386 SCROPHULARIACE^:. (FIGWORT FAMILY.) 



15. SYNTHYRIS, Benth. 



Calyx 4-parted. Corolla somewhat bell-shaped, variously 2 - 4-lobed or cleft. 

 Stamens 2, inserted just below the upper sinuses, occasionally with another 

 pair from the other sinuses, exserted ; anther-cells not confluent. Style slen- 

 der ; stigma simple. Capsule flattened, rounded, obtuse or notched, 2-celled 

 (rarely 3-lobed and 3-celled), many-seeded, loculicidal; the valves cohering be- 

 low with the axis. Perennial herbs, with the simple stems beset with partly 

 clasping bract-like alternate leaves, the root-leaves rounded and petioled, 

 crenate. Flowers in a raceme or spike, bracteate. (Name from avv, together, 

 and Bvpis, a little door ; in allusion to the closed valves of the pod.) 



1. S. Hough toniana, Benth. Hairy; root-leaves ovate, heart-shaped ; 

 spike dense (5-12' long) ; corolla (greenish-white or yellowish) not longer than 

 the calyx, usually 2 - 3-parted. Oak-barrens and prairies, Mich, to Minn., 

 south to Ind., 111., and Iowa. 



16. VERONICA, L. SPEEDWELL. 



Calyx 4- (rarely 3 - 5-) parted. Corolla wheel-shaped or salver-shaped, the 

 border 4-parted (rarely 5-parted) ; the lateral lobes or the lower one commonly 

 narrower than the others. Stamens 2, one each side of the upper lobe of the 

 corolla, exserted; anther-cells confluent at the apex. Style entire; stigma 

 single. Capsule flattened, obtuse or notched at the apex, 2-celled, few - many- 

 seeded. Chiefly herbs ; leaves mostly opposite or whorled ; flowers blue, flesh- 

 color, or white. (Derivation doubtful; perhaps the flower of St. Veronica.) 



1. LEPTANDRA. Tall perennials, with mostly whorled leaves; racemes 

 terminal, dense, spiked ; bracts very small ; tube of the corolla longer than 

 its limb and much longer than the calyx ; both sometimes 5-cleft. 



1. V. Virginica, L. (CULVER'S-ROOT. CULVER'S PHYSIC.) Smooth 

 or rather downy ; stem simple, straight (2 - 6 high) ; leaves whorled in fours 

 to sevens, short-petioled, lanceolate, pointed, finely serrate ; spikes panicled ; 

 corolla small, nearly white; stamens much exserted; capsule oblong-ovate, 

 not notched, opening by 4 teeth at the apex, many-seeded. Rich woods, Vt. 

 to Minn., E. Kan., and southward. July, Aug. 



2. VERONICA proper. Corolla wheel-shaped ; capsule more or less notched, 



strongly flattened except in n. 2 and 3; low herbs. 



* Perennials, stoloniferous or rooting at base, with opposite usually serrate leaves ; 



racemes axillary, mostly opposite ; corolla pale blue. 



i- Capsule turgid, orbicular, many-seeded. 



2. V. Anagallis, L. (WATER SPEEDWELL.) Smooth, creeping and 

 rooting at base, then erect ; leaves sessile, most of them clasping by a heart-shaped 

 base, ovate-lanceolate, acute, serrate or entire (2 - 3' long) ; pedicels spreading ; 

 corolla pale blue with purple stripes ; capsule slightly notched. Brooks and 

 ditches, N. Eng. to N. J., west to the Rocky Mts. June- Aug. (Eu., Asia.) 



3. V. Americana, Schweinitz. (AMERICAN BROOKLIME.) Smooth, 

 decumbent at base, then erect (8- 15' high) ; leaves mostly petioled, ovate or 

 oblong, serrate, thickish, truncate or slightly heart-shaped at base ; the slender 

 pedicels spreading. Brooks and ditches, common. June - Aug.
