herbs, with the leaves mostly opposite or whorled ; the flowers blue, flesh-cofor, 

 or white. (Name of doubtful derivation ; perhaps the flower of St. Veronica.) 



1. Tatt perennials, with mostly whorled leaves: racemes terminal, det\se, spiked: 

 bracts very small: tube of the corolla longer than its limb and much knof.r than the 

 calyx. (Leptandra, Nutt.) 



1. V. Virgiuica, L. (CULVER'S-ROOT. CULVER'S PHYSIC.) Smooth 

 or rather downy; stem simple, straight (2 -6 high) ; leaves whorled in fours 

 to sevens, short-petioled, lanceolate, pointed, finely serrate; spikes panicled; 

 stamens much exserted. Kich woods, Vermont to Wisconsin, and southward 

 often cultivated. July. Corolla small, nearly white. Pod oblong-ovate, not 

 notched, opening by 4 teeth at the apex, many-seeded. 



4 2. Perennials with opposite usually serrate leaves : flowers in axillary opposite ra- 

 cemes : corolla wheel-shaped (pale blue) : pod rounded, notched, rather many-seeded. 



2. V. Anagiillis, L. (WATER SPEEDWELL.) Smooth, creeping and 

 rooting at the base, then erect ; leaves sessile, most of them clasping by a heart-shaped 

 base, ovate-lanceolate, acute, serrate or entire (2' -3 long); pedicels spreading; 

 pod slightly notched. Brooks and ditches, especially northward; not so com- 

 mon as the next. June - Aug. Corolla pale blue with purple stripes. (Eu. ) 



3. T. Americana, Schweinitz. (AMERICAN BROOKLIME.) Smooth, 

 decumbent at the base, then erect (8' -15' high); leaves mostly petioled, ovate or 

 oblong, acutish, serrate, thickish, truncate or slightly heart-shaped at the base ; 

 the slender pedicels spreading ; pod turgid. (V. Beccab6nga, Amer. authors.) 

 Brooks and ditches; common northward. June -Aug. Flowers as in the 

 last ; the leaves shorter and broader. 



3. Perennials, with diffuse or ascending branches from a decumbent base : leaves 

 opposite: racemes axillary, from alternate axils : corolla wheel-shaped: pod strongly 

 flattened, several-seeded. 



4. T. Sdltellata, L. (MARSH SPEEDWELL.) Smooth, slender and 

 weak (6' 12' high) ; leaves sessile, linear, acute, remotely denticulate; racemes 1 or 

 2, very slender and zigzag ; floujers few and scattered, on elongated spreading or 

 reflexed pedicels ; pod very flat, much broader than long, notched at both ends. 

 Bogs ; common northward. June -Aug. (Eu.) 



5. V. officinaliS, L. (COMMON SPEEDWELL.) Pubescent; stem pros- 

 trate, rooting at the base ; leaves shm-t-petiokd, obovate-elliptical or wedge-oblong, ob- 

 tuse, serrate; racemes densely many-Jlowered ; pedicels shorter than the calyx; pod 

 obovate-triangular, broadly notched. Dry hills and open woods ; certainly in- 

 digenous in many places, especially in the Alleghanies. July. (Eu.) 



4. Leaves opposite : flowers in a terminal raceme, the lower bracts resembling tht 



stem-leaves: corolla wheel-shaped: pods flat, several-seeded. 



* Perennials (mostly turning blackish in drying). 



6. T. alpiiia, L. (ALPINE SPEEDWELL.) Stem branched from the 

 base, erect, simple (2' -6' high) ; leaves elliptical, or the lowest rounded, entire 

 or toothed, nearly sessile; raceme hairy, few-fiowered, crowded; pod obovate,
