 lobes ovate. 3. V. hederaefolia. 

 Pedicels shorter than the subtending bracts.

Foliage glabrous or glandular : capsules orbic- 

 ular and slightly notched. 5. V. peregrina. 

 Perennial : capsules merely retuse or truncate. 6. V. serpyllifolia. 

 Flowers in axillary racemes : bracts small. 



Foliage pubescent : species of dry soil. 7. V. offtcinalis. 



Foliage glabrous or glandular : species of low grounds 



or brooks. 



Leaf-blades broad : capsule swollen, many-seeded. 

 Stem-leaves with petioled blades : capsules 



mostly over 3 mm. long, 2-lobed. 8. V. americana. 



Stem-leaves with sessile blades : capsules mostly 



less than 3 mm. long, shallowly notched. 9. V. Anagallis-aquatica. 



Leaf-blades narrow : capsule flat, few-seeded. 10. V. scutellata. 



1. V. Tournefortii C. C. Gmel. Stems branched, 1-4 dm. long: leaf -blades

 than the bracts: calyx-lobes elliptic to lanceolate, 4-5 mm. long: corolla blue, 

 9-11 mm. wide: capsules nearly reniform, 7-8 mm. wide, many-seeded. Oc- 

 casional, in cultivated grounds. Nat. of Eu. Spr. and sum. 



2. V. agrestis L. Stems 0.5-3 dm. long: leaf -blades ovate to suborbicular or 



in fields. Nat. of Eu. Spr. FIELD-SPEEDWELL. 



3. V. hederaefolia L. Stems branched at the base, the branches reclining 

 or decumbent, often matted, sparingly pubescent: leaf -blades reniform or 

 orbicular-reniform, 0.5-1.5 cm. long, 3-5-lobed, rounded or cordate at the base, 

 rather long-petioled : pedicels as long as the leaves or slightly shorter: calyx- 

 lobes ovate, 3-4.5 mm. long, acute: corolla 3-4 mm. wide, much shorter than 

 the calyx: capsules depressed, swollen, slightly 2-lobed, 5-6 mm. broad, 2-4- 

 seeded. M. Common, in shaded banks along the Conestoga Creek. Nat. of 

 Eu. Spr. and sum. IVY-LEAVED SPEEDWELL. 



4. V. arvensis L. Stems 0.5-3 dm. long: leaf -blades ovate to oval, 5-12 mm. 

 long, crenate or incised: pedicels shorter than the bracts: calyx-lobes oblong 

 to oblong-lanceolate, 1-2.5 mm. long: corolla 1.5-2 mm. wide: capsules about 

 3 mm. wide. Common, in waste places and cultivated grounds. Nat. of Eu. 

 Sum. CORN-SPEEDWELL. 



5. V. peregrina L. Annual, 0.5-4 dm. tall: leaf -blades oblanceolate to oblong 

 or linear, 1-3 cm. long, the lower ones, at least, toothed: calyx-lobes linear or 

 slightly broadened upward: corolla 2-3 mm. wide: capsules 4 mm. wide,
