 Burronnding the free dvary. Drupe with a 2-1-locular putamen : cotyledons flat. — Leaves 

 alternate, or approximate hy fairs, glabrous, quite entire ; flowers axillart/, clustered or 

 solitary. 



' 2. C ferrea, O. Unarmed; leaves oval or h.nceoh.te-ovai, TiswHij emarffinafe, or hlmit, 

 approximate by pairs ; cymes equalling the petiole, umbelliform, shortly peduncled, or sessile % 



■> calyx deeply 5 -fid: lobes spreading, pointed, nearly as long as the stamens; stigma bi- 

 lobed. — Yahl, Sgmh. 3. t. 58;— Ehamnns, V. Zizyphus emarginatns, Sw. Ceanothus 



' ferreus, DC. Scntia, Brongn. — A shrub r branchlets powdery, but soon entirely glabrous ; 

 leaves arch-nerved, variable, 20'"-] 2'" long, 12"'-6"' broad: petiole 2"'-8"' long; calyx 

 scarcely 1'" long, mreading ; filaments mnch longer than the anther, exceeding the pistil ; 

 ovary 2-locular : ^^stigma-lobes divergent, blunt. — Hab. Bahamas I, Swains. ; Jamaica I, 

 Al.; Bominicat, Finl.; S. Vincent!, Guild, 



. 3. SARCOMPHALUS, P. Br. 



Calyx free from the ovary, turbinate, at length circnmscissile, leaving its entire base beloir 

 the fruit ; lobes spreading, keeled on the inside. Petals cucuUate, long-clawed : disc filling 

 up the calyx-tube, and closely Surrounding the free ovary. " Drupe with a bilocular puta-' 

 men : cells perforated at their upper end." — A tree : branchlets thorny ; leaves alternate, 

 glabrous, quite entire ; flowers cernuous, in axillary panicles : the divisions alternate along 

 the peduncle, few-flowered, corymb^orm. 



P. Browne's genus, which is here restored, was considered by Brongniart as a doubtful 

 congener of Condalia ferrea :. it is however distinguished (though nearly allied) by its per- 

 fect flowers, which resemble those of Ceanothus, by a thicker, glandidiferous disc, by its 

 high, arboreous growth, and chiefly by the peculiar inflorescence, which recalls that of many 

 Laurinea, and is without analogy among the Rhamnete I am acquainted with. . The ripe 

 drupe, which I have not seen, seems to aSori another generic character, if the following de- 

 scription (quoted fromiMM. Ht. 1. p. 120) ia correct: — " Fruit purple, globose, J" diam. ; nut 

 surrounded by a mealy, esculent pulp, ovate, penetrated above by 2 ovate holes, which lead . 

 to the cells." — Kunth has described the anthers as being posticous, &nd Brongniart adopts 

 this structure as a difierential character from all other Rhamnax, with the exception of 

 Zia/phus havanensis ; in both plants however I find the anthers not very peculiar, the cells 

 being short, and obliquely diverging from the connective, so that they burst upwards and 

 somewhat laterally at the same time. 



3. S. laurinus, Gr. — Rhamnus sarcomphalns, L. ; Ceanothus, DC. ; Scntia, Brongn. — 

 A high tree, quite glabrous, with the exception of the puberulous peduncles and flowers ; 

 leaves ovate, or broadly oval, bluntly emarginate, arch-nerved, somewhat leathery, usually 2" 

 long, li" broad ; petiole 3"'-4"' long ; stipules minute ; panicles about half as long as the 

 leaf; calyx 1"' long : lobes equalling the petals.and stamens ; ovary bilocular : stigma' shortly 

 bilobed.^ — Hab. Jamaica !, Macf., March, common in the southern districts. 



4. COLUBRINA, Mch. 

 Calyx adnate at the base, spreading, at length circnmscissile, with the persistent base ad- 

 nate to the fruit : lobes keeled on the iuside. Petals spathulate. Ovary immersed into the 

 flat disc. Capsule tricoccous : cocci dehiscent on the inner side ; testa polished. — Shrubs or 

 trees; leaves alternate; flowers clustered, in axillary cy mules, 



4. C. ferruginosa, Brong. Arboreous; branchlets rusty-iomeniose ; leaves ovste or 

 oblong, quite entire, rusty-tomentose beneath, or glabrate with the exception of the nerves ; 

 cyraules umbelliform, peduucled, usually 2-3-nate, nearly as long as the petiole ; calyx rusty- 

 tomentose on the outside ; style %-lobed at the top ; capsule subgloboae, more than twice as 

 long as the adnate cupule. — Jaeq. Amer. Pict. t. 74; Br. Jam. t. 12. f. 1? — Rhamnus 

 colubrinus, L. Ceanothus, Xam. — A low tree ; leaves variable, blunt or pointed, subcordate, 

 or rounded at the base, eglandular, arch-nerved (while those of C. cubensis are plicate, with 

 excurrent, pinnate veins), the larger ones 6" long; calyx 2'" diam. : lobes ovate, as long as 

 the petals; capsule black, 4'" diam. — Hab. Btdbamas I, Swains.; Jamaica!, Al., March; 

 Antigua ', Nichols. ; [Cuba !].
