cultis." According to the statement of Fries, Novit. Fl. Suec. 65. 

 1819, the Linnean agrestis is identical with his own V. versicolor, 

 being the only one of Fries' segregates common or previously known 

 in Sweden. Two specimens from Sweden seen in Herb. New York 

 Botanical Garden, one collected at Scania by N. H. Nilsson in 1881. 



Roadsides and rocky places, Newfoundland to Quebec and New 

 Brunswick; on ballast at New York City and Philadelphia; Ber- 

 muda. Introduced from central and northern Europe. 



14. Veronica polita Fries 



Veronica polita Fries, Novit. Fl. Suec. 63. 1819. "Ubique in 

 arvis Scaniae [Sweden]." In the second edition of the Novitiae we 

 are told that this is the only known station in Sweden. Well de- 

 scribed, and in the second edition contrasted with the V. agrestis 

 L. (V. versicolor Fries), both of which species of Fries were soon after 

 illustrated in Reichenbach's Kupfersammlung kritischer Gewachse, 

 plates 246 and 277 respectively. I am unable to maintain Fries' 

 contrast as to pubescence and the veining of the sepals. For further 

 discussion of this name and of the uncertain identity of the older 

 Veronica didyma Tenore, Prod. Fl. Nap. 6. 1811, of Italy, see 

 Ernst Lehmann in Bull. Herb. Boiss. II. 8: 237-244. 1908. Ten- 

 ore's mention of leaves profoundly crenate suggests polita, which is 

 the species of this group commonest in southern Italy. 



Veronica crenulata Sesse & Mocino, Fl. Mex. 5. 1892. "Habitat 

 in montibus Sancti Eremi PP. Carmelitarum [Mexico. Mocino & 

 Sesse]." Description appears to be of the species now considered, 

 which is well-established in Mexico. Not V. crenulata Hoffm., 

 1803. 



Ballast, roadsides and gardens, occasional from New York to Ohio, 

 Florida and Texas; central Mexico; Argentina. Introduced from 

 central and southern Eurasia. 



15. Veronica persica Poir. 



Veronica persica Poir., Encyc. Meth., Bot. 8: 542. 1808. "Croit 

 dans la Perse. On la cultive au Jardin des Plantes de Paris (V. v.)." 

 Apparently this is our species, but description differs from prevalent 

 forms in stating the leaves to be very obtuse and ordinarily slightly 

 longer than the pedicels and the corolla to be shorter than calyx. 

 However these states are easily reconcilable to certain stages or 

 forms, and our species is a plant well-known from Persia. Lehmann 

 doubtfully identifies persica as this species, but Lacaita (in Jour. Bot. 

 56: 55. 1918), after examination of Poiret's type, declares these 

 identical. 



Veronica precox Raf., Atl. Jour. 79. 1832. "Grown in the [Bar- 

 tram's Botanic] Garden [near Philadelphia] from seeds received 

 from a place unknown." Not V. praecox All., 1789.
