AEDISIACEAE 907 



cence racemose, corymbose, cymose, or clustered on scaly spurs. Flowers regu- 

 lar, perfect or polygamo-dioicous. Calyx persistent : sepals 4-6, or rarely more. 

 Corolla flat, salverform or rotate, white, pink or yellowish : tube very short : 

 lobes spreading, reflexed or even curled back, sometimes glandular-spotted like 

 the sepals. Androecium of 4-7 stamens adnate to the base or the throat of 

 the corolla-tube or at the base of the corolla lobes. Filaments sometimes form- 

 ing a tube. Staminodia wanting. Gynoecium of 4-7 united carpels. Styles 

 united. Stigma capitate, truncate or somewhat foliaceous. Ovules immersed 

 in the fleshy placenta. Fruit a rather dry berry, sometimes leathery, globose or 

 subglobose, rarely obovoid, often tipped with the base of the style. Seed soli- 

 tary, filling the fruit-cavity, often lobed at the base. 



stamens adnate to the base of the corolla-lobes ; anthers blunt. 1. Rapanea. 



Stamens adnate to the throat of the corolla-tube ; anthers acute. 2. Icacorea. 



1. RAPANEA Aubl. 



Shrubs or small trees, with a dark gray bark. Trunks often densely branched. Leaves 

 alternate: blades leathery. Flowers small, polygamo-dioecioiis, sessile or pedicelled, mostly 

 clustered on scaly spurs. Calyx free, campanulate : sepals persistent, 4-5, or sometimes 7. 

 Corolla rotate : lobes usually 4-5, imbricated, spreading, often marked with dark lines or 

 dots. Staminodia wanting. Stamens as many as the corolla-lobes, adnate to their bases. 

 Filaments very short. Anthers introrse, lying against the corolla-lobes, usually obtuse. 

 Style somewhat elongated. Stigma capitate or foliaceous. Ovules immersed in the fleshy 

 placenta, only one maturing. Fruit a rather dry berry, pea-like. Seed solitary. 



1. Rapanea Guyanensis Aubl. A branching slirub or small tree, reaching a height 

 of 6 m. and sometimes with a trunk diameter of 16 cm., with white, rather dense wood and 

 a grayish bark, sparingly branched, the branches straight, rather naked. Leaves mostly con- 

 fined to the ends of the branchlets ; blades obovate-oblong, 4-10 cm. long, leathery, obtuse 

 or retuse, revolute, mostly shining, paler on the lower side, short-petioled : flowers sessile 

 or nearly so on short stout scaly spurs scattered along the naked branchlets : calyx cam- 

 panulate, 1 mm. high ; sepals 5-6, broadly ovate, obtuse or acutish, spotted with purple : 

 corolla rotate, whitish, 4 mm. broad, 3 times longer than the calyx ; lobes 5-6, unequal, 

 oblong, spotted and striped with purple, usually obtuse, somewhat erose and giandular- 

 ciliate : anthers rather sagittate, somewhat shorter than the lobes of the corolla : fruit sub- 

 globose, 4 mm. in diameter, bluish or black, often depressed and apicuIate,sliort-pedicelled. 

 l^Iyrsine Rapanea Eoem. & Schult. ] 



Near the coast, Florida, from the Indian River, southward through the Keys and the AVest Indies 

 to Paraguay. 



2. ICACOREA Aubl. 



Shrubs or trees, usually mucli branched. Leaves alternate : blades mostly entire, 

 punctate. Flowers perfect or polygamo-dioecious, in panicles or cymes or sometimes um- 

 bellate. Calyx free, persistent, campanulate : sepals 4-5, mostly imbricated. Corolla 

 white or pink, rotate, more or less reflexed : tube short : lobes sometimes curled, marked 

 with dark lines and dots. Stamens as many as the corolla-lobes, exserted. Filaments bent, 

 inserted at the top of the corolla-tube. Anthers introrse, erect, acute. Stigma truncate 

 or disk-like. Ovules immersed in a fleshy placenta. Fruit a rather dry berry, varying 

 from black to scarlet. Seed solitary, depressed-globose, roughened. Embryo transverse in 

 the plentiful endosperm. Marlberry. Cherry. 



1. Icacorea paniculata (Nutt. ) Sudw. A shrub or small tree, reaching a height of 

 7 m. and a diameter of 15 cm. with a hard, close-grained wood, and a light gray or nearly 

 white scaly bark : branches and branchlets numerous, rather erect, terete, the latter often 

 contorted, usually rusty. Leaf-blades usually oblanceolate, sometimes elliptic, 4-18 cm. 

 long, leathery, acute or obtuse, glabrous, slightly revolute, narrowed into short grooved 

 petioles, the nerves prominent beneath : panicles 5-12 cm. long : calyx campanulate, 2 mm. 

 high ; sepals 4-6, ovate or obovate, obtuse, marked with purple dots and lines, ciliolate, 

 the tips more or less reflexed : pedicel as long as the calyx : corolla rotate-reflexed, 1 cm. 

 broad ; lobes 5, or rarely 4-6, oblong, obtuse, marked with several purple dots and lines, 

 reflexed or curled back : fruit depressed-globose, 7-8 mm. in diameter, apiculate, papil- 

 lose, black and lustrous : seeds somewhat reniform. \^Ardisia Pickeringia T. & G.] 



On the coast, south Florida, from 26° on the west and 29° on the east coast southward through the 

 Keys and the West Indies. Also in Mexico.
