284 LOBELIACE.E. (LOBELIA FAMILY.) 



8. L. spic&ta, Lam. Stem slender, strict and simple (l -3 o high) from a 

 biennial or perhaps perennial root, below and the barely denticulate leaves mi- 

 nutely pubescent ; lower and root-leaves obovate or spatulate, the upper reduced 

 to linear or club-shaped bracts ; raceme long and naked, mostly dense and many- 

 flowered ; calyx-tube short, obconical or becoming almost hemispherical. (L. 

 Claytoniana, Michx. L. pallida, Muhl.) — Moist or dry, mostly gravelly or 

 sandy soil : rather common, at least southward and westward. — A slender and 

 smaller flowered variety (beginning to blossom in June) grows in swamps at 

 Lancaster, Penn., Prof. Porter. — Corolla ordinarily 4" long. 



•w- ++ Glabrous or nearly so : leaves small, linear or lanceolate, only those from the 

 root obovate or spatulate, the uppermost reduced to setaceous bracts, all entire or 

 barely denticulate : stems very slender, simple or becoming paniculately branched 

 above : racemes loosely several-flowered. 



9. L. Nuttallii, Roem. & Sch. Stem very slender (l°-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, from Long Island, New Jersey, and the adjacent lower borders of 

 Pennsylvania, southward. 



10. L. Kalmii, L. Stem mostly low (4' -18' high) minutely angled; 

 pedicels filiform, not exceeding the linear or setaceous bracts but as long as the flower, 

 minutely 2-bracteolale or 2-glandular above the middle; calyx-tube top-shaped or obo- 

 void with an acute base, fully half the length of the lobes, in fruit rather longer 

 than they, smooth, covering the Avhole pod ; corolla bright light blue, 4"- 5" 

 long. — Wet limestone rocks and banks, Northern New England to Wisconsin 

 and northward along the St. Lawrence and Great Lakes, and through New 

 York southward to Lancaster, Penn. (Prof Porter). 



11. L. Canbyi, n. sp. Stem strict (1° -2° high), minutely angled ; pedi- 

 cels shorter than the bracts and mostly shorter than the flower, minutely roughened 

 under a lens ; bractlets none ; calyx-tube top-shaped, acute at the base, and only half 

 the length of the lobes (which, with the linear leaves, are sparsely glandular-den- 

 ticulate along the margins), in fruit becoming oblong, covering the whole pod ; 

 corolla deep blue (fully 5" long), more or less bearded in the throat. — Wet places, 

 pine barrens of New Jersey, especially at Quaker Bridge, Wm. M. Canby, C. 

 E. Smith, &c. (Also South Carolina, M. A. Curtis.) Aug., Sept. — Leaves 1', 

 rarely 1^' long, numerous, gradually diminishing in size up to the raceme, the 

 largest 2" wide. Pod nearly 3" long. 



■»- h- +- h-* Stem simple from a perennial root, and nearly leafless, except at or near 

 the base : flowers in a simple loose raceme, light blue : leaves fleshy : calyx-tube 

 acute at the base, top-shaped : auricles none. 



12. L. paludbsa, Nutt. Nearly smooth; stem slender (l°-2^° high) ; 

 leaves thickish but Jlat, scattered near the base, linear -spatulate or oblong-linear, 

 glandular-denticulate, mostly tapering into a petiole; lower lip of the corolla 

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

 coming hemispherical in fruit. — Wet bogs, Delaware (Nuttall) and southward. 

 — Corolla 5" -6" long.
