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, 
iets long.

Tobacco. Eyebright. Fig. 4038. 
Lobelia inflata L. Sp. Pl. 931. 1753. 
Annual, pubescent or hirsute, very acrid; 
stem leafy, commonly paniculately branched,

upper sessile, oval, oblong, ovate, or ovate- 
lanceolate, obtuse, or the uppermost acute; 
flowers light blue, 2-3” long, usually distant 
in somewhat spike-like racemes; lower bracts 
foliaceous, the upper subulate; pedicels 2-5” 
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-

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

sparingly repand-denticuiate, or entire, 6-12” 
long, 14’-23’ wide; upper leaves sessile, usually 
longer and narrower, linear, linear-oblong, or 
narrowly spatulate, the uppermost acute; flow- 
ers light blue, 4”-5” long, in loose racemes; 
lower bracts linear-lanceolate, the upper subu- 
late; pedicels nearly filiform, 4’-12” 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. ;
