w- Stem leafy, often paniculately branched ; flowers loosely racemose ; sinuses 



of calyx not appendaged ; annual or biennial. 

 = Leaves chiefly linear, entire or denticulate ; pod not inflated. 



8. L. Canbyi, Gray. Stem strict (1 - 2 high), minutely angled ; pedi- 

 cels shorter than the bracts and flowers, minutely roughened under a lens ; 

 bractlets none; calyx-tube top-shaped, acute at base, only half the length of the 

 lobes (which, with the linear leaves, are sparsely glandular-denticulate), in fruit 

 becoming oblong, covering the whole pod; corolla deep blue (fully 5" long), 

 more or less bearded in the throat. Wet places, N. J., Del., and S. C. 



9. L. Kalmii, L. Stem mostly low (4 - IS' high), minutely angled; pedi- 

 cels flliform, not exceeding the linear or setaceous bracts but as long as the flower, 

 minutely 2-bracteoIate or ^-glandular above the middle; calyx-tube top-shaped or 

 obovoid, fully half the length of the lobes, in fruit rather longer than they, 

 covering the whole pod ; corolla light blue, 4 - 5" long. Wet limestone rocks 

 and banks, N. Eng. to L. Winnipeg, south to Penn., Ind., and Minn. 



10. L. Nuttallii, Roem. & Schult. Stem very slender (1-2 high), 

 terete; pedicels mostly longer than the bract and shorter than the flower, usually 

 with very minute bractlets near the base ; calyx-tube very short, depressed- 

 hemispherical in fruit, the globular pod half free; corolla pale blue, barely 3" 

 long. Sandy swamps, N. J. and Penn. to Ga. 



= = Leaves ovate or oblong, obtusely toothed ; pod inflated, wholly inferior. 



11. L. inflata, L. (INDIAN TOBACCO. ) Stems paniculately much branched 

 from an annual root, pubescent with spreading hairs (1-2 high); leaves 

 gradually diminishing into leaf-like bracts, which exceed the lower short-pedi* 

 celled flowers; calyx-tube ovoid. Dry open fields. Corolla only l-J-2" 

 long. Plant poisonous and a noted quack medicine. 



-*. *-*. -w. Stem scape-like, mostly simple, hollow ; leaves fleshy ; flbrous-rooted per- 

 ennials, very glabrous, mostly aquatic, with pale blue or whitish flowers. 



12. L. paludbsa, Nutt. Nearly smooth; stem slender (1-4 high); 

 leaves flat, scattered near the base, linear-spatulate or oblong-linear, glandular- 

 denticulate, mostly tapering into a petiole ; lower lip of corolla bearded in the 

 middle ; calyx-tube about half the length of the short lobes, hemispherical in 

 fruit. In water (but foliage emerged), Del. to Fla. and La. 



13. L. Dortmanna, L. (WATER LOBELIA.) Very smooth; scape thick- 

 ish (5 - 12' high), few-flowered ; leaves all tufted at the root, linear, terete, hollow^ 

 with a partition lengthwise ; lower lip of corolla slightly hairy ; calyx-tube 

 about as long as the lobes, in fruit much longer. Borders of ponds (often 

 immersed), N. Eng. to N. Penn., L. Superior, and northward. (Eu.)
