campanulate, 3 mm. long, pubescent, undulately lobed : corolla white, glabrous without ; 
tube pubescent within, surpassing the calyx ; limb 5-7 mm. broad ; lobes rounded, spread- 
ing: fruit subglobose, about 1 cm. in diameter, reddish brown, lustrous, 
In sandy soil, Florida. Also in tropical America.

Shrubs or small trees, with sometimes armed branches. Leaves opposite or whorled : 
blades entire or often toothed. Flowers small, in elongated terminal or short axillary 
racemes. Calyx pedicelled : tube campanulate or tubular, truncate or minutely 5-lobed. 
Corolla funnelform or salverform : tube cylindric, straight or incurved : limb spreading, ob- 
lique or of 5 equal lobes. Stamens 4, didynamous, included. Anthers with unappendaged 
connectives : sacs distinct. Ovary partially or imperfectly 8-celled. Stigma oblique, some- 
times unequally 4-lobed. Ovules solitary or 2 in each cavity. Drupe included in the calyx, 
of 4 nutlets. Seeds without endosperm. 
1. Duranta répens L. A shrub or small tree reaching a height of 6 m., with gla- 
brate or finely pubescent foliage and unarmed or spiny branches. Leaves numerous ; 
blades ovate-elliptic, oval or obovate, 1.5-5 cm. long, obtuse or apiculate, entire or serrate 
above the middle, short-petioled : racemes 5-15 cm. long, recurving, paniculate : pedicels 
1-5 mm. long: calyx 3-4 mm. long, angled ; lobes acute, shorter than the tube: corolla 
lilac ; tube surpassing the calyx ; limb 7-9 mm. broad : fruit yellow, globular, 7-11 mm. 
in diameter, enclosed by accrescent yellowish calyx which is produced into a curved beak. 
In sandy soil, Florida. Also in tropical America. 
12. CALLICARPA L. 
Shrubs or trees, with usually pubescent foliage. Leaves opposite : blades entire, toothed 
or rarely lobed. Flowers in axillary sessile or peduncled cymes. Calyx unchanged at 
maturity : tube campanulate, truncate, or with 4 short lobes. Corolla white, blue or pur- 
ple: tube very short, straight: limb spreading, with 4 equal imbricate lobes. Stamens 
4, equal, often exserted : anthers with parallel sacs. Ovary imperfectly 2-celled. Stigma 
2-lobed. Ovules 2 in each cavity, laterally attached. Drupe globose or depressed, seated 
in the calyx, pulpy, white, purple, violet or red. 
1. Callicarpa Americana L. A bushy shrub 1-2 m. tall, with scurfy-stellate pubes- 
cence. Leaf-blades thinnish, ovate, elliptic or oval, acute or acuminate at both ends, ser- 
rate, glabrate above ; petioles 1-2 cm. long: cymes axillary, many-flowered, shorter than 
subtending petioles: calyx campanulate, 1-1.5 mm. long, with 5 low lobes: corolla bluish 
or pink; limb about 5 mm. broad, the lobes rounded : fruit violet, subglobose, 4-5 mm. 
in diameter. 
In dry sandy soil, Virginia and Arkansas, south to Florida and Texas. Spring and summer. 
13. VITEX L. 
Shrubs or trees. Leaves opposite: blades usually 3-7 digitately compound, or rarely 
I-foliolate. Flowers in cymes, which are sometimes whorled. Calyx campanulate or rarely 
tubular-funnelform, with 5 or rarely 3 lobes. Corolla white, yellow, blue or purplish : 
tube variable in length, straight or nearly so: limb spreading, oblique, somewhat 2-lipped. 
Stamens 4, didynamous, often exserted. Anthers with distinct nearly parallel, arched or 
spreading sacs. Ovary at first imperfectly 2-celled, becoming 4-celled. Ovules 4, solitary 
in each cavity. Drupe seated in the calyx or rarely nearly included, usually rather dry. 
Seeds without endosperm. 
1. Vitex Ágnus-Cástus L. A branching shrub 1-3 m. tall, with finely pale pubes- 
cent foliage. Leaf-blades 7-foliolate ; petioles shorter than the longer leaflets, often 
spreading ; leaflets linear to linear-elliptic, 2-10 cm. long, acutish, entire, glabrate above, 
slender-petioluled : panicles narrow, 5-15 cm. long ; clusters interrupted : calyx campanu- 
late, 2-2.5 mm. long, white ; lobes triangular, shorter than tube: corolla blue or purplish,
