps, half superior. July. 



4 L. glandulosa Walt. Pubescent or nearly glabrous, simple ; lvs. linear-lcmce- 

 olate, rather acute, sessile, glandular-denticulate ; fls. few, rather large ; cal. tube 

 short, hispid or pubescent, lobes lanceolate, cordate or somewhat auriculate at 

 base, mostly denticulate, half as long as the stamens, which are but half the length 

 of the corolla. — 1( In damp barrens, Va. to Fla. and La. Sts. 18' to 2f high. Lvs. 

 1 to 3' long. Fls. 9" long, blue. Pedicels 2 to 3''. Varies much in pubescence.

 oblong-linear, sessile, strongly denticulate; fls. subsessile; cal. truncate at base, 

 densely hispid, segm. ovate-aoumiuate, half the length of the coroUa, densely fim- 

 briate-toothed. — La. (Hale). A plant widely different from the foregoing. Height
