On rocky bluffs and river banks, Pennsylvania to Wisconsin, Georgia and Texas. Spring and 

 summer.

 habit. Corolla pink-purple : filaments mostly united but the tube very short : anthers 

 scarcely if at all auricled at the base : capsules ovoid, less than 1 cm. long, slightly longer 

 than the sepals. 



On prairies, Maryland to Missouri, Alabama, and Arkansas. Spring and summer. 



4. Dodecatheon Stanfifeldia Small. Leaf-blades spatulate, 7-13 cm. long, entire,, 

 undulate and obtuse, the petiole-like bases relatively slender : scapes erect, 3-4 dm. tall, 

 slender, glabrous : umbels few-flowered : calyx-lobes lanceolate, 3-5 mm. long, acute : 

 corolla rose-purple, showy ; lobes obovate, mainly about 2 cm. long.

Family 3. THEOPHRASTACEAE D. Don. Jacquinia Family. 



Shrubs or small trees, with a light bark. Leaves opposite or somewhat 

 whorled : blades leathery, yellowish, varying from retuse to apieulate, persistent. 

 Flowers perfect, yellowish, in racemes, corymbs or panicles. Calyx campanu- 

 late, of 5 imbricated sepals. Corolla campanulate or rotate-salverform : lobes 

 5, imbricated in the bud, spreading, with a series of staminodia which represent 

 the outer series of stamens, attached below each sinus. Androecium of 5 stamens 

 adnate to the base of the corolla-tube. Staminodia at the sinuses of the corolla. 

 Gynoecium of 5 united carpels. Styles united, mostly hidden by the converging 

 anthers. Ovules not immersed in the placentae. Berry leathery, subglobose. 

 Seeds few or many. 



1. JACQUINIA L. 



Characters of the family, as given above. Joewood. 



1. Jacquinia Key6nsis Mez. A shrub or small tree, reaching a height of 5 m. and 

 a maximum trunk diameter of 10 cm., with a smooth blue-gray blotched bark, branched 

 above into a round top, the young branchlets angled, rusty-puberulent, sometimes orange or 

 yellowish green, becoming terete, darker and glabrous with age and marked with conspicu- 

 ous orbicular leaf-scars. Leaf-blades leathery, cuneate-spatulate or oblong-obovate, 1-5 cm. 

 long, yellowish green, 3-nerved, glabrous, shining, retuse or obtuse, often mucronulate, 

 revolute, short-petioled : racemes 2-6 cm. long : calyx campanulate, 2-3 mm. high, nar- 

 rowed to the club-shaped pedicel : sepals orbicular-ovate, obtuse : corolla straw-colored, 

 salverform, about 1 cm. broad; lobes longer than the tube, spreading, oblong, obtuse: 

 staminodia shorter than the corolla-lobes, oblong, erose at the apex : stamens shorter than 

 the staminodia: berry subglobose, 8-10 mm. in diameter. [J. armillaris Chapm., not 

 Jacq.] 



On and near the coaBt, southern peninsular Florida and the Keys. 



Family 4. AE-DISIACEAE Juss. Myrsine Family.
