Dry pinelands, n. Fla. and the upper pen. (Core*.) 



11. S. Beyrichii Kunth. Leaf-blades ovate, broadly oblong, suborbicular, or 

 pandurate, 2-12 cm. long, cuspidate or mucronate at the apex, or retuse, entire, 

 more or less auricled or dilated at the base: pedicels 4-8 mm. long: sepals and 

 petals of the staminate flowers 4-5 mm. long: berries subglobose, 46 mm. long. 



Woods, thickets, and hammocks, nearly throughout Fla. (Cont., W. I.) 



12. S. havanensis Jacq. Leaf-blades oblong to orbicular-ovate, 2.5-5 cm. 

 long, spiny-toothed: pedicels 1-2 mm. long: sepals and petals of the staminate 

 flowers 1-2 mm. long: berries oval or ovoid, 4-6 mm. long, black.

SUBCLASS 2. DICOTYLEDONES. 



Stems exogenous, consisting of pith, wood, and bark (endog- 

 enous in rare eases) : pith of parenchymatous cells: wood in one or 

 several layers surrounding the pith, traversed by medullary rays: 

 bark covering the wood. Leaves various : blades mostly pinnately 

 or palmately veined, their bases, or the bases of the petioles articu- 

 lated. Perianth and essential parts of the flower rarely in threes 

 or sixes. Embryo with two cotyledons. The first leaves (coty- 

 ledons) are opposite. 



Series 1. CHORIPETALAE. 



Petals separate and distinct from each other, or wanting. The 

 series embraces most of the families formerly included in the 

 APETALAE and the POLYPETALAE. 



Order LEITNERIALES. 



Shrubs or trees, with exceedingly light wood. Leaves alternate. 

 Flowers dioecious, in aments appearing before the leaves, the staminate 

 flowers borne on the base of each bract: perianth wanting: androecium of 

 3-12 stamens : pistillate flowers each with a minute perianth : gynoecium a 

 single carpel, the stigma introrse. Ovule solitary. Fruit a collection of 

 drupes each subtended by a bract. 



FAMILY 1. LEITNEKJACEAE. CORKWOOD FAMILY. 



Bark smooth, brown. Leaf -blades entire. Stipules wanting. Aments 

 from the axils of last year's leaves. Staminate aments many-flowered: 

 filaments short : anthers 2-celled. Pistillate aments few-many-flowered : 

 ovary sessile: stigma elongate. Drupes elongate. 



1. LEITNEEIA Chapm. Leaves scattered: blades shining above, petioled. 

 Staminate aments conspicuously bracted: filaments distinct. Pistillate aments 

 inconspicuously bracted: ovary shorter than the stigma. Drupes glabrous, 

 the flesh leathery. 



1. L. floridana Chapm. Shrub, or tree becoming 7 m. tall: leaf -blades nar- 

 rowly elliptic, oblong, or elliptic-lanceolate, or rarely oval, 10-20 cm. long,
