long.—Shady and moist ground, extending from the Gulf States into southern Texas. 
In eastern Texas is var. ATTENUATA Gray, a form with the involucral valves nar- 
rower, spatulate or oblong and cuspidate-acuminate, and attenuate-acuminate 
leaves on long petioles. 
VERBENACER. (VERVAIN FAMILY.) 
Herbs or shrubs, with opposite leaves, more or less 2-lipped or irreg- 
ular corolla, didynamous stamens, the 2 to 4-celled fruit dry or dru- 
paceous and usually splitting when ripe into as many 1-seeded indehis- 
cent nutlets.—Differs from Labiate in the ovary not being 4-lobed, the 
style therefore terminal. 
* Ovules erect: inflorescence centripetal and simple. 
+ Flowers spicate or capitate. 
+ Calyx narrow, tubular, mostly inclosing the dry fruit: corolla salverform, with 
5-lobed limb: achene-like nutlets 1-celled, 1-seeded. 
1. Bouchea. Stigma 2-lobed, one lobe abortive, the other subclavate-stigmatose : 
fruit separating into 2 nutlets. 
2. Verbena. Stigma mostly 2-lobed, anterior lobe larger, posterior smooth and 
sterile: fruit separating into 4 nutlets. 
a+++ Calyx small and short: cells of nutlets 2, 1-seeded. 
3. Lippia. Calyx 2 to 4-cleft or toothed, inclosing the dry fruit, which separates 
into 2 nutlets: limb of corolla oblique or bilabiate, 4-lobed. 
4, Lantana, Calyx very small, truncate or sinuate-toothed: limb of corolla not 
bilabiate, obscurely irregular, 4 or 5-parted: fruit drupaceous, merely girt at base 
by the calyx, fleshy or juicy. 
++ Flowers in open racemes: corolla salverform: drupe juicy: shrubs or trees. 
5. Citharexylum. Calyx in fruit girting the base of the drupe: stigmas 2: nut- 
lets 2. 
6. Duranta. Calyx in fruit ampliate and inclosing the drupe: stigma unequally 
4-lobed: nutlets 4, 
** Ovules laterally affixed: inflorescence centrifugal, cymose. 
7. Callicarpa. Flowers 4-merous, nearly regular: stamens 4, exserted: baccate 
drupe (containing 4 nutlets) subtended at base by calyx: cymes axillary. 
1. BOUCHEA Cham. 
More or less suffrutescent plants, with leaves (in ours) sessile or 
nearly so and entire, lax spikes of purple or white flowers, narrow tubu- 
lar 5-angled 5-toothed calyx mostly inclosing the dry fruit, salverform 
corolla with 5-lobed limb, 4 perfect stamens with ovate anthers and 
parallel cells, 2-lobed stigma with one lobe abortive and the other sub- 
clavate-stigmatose, and fruit separating into 2 seed-like nutlets. 
1. B. spatulata Torr. Suffrutescent, puberulent: branches terete, very leafy: 
leaves obovate, obtuse, mucronate, 18 mm. long; upper ones passing into similar 
leafy bracts; uppermost lanceolate, about equaling the calyx.—Southwestern Texas, 
cations and hills of the Rio Grande. 
2. B. linifolia Gray. Fastigiately branched from a perennial or suffrutescent 
base, glabrous: branches rigid, striate-angled and sulcate, very leafy: leaves linear. 
lanceolate, acute at both ends; uppermost passing into bracts of the loose spike; 
upper bracts subulate, much shorter than the slightly pedicellate calyx.—South- 
western Texas, dry bed or banks of the San Pedro and Rio Grande,
