Austin in Sullivan Co., New York in i860. It was labeled by 

 him "large form." 



6. Veronica arvensis L. 



Common in cultivated soil. From Eurasia. 



7. Veronica peregrina L. Sp. PI. 14. 1753. "Habitat in 



Europae hortis, arvisque." Described, as the specific name 

 would suggest, from specimens of an introduced plant. 

 Certainly American in origin, but it is difficult or impossible 

 to say of what portion of this hemisphere it is indigenous. An 

 abundant weed in moist cultivated soil.

 nov. 

 Veronica xalapensis H. B. K., Nov. Gen. et Sp. 2: 389. 

 1817. "Crescit in Regno Mexicano prope Xalapa 

 (alt. 630 hex.), in nemoribus Liquidambaris Styraci- 

 fluae." 

 Occasional in cultivated soil. In the western half of the conti- 

 nent this glandular-pubescent plant completely replaces true 

 peregrina. In the east it is only occasionally seen, and that 

 probably as an introduction. Intergradation to the species 

 seems to be complete. 



8. Veronica longifolia L. 



Rare in waste land. From Eurasia. 



9. Veronica Teucrium L. 



Rare in grass or waste land. From Eurasia. 

 10. Veronica Chamaedrys L. 



Occasional in grass land. From Eurasia. 

 n. Veronica officinalis L. 



Common in pasture fields and waste lands. In colonial times 

 this was grown as a medicinal plant, and very early became es- 

 tablished as if native. From Eurasia. 

 12. Veronica Americana Schwein. 



Veronica Beccabunga americana Raf., Med. Fl. 2: 109.
