IS. Veronica (Tourn.) L. Speedwell. 



Chiefly herbs, with small, blue, pink, or white flowers, in 

 terminal or axillary racemes or spikes, or solitary in the axils. 

 Calyx usually four-parted, sometimes five-parted. Corolla 

 wheel-shaped, the tube short, four-lobed, rarely five-lobed, the 

 lower lobe commonly the narrowest. Stamens two, exserted, 

 divergent, the anther-sacs confluent at the apex. Capsule 

 flattened, obtuse or notched at the apex. Seeds numerous, 

 smooth or rough. 



1. Flowers in axillary racemes, their bracts small _ 2. 



1. Flowers solitary in the axils, the subtending bracts leaf-like and similar 



to the leaves, usually becoming smaller toward the top S. 



2. Calyx 4-parted '^• 



2. Calyx 5-parted, the upper point small, all the sepal points with bristles; 



leaves ovate to lanceolate, sessile; racemes compact and showy. 



V. teucrium. 



3. Plants hairv; leaves ovate to obovate; species of dry soil 4. 



3. Plants glabrous or minutely glandular; if hairy, then the leaves linear or 



linear-lanceolate; species of low ground and brook margins, or aquatic. . .5. 



4. Stem pubescent in 2 lines; leaves ovate, pointed; pedicels longer than the 



calyx V. chamaedrys. 



4. Stem hairy all over; leaves oval or obovate; pedicels shorter than the 



calyx V- officinalis. 



5. Leaves all short-petioled V. americana. 



5. Leaves sessile and clasping,. or only the upper or lowermost petioled .6. 



6. Leaves ovate-oblong or oblong-lanceolate V. anagallis-aqiiatica. 



(1. Leaves lanceolate to linear ' • 



7. Leaves linear or nearly so, three-eighths to five-eighths in. wide; pedicels 



not glandular; capsule much wider than long, strongly 2-lobed , . V. scutellata. 



7. Leaves lanceolate, broadest near the base, or the lowest elongated, lanceo- 



late, clasping, five-eighths to one in. wide; rachis and pedicels sparsely 

 pubescent with glands; capsule broad, globose, emarginate. . . . V. glandifera. 



8. Pedicels shorter than the subtending bracts 9. 



8. Pedicels longer than the subtending bracts IL 



9. Corolla white or pale blue, sometimes streaked with dark blue; leaves of 



the oblong type, glabrous or short-pubescent; calyx and bracts glabrous 

 or slightly short-pubescent 10- 



9. Corolla dark blue; leaves of the ovate type, 5-7 palmately nerved; long 

 glandular-pubescent, including the bracts and calyx; annuals. . . F. arvensis. 



10. Pedicels equalling the calyx; stem glabrous or pubescent; flowers in narrow 

 racemes, more or less peduncled, the bracts becoming abruptly smaller 

 than the uppermost foliage leaves; perennials V. serpyllifolia. 



10. Pedicels much shorter than the calyx; stem glabrous or short-pubescent; 



corolla white or very pale blue; annuals V. peregrina. 



11. Sepals not heart-shaped at maturity, prominently veined; leaves of the 



ovate or oblong type; rather short petioles; leaves crenately cut-toothed, 12. 



11. Sepals heart-shaped at maturity, without prominent veins; leaves of the 



orbicular type or very broad, 3-5 lobed or 3-5 crenate; rather long 

 petioles V- hederaefolia. 



12. Corolla not longer than the calyx V. ngrestis. 



12. Corolla lon.ger than the calyx V. tournejortii.
