 shoots or stolons; stems slender, decumbent, or ascending, commonly rooting at the 

 lower nodes, 1. 5 -6 dm. high. Leaves linear or linear-lanceolate, sessile and 

 Sightly clasping, remotely denticulate, acute, 2-8 cm. long, 2-6 mm. wide;

4. Veronica officinalis L. Common Speedwell. (I. F. f. 3290.) Peren- 

 nial by stolons, pubescent; stem ascending. 0.7-2.5 dm. high. Leaves oblong, 

 oval, or obovate, petioled, 1-5 cm. long, obtuse, serrate, narrowed into the peti- 

 oles; racemes spike-like, narrow, much longer than the leaves; subulate bractlets 

 and the calyx longer than the pedicels; flowers pale blue, 4-6 mm. broad; capsule 

 obovate-cuneate, compressed, broadly emarginate, 4 mm. high; seeds flat. In dry 

 fields and woods, N. S. to Ont., S. Dak., N. Car. and Tenn. Also in Europe and

Veronica longifolia L., an erect European species with lanceolate petioled acuminate 

 sharply serrate leaves, has been found in a meadow near Appalachin, N. Y. 



5. Veronica Chamaadrys L. Germander Speedwell. (I. F. f. 3291.) 

 Perennial; stem ascending, slender, pubescent in two lines, 1-3 dm. high. Leaves

 long; pedicels filiform; flowers light blue, 6-8 mm. broad; capsule obcordate, 

 seeds numerous, flattish. In fields and waste places, N. S. and Quebec to N. Y. 

 and Penn. Nat. from Europe. May- July. 



Veronica Teucrium L., also European, similar to V. Chamaedrys, but with oblong 

 to lanceolate crenate leaves, has been found in Ohio and Conn. 



6. Veronica Wormskioldii R. & S. Alpine Speedwell. (I. F. f. 32c-" 

 as V. alpina.) Perennial; stems slender, usually simple, 5-30 cm. high. Leave* 

 Iblong, ovate, or elliptic, sessile, mostly rounded at both ends, crenulate or entire, 

 I-2.5 cm. long; flowers in a short narrow raceme, light blue, 4-6 mm. broad; pedi- 



.rter than the calyx in flower, 4-6 mm. long in fruit; capsule ellipsoid or 



obovoid, moderately compressed, emarginate, 4-6 mm. high; seeds 



numerous, flattish. Lab., mountains of Quebec and N. Eng. to Alaska, south in 



the mountains to Colo, and Nev. Apparently distinct from V. alpina L. of Europe.

 date or emarginate. alx>ut 2 mm. long, about equalling the calyx; seeds flat. In 

 fields and thickets. Lab. to Alaska. Ga., N. Mex. and Cal. Also in Europe, Asia 

 and S. Am. April-Aug.
