 lance-linear, acute, denticulate; racemes mostly alternate; pedicels di- 

 varicate. Beck, Rot. p. 261. 

 Shield-like Veronica. Vulgo — Scull-cap Speedwell. 



Glabrous. Root perennial, creeping. Stem weak, often branched and diffuse, 

 glabrous, 8 t<> 15 inches lonr. leaves scmiamplexicaul, narrow, 1 1-2 to 3 inches 

 long, remotely denticulate, sometimes nearly entire. Racemes mostly simple, 

 Long, flaccid; pedicels filiform; bracts minute, lanceolate. Corolla purplish 

 blue, <>r flesh-colored, lobes roundish-ovate. Capsule broad, suborbicular, much 

 compressed.

Foreign Veronica. Vulgo — Purslane-leaved Speedwell. Neckweed. 



Whole plant glabrous. Root annual. S/ew often branched at base, 4 to 8 inches 

 hi, b. Leaves fleshy ; radical ones petiolate, ovale ; those of the stum sessile, spa- 

 ringly dentate ; upper ones narrower, entire. CalyxAobee resembling the small 

 upper leaves, or bracts. Corolla white, small and fugacious, with the lobes nearly 

 equal. 

 Hub. Gardens, and other cultivated grounds: common. FL May. F r . June. 



Obs. This species,— which probably lias also been introduced,— had therepu- 

 fion, some years ago* of being useful as a medicine in scrophulous affections ; and 

 hence the name "Neck-weed." See Burton'* Med. <$* Phys. Journal^ Vol. 3. pail 

 I. p. '24. Its alleged virtues, however, seem to require continuation. 



7. V. arvensis, /,. Stem erect or assurgent, pilose; lower leaves on 

 short petioles, cordate-ovate, incised-crenate ; upper leaves alternate, 

 sessile, lanceolate, nearly entire ; flowers 6ubsessile. Beck } Bot.p. 262. 

 V. agrestis. Florid. Cestr. p. 2. 



Field Veronica. Vulgo — Cora Speedwell. 



Whole plant pilose. Root annual. Stem mostly erect, 2 to 8 inches high, nft*n 

 branched at base; branches assunrent. Fl otrers on short peduncles. Ca/yar-lotx s 

 unequal. Corolla pale blue, shorter than the calyx. Capsule much compres- 

 sed, ciliate. 



Hub Dry banks, fields, and exsiccated swamps ; frequent. Fl. May. Fr. June 



Obs. This is the plant which I was prevailed on to call "V. agrestis," in my 

 Catalogue, — though I then suspected it to be the arvensis ; and am now satisfied ( f 

 the fact. It is doubtless a naturalized foreigner. 



8. V. hederifolia, L. Stem procumbent ; leaves petiolate, roundish- 

 •vate, somewhat 5-lobed ; flowers pedunculate ; lobes of the calyx cor- 

 date-ovate, acute, ciliate. Beck, Bot. p. 262. 



IVY-LEAVED VERONICA. 



Root annual. Stem 5 to 10 inches long, diffuse, pilose, the pubescence somewhat 

 in lines. Radical or primordial leaves persistent, opposite^ oval, on long petioles,
