mainly obtuse and the margins beset witli 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 teeth or lobes : sinuses of the calyx sometimes 



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



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

 three forms clearly run together. 



++++++ Leaves long (2 to 5 inclies) and narrow ; the upper few and spar.se : lip of corolla pubes- 

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

 pedicel. 



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

 densely liirsute : stem slender, 1 to 4 feet liigh ; leaves thick and smooth, bright green, 

 lanceolate or linear (li 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 lines long: anthers all bearded at the tip. — Ell. Sk. i. 205; A. DC. 1. c. (excl. vars.) •

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



-!— -1— 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, flcsliy: bracts of the raceme shorter tlian the pedicels: lobes of the cahx subulate and 

 entire, the sinuses naked or nearly so : fibrous-rooted and mostly aquatic very" glabrous peren- 

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



L. paludosa, Nutt. A foot or tw^o or even 4 feet higli : stem in the larger plants some- 

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

 linear-spatulate to oblong, repand-denticulatc 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. 370. — 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. 30. Bor- 

 ders of ponds, often inmiersed, New England to Penn., and to subarctic Amer. (Eu.) 

 ++ ++ Stem leaf}', mostly simjile, strict, and continued into a more or less pedunculate and elongated 

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

 repand : lip prominently 2-tuberculate within at base. 



= Flowers or at least the capsules horizontal, secund, scattered in the slender raceme, lar^-e for the 

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



Li. 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-flowcred : flowers commonly pubernlent : corolla half an inch long : 

 calyx with nearly hemispherical tube; its lobes ovatedanceolate, or rather cordatedan- 

 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 

 tlie 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. Literinediatc, as it were, between L. paludosa and the following. 



L. appendiciilata, 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 

 T)ranc]ung : leaves thin, mostly denticulate or repand, an incli or two long, obtuse, the 

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

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

 turlnnate 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, 

 wbicli 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
