812 Verbenaceae. 
involute in bud; anthers ovoid or oblong, with parallel cells. Ovary 
imperfectly 4-celled; cells l-ovuled; style long, bifid at the apex. 
Fruit a globose drupe with a fleshy pericarp and 4 smooth or rugose 
pyrenes. Seed oblong, exalbuminous. — Trees or shrubs, sometimes 
scandent. Leaves opposite, rarely ternately verticillate, entire or 
toothed. Cymes axillary or terminal, lax or dense. Flowers small 
or large, various in colour. 
Species about 100, concentrated in the warmer regions of the Old 
World, a few American.

— Schauer in DC, Prodrom. XI, p.656. — An erect shrub, with 
densely pubescent branchlets. Leaves 2—4-nate, shortly petioled, 
ovate, acute, entire, rounded at the base or slightly cordate, pubescent, 
especially beneath, the lower 5—8 cm long. Flowers in dense 
terminal and axillary peduncled clusters; bracts linear, as long as 
the calyx. Calyx densely pubescent, 2 cm long; tube short, cam- 
panulate; lobes lanceolate. Corolla white; tube pubescent, 2 cm 
long; lobes ovate, sub-equal, 4mm long. Stamens 1 cm long. Fruit 
globose, 8 mm in diam., covered with spongy processes so that it 
resembles a bramble. — Flow. March to April.

Calyx divided to the base into 5 distinct segments or sepals. 
Corolla-tube short and broad; limb of 4 nearly equal spreading 
lobes or the upper one rather larger. Stamens 4, inserted in the 
throat, with the anthers slightly protruding. Ovary 1-celled, with 
4 ovules collaterally suspended from a central column, which has 
4 angles between the ovules, imperfectly dividing the ovary into 
4 cells. Fruit a compressed capsule, the pericarp opening in 2 valves. 
Seed solitary, erect, without integuments (the integuments of the 
ovule not developed); embryo with 2 very large cotyledons folded 
longitudinally, a very hairy radicle, and a prominent plumule, which 
germinates before the fruit drops off. — Shrubs. Leaves opposite, 
undivided. Flowers in small cymes in the upper axils or in terminal 
panicles. 
The genus consists of very few species, widely distributed over the 
warmer maritime regions of the New and the Old World, and very nearly 
related to each other.
