mainly obtuse and the margins beset with glandular salient teeth : raceme secund, slender 

 and loosely or few-flowered : bracts mostly shorter than the calyx ; these and the slender 

 calyx-teeth beset with slender gland-tipped teetli or lobes : sinuses of the calyx sometimes 



decidedly auriculate- appendaged : anthers as in the preceding var. or more hairy. L. 



glandulosa, A. DC. in part. — Moist grounds, S. Virginia to Florida and Alabama. These 



three forms clearly run together. 



++++++ Leaves long (2 to 5 inches) and narrow ; the upper few and sparse: lip of corolla pubes- 

 cent at base : usually a pair of glands or small glandular bractlets toward the base of the short 

 pedicel. 



L. glandulosa, Walt. Glabrous, or sometimes stem sparsely and often the calyx-tube 

 densely hirsute : stem slender, 1 to 4 feet high : leaves thick and smooth, bright green, 

 lanceolate or linear (14 to 4 lines wide), callous- or glandular-denticulate : raceme or spike 

 loosely few-many-flowered, secund, often as it were long-peduncled : bracts linear and 

 subulate, more strongly glandular-toothed : calyx-lobes subulate, half the length of the 

 tube of the corolla, bearing few or numerous salient gland-bearing teeth or lobes, or occa- 

 sionally quite entire ; the sinuses not auriculate-appendaged : tube of the light blue corolla 

 5 or 6 lines long: anthers all bearded at the tip. — Ell. Sk. i. 265; A. DC. 1. c. (excl. vars.) ; 

 Chapm. Fl. 254. L. crassiuscula, Mlchx. Fl. i. 252 ; Nutt. Gen. ii. 70. — Pine-barren swamps, 

 S. Virginia (Bailey) to Florida : fl. autumn. 



■1— -i— Flowers smaller or small : tube of the corolla not exceeding 2 or 3 lines in length. 

 ++ Stem scape-like and mostly simple, hollow: leaves all or mainly in a rosulate cluster at the 

 base, fleshy: bracts of the raceme shorter than the pedicels: lobes of the calyx subulate and 

 entire, the "sinuses naked or nearly so: ribrous-rooted and mostly aquatic veryglabrous peren- 

 nials, with pale blue or whitish flowers half an inch long. 



L. paludosa, Nutt. A foot or two or even 4 feet high : stem in the larger plants some- 

 times branching above and bearing several few-many-flowered racemes : leaves flat, from 

 linear-spatulate to oblong, repand-denticulate or entire (1 to 9 inches long), sometimes 

 scattered along the lower part of the stem : corolla pubescent at the base of the lip inside. 

 — A. DC. 1. c. 376. — In water (but foliage emerged), Delaware to Florida and Louisiana. 



L. Dortmanna, L. Scape a span to a foot high, naked except a few fleshy bracts : 

 leaves in a radical tuft, linear, fleshy, terete, hollow and with a longitudinal partition : 

 raceme loosely few-flowered : lower lip of the corolla almost naked. — Fl. Dan. t. 39. — Bor- 

 ders of ponds, often immersed, New England to Pcnn., and to subarctic Amor. (Eu.) 



++ «■ Stem leafy, mostly simple, strict, and continued into a more or less pedunculate and elongated 

 virgate and naked spike-like raceme : leaves from lanceolate to obovate, barely denticulate or 

 repand: lip prominently 2-tuberculate within at base. 



= Flowers or at least the capsules horizontal, secund, scattered in the slender raceme, large for the 

 section, the tube of the corolla 3£ to 2 lines long. 



L. Ludoviciana, Gray. Glabrous, 2 or 3 feet high (from a perennial "> root), slender : 

 leaves lanceolate, acute, or the lowest spatulate and obtuse, merely denticulate, thickish, 

 an inch or two long (not over 4 lines broad), all with tapering base and the lower petioled : 

 raceme loosely 5-20-flowered : flowers commonly puberulent : corolla half an inch long : 

 calyx with nearly ■ hemispherical tube ; its lobes ovate-lanceolate, or rather cordate-lan- 

 ceolate, being rounded auriculate at the sinuses (their margins entire or obscurely few- 

 denticulate), only half the length of the tube of the corolla, and hardly longer than 

 the capsule : larger anthers densely hirsute at and near the summit, but with no bearded 

 tuft. — Proc. Am. Acad. xii. 60. — Wet prairies, W. Louisiana, Hale. Texas near Houston, 

 Lindheimer. Tube of the corolla fully a quarter of an inch long : barely a trace of pu- 

 bescence on the base of the lip. The five short auricles at the sinuses of the calyx broad 

 and entire. Intermediate, as it were, between L. -paludosa and the following. 



L. appendiculata, A. DC. Nearly glabrous, or the strong angles of the slender stem 

 above scabrous, a foot or two high from an apparently annual or biennial root, not rarely 

 branching : leaves thin, mostly denticulate or repand, an inch or two long, obtuse, the 

 lowest obovate, the others oval or oblong and mainly sessile by a broad base : spike-like 

 raceme very slender, several-many-flowered : corolla a third of an inch long : calyx with 

 turbinate tube ; its lobes linear-acuminate from a broader base, minutely hispid-ciliate, 

 equalling the tube of the corolla, their bases sagittately extended into the deflexed auricles, 

 which are sometimes subulate and all 10 distinct, but more commonly united partially or 

 wholly into 5 lobes which not rarely cover the tube : base of capsule hemispherical, much
