 softly pubescent or glabrate foliage. Leaf-blades rather leathery, elliptic, oblong or ob- 

 long-obovate, 5-15 cm. long, rounded at the apex or acuminate at both ends, undulate, 

 lustrous above, short -petioled : racemes spike-like, 5-12 cm. long, short-ped uncled : calyx 

 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. 



11. DURANTA L. 



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 repens L. A shrub or small tree reaching a height of 6m., 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. CALLICARFA 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. Vl'TBX L. 



Shrubs or trees. Leaves opposite : blades usually 3-7 digitately compound, or rarely 

 1-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 r 

 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 Agnus -Castus 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,.
