 stouter, puberulent or glabrous. 2-4 high. Basal 

 leaves oval or obovate, obtuse ; stem leaves spatu- 

 late, oblong, or lanceolate, obtuse, sometimes 

 slightly scabrous, denticulate or entire, or the 

 uppermost narrower and acute; spike-like raceme 

 elongated, usually dense; bracts linear, glabrous; 

 pedicels very short ; calyx-lobes linear-subulate, 

 nearly as long as the corolla-tube, the sinuses 

 with subulate deflexed auricles; flowers blue, 

 4"-5" long. 



In dry soil, Virginia to Ohio and Illinois, Georgia 

 and Kansas. June-Aug. 



11. Lobelia inflata L. Indian or Wild 

 Tobacco. Eyebright. Fig. 4038. 



Lobelia inflata L. Sp. PI. 931. 1753. 



Annual, pubescent or hirsute, very acrid; 

 stem leafy, commonly paniculately branched, 

 l-3 high. Leaves thin, repand-dentate or 

 denticulate, the lower oval or obovate, obtuse, 

 l'-2i' long, narrowed into short petioles, the 

 upper sessile, oval, oblong, ovate, or ovate- 

 lanceolate, obtuse, or the uppermost acute; 

 flowers light blue, 2"-s" long, usually distant 

 in somewhat spike-like racemes ; lower bracts 

 foliaceous, the upper subulate ; pedicels 2"-%" 

 long in fruit ; calyx glabrous or nearly so, 

 its subulate lobes about as long as the corolla ; 

 capsule inflated, 3"~4" long, finely transversely 

 veined between the ribs. 



In fields and thickets, usually in dry soil, Labra- 

 dor to Saskatchewan, Georgia, Kansas and Arkan- 

 sas. Gag-root. Puke-weed. Asthma-weed. Low- 

 belia. Emetic-weed. Bladder-pod lobelia. July-

 Lobelia. Fig. 4039. 



Lobelia Kalmii L. Sp. P!. 930. 1753. 



Perennial by short offsets, glabrous through- 

 out, or sparingly pubescent below ; stem leafy, 

 erect, paniculately branched, rarely simple, 

 slender, 6-20' high. Lower and basal leaves 

 spatulate, obtuse, narrowed into short petioles, 

 sparingly repand-denticulate, or entire, 6"-l2" 

 long, ii'-2i' wide; upper leaves sessile, usually 

 longer and narrower, linear, linear-oblong, or 

 narrowly spatulate, the uppermost acute ; flow- 

 ers light blue, 4"-S" long, in loose racemes ; 

 lower bracts linear-lanceolate, the upper subu- 

 late ; pedicels nearly filiform, 4"-i2" long, usu- 

 ally 2-glandular or 2-bracteolate near the middle; 

 calyx-lobes lanceolate-subulate, longer than the 

 turbinate tube, the sinuses not appendaged ; cap- 

 sule wholly inferior, not inflated, campanulate or 

 subglobose, about 2" long. 



On wet banks, and in wet meadows, Nova Scotia 

 to New Jersey, west to Ontario, Manitoba, Ohio,
