 than the filiform pedicels: corolla larger, nearly half inch in diameter, blue: sepals 

 divaricate in fruit, ovate-lanceolate : capsule broadly obcordate-triangular, with a widely 

 open emargination, ripening several or rather numerous seeds. — Waste grounds, rare in 

 Atlantic States. (Nat. from Eu.) 



V. heder*:f6lia, L. Hairy : leaves roundish, often subcordate (half inch long), somewhat 



3-5-lobed, commonly shorter than the pedicels: sepals triangular-subcordate, acute, at 



length erect: corolla small: capsule turgid, 2-lobed, 4-ovuled, 2-4-seeded. — Moist banks,

V. MabilAndica, L. Spec. i. 14 (PI. Gronov. Fl. Virg.) is Polypremum procumbens. 



V. Caroliniana, Poir, Diet. viii. 520, appears to be Mitreola petiolala. 



V. rexiformis, Raf. in Med. Rep. & Jour. Bot. i. 228, is not made out: perhaps V. hede- 

 rmfolia, but its flowers are not " subsessile," nor are they said to be so in the original char- 

 acter in Med. Repository. 



V. Pti rshii, Don, Syst. iv. 573 ( V. reniformis, Pursh, Fl. i. 10), collected by Lewis and 

 Clark " on the banks of the Missouri," is not identified, although described in detail ; probably 

 not of this genus.

 perennials or biennials (of both worlds), drying blackish, scabrous; with un- 

 divided leaves, the lower opposite, and the upper gradually reduced to subulate 

 bracts of a terminal spike ; the flowers white, bluish or rose-purple, produced in 

 summer. 



B. Americana, L. Rough-hispid : stem strict, 2 feet high : lowest leaves obovate or 

 oblong, obtuse ; the others from ovate-oblong to linear-lanceolate, coarsely and sparsely 

 dentate, somewhat veiny, sessile : spike short, rather dense, or interrupted : calyx not half 

 the length of the tube of the purple (inch long) corolla : lobes of the latter euneate-ob- 

 ovate, 3 or 4 lines long. — Spec. ii. 360 ; Michx. Fl. ii. 18 ; Benth. in DC. 1. c. 498. — Moist

 tate; upper linear: spike slender, often few-flowered: tube of purple ("blue or white ") 

 corolla not twice the length of the calyx ; its rounded lobes not over 2 lines long. — Fl. 

 Ind. Occ. ii. 1061 ; Benth. 1. c. — Pine barrens, S. Carolina to Florida and Texas. (W. Ind., 

 S. Am.) 



27. SEYM3SBJA, Pursh. (Henry Seymer, an English amateur-naturalist.) 

 — Erect and mostly branching herbs (mainly of Atlantic States and Mexico, one 

 in Madagascar !) ; annuals or some perennials ; with copious and mostly opposite 

 incised or dissected leaves, the uppermost reduced to bracts of the somewhat race-

§ 1. Style filiform and long : stigma simple or slightly capitate : corolla gla- 

 brous within, except a line at the insertion of the stamens : anthers dehiscent 

 from the apex and tardily to near the base : leaves small : stems paniculately

# Leaves filiformlv dissected : corolla very deeply clef t ; the lobes oblong. 

 S. tenuifolia, Pursh. Glabrous, or the branches puberulent, very slender, 2 to 4 feet

 base: anther-cells acutish. — Fl. ii. 737 ; Benth. in DC. Prodr. x. 511. Anqnymos cassioides,
