mostly 4-parted, sometimes 5-parted. Corolla rotate, 

 its lobes very short, deeply and more or less unequally 

 4-lobed or rarely 5-lobed. Stamens 2, divergent, inserted 

 on either side at the base of the upper corolla-lobe. 

 Anther-sacs confluent at the apex. Ovary 2-celled; 

 style slender; stigma capitate. Capsule more or less 

 compressed, emarginate, obcordate or 2-lobed, loculi- 

 cidally dehiscent. 



1. V. peregrina L. Annual, glabrous or somewhat glandular- 

 puberulent; stems erect or ascending, simple or branched, 1-3 dm. 

 high; leaves oblong, oval, linear or slightly spatulate, 6-20 mm. 

 long, the lowest opposite, short-petioled or sessile, broader than 

 the upper and mostly entire, each with a short-pedicelled flower in 

 its axil; flowers nearly white, about 2 mm. broad; capsule nearly 

 orbicular, obcordate, 2-3 mm. high. 



Occasional along the margins of streams and in the dry beds of 

 winter pools. April-July. 



2. V. byzantina (S. & S.) B. S. B. Annual, pubescent; stems 

 diffusely branched, spreading or ascending, 1.5-4 dm. long; leaves 

 ovate or oval, short-petioled, crenate-dentate or somewhat incised, 

 8-24 mm. long, the lowest opposite, the upper alternate, each with a 

 slender-peduncled flower in its axil; pedicels filiform, equaling or 

 exceeding the leaves; corolla 6-8 mm. broad, blue; capsule 6 mm. 

 broad, half as high, shallowly and broadly emarginate. ( V. bux- 

 baumii Tenore.)

 limb 2-lipped; the upper lip (galea) arched, elongated, 

 concave or keeled, laterally compressed, entire, enclosing 

 the 4 didynamous stamens; lower lip short, 3-lobed. 

 Anther-sacs oblong or linear, unequal, the outer one 

 attached to the filament by its middle, the inner one 

 pendulous from its apex. Style filiform; stigma entire 

 or 2-lobed. Capsule ovoid or oblong, loculicidally dehis- 

 cent, many-seeded. Seeds reticulated.
