Veronica persica Poir 



Pedicels, rachis, and upper part of stem pubescent with gland-tipped hairs; 

 sepals strongly acuminate; styles 1-1.5 mm long; leaf blades lanceo- 

 late or broadly lanceolate, widest near the base, usually more strongly 



serrate 9. V. glandifera. 



Sepals obtuse to acutish; capsule obviously wider than long, plainly notched 

 at the apex; leaf blades linear-lanceolate, crenate-serrate with remote 

 teeth, all clasping 10. V. connata. 



1. Veronica peregrina L. var. typica Pennell. Purslane Speedwell. Map 

 1839. This is a common and obnoxious weed in cultivated grounds through- 

 out the state except the northern counties where it is rare. When once it 

 becomes well established in gardens, it is difficult to eradicate or to keep 

 in control. 



Maine to Minn., southw. to Fla. and Tex. ; also introduced on the Pacific 

 coast from B. C. to Oreg. ; Bermuda Islands, W. I., and w. Eu. 



la. Veronica peregrina var. xalapensis (HBK.) Pennell. Map 1840. 

 This is a variety rare to infrequent in all parts of the state except in the 

 sandy areas where it is more frequent but I have never seen it entirely 

 displace the species. 



Que. to Yukon, southw. to Ga., Calif., and Guatemala; also in S. A. 



2. Veronica serpyllifolia L. Thymeleaf Speedwell. Map 1841. 

 Infrequent to frequent throughout the state in pastures, open woodland, 

 fallow fields, and lawns. 



Nat. of Eu. and Asia ; naturalized in N. A. from Newf ., Que. to Minn., 

 southw. to Ga. and Mo., and on the Pacific coast from B. C. to n. Calif. 



3. Veronica arvensis L. Corn Speedwell. Map 1842. Frequent to 

 common in all parts of the state in pastures, open woodland, fallow fields, 

 lawns, and waste places. 



Nat. of Eurasia; Newf. to Minn., southw. to Ala. and Tex., also in Colo., 

 Utah, and on the Pacific coast from B. C. to Calif. 



4. Veronica persica Poir. Map 1843. This species has been found 

 in only four counties in the state. I first found it as a lawn weed 

 in Bluffton in 1917 and later in two other parts of Bluffton a half mile
