8. L. spic&ta, Lam. Stem slender, strict and simple (l°-3° 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. 



+-*- ++ 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 puniculately branched 

 above : racemes loosely several -flowered. 



9. Ii. iTuttallii, Rcem. & Seh. Stem very slender (l°-2° high), terete; 

 pedicels mostly longer than the bract and shorter than the flower, usually with very 

 minute bractlcts 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; 

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

 minutely 2-bracteolale or 2-glandulnr 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 whole 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 (l°-2°high), minutely angled ; pedi- 

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

 under a lens ; brackets 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 (fuAy 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- Stem simple frorri a perennial root, and nearly leafless, except at or near 

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

 acute at the base, top-shap d : auricles none. 



12. L. paluddsa, Nnt-t. Nearly smooth; stem slender (l°-2^° high) ; 

 haves thick.ish but flat, scattered near the base, linear-spatu/ate 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-
