1. X. americana, L. Leaves elliptical; flowers racemose or corymbose; petals 4; 

 drupe oval or oblong.— /ffc?. Amer. Fid. t. 107 ; TStss. Fl. 3. t. 30 ; Dese. Fl. 2. t. 132.— 

 X. multiflora, Jacq. X. aculeata, Tuss. X. montana, Marf. X. inermis, I. X. sene- 

 galeusis, Rich. — A tree, usually spiny ; leaves mucronate or blunt ; petals oblong, white, 

 '■* odorous, internally villous. — Hab. Jamaica !, Mac/. ; S. Vincent !, Guild. ; [Florida ! to 

 Buenos Ayres ! ; trop. Africa ! ; East Indies]. 



2. HEISTERIA, L. 



Calyx at length much enlarged, spreading. Petals 5. Stamens 10, all fertile. Ovary 

 of Ximenia. — Trees; flowers yiwcJc/e^^, clustered, or single in the axils. 



2 H. coccinea, Jacq. Leaves oblong, acute; flowers single, pedicellate; calyx at 

 length red, obsoletely 5-lobed : lobes rounded ; petals distinct. — Ja^q. Amer. Pict. 1. 122. — 

 Calyx 1" diam. around the oblong drupe; flowers white. — Hab. Dominica!, Imr.; [Marti- 

 nique]. 



3. SCHCEPFIA, Schrei. 



Ca?y» adnate : limb truncate, obsolete. Coro/^a sympetalous, 5 (-4-6)-fid. Stamens e^i- 

 petalous, opposite to the corolla-lobes. Ovary semi-inferior, 3-celled from copious tissue : 

 ovules 3, hanging from the central placenta, fiUiug up the cavities. — Shrubs ; flowers usually 

 clustered in the axils : involucel 8-4i.Jld. 



3. S. arborescens, S. S. Leaves ovate-oblong, bluntly acuminate, rounded above the 

 contracted base ; corolla-tube campanulate : lodes thrice shorter, reflexed, ovate, dlunt, in- 

 ternal Iv pubescent; drupe ovoid (6'" long). — Codouium, V. S. americana, W. — Leaves 

 2"-3i'' long, shining. — Hab. Jamaica !, Al. ; Antigua !, Nichols., Wullschl., Montserrat, 

 Dominica CW^[^,^joix^uadj^e !^^ _ 



1 4. S. Wfeoiaii^^ffr/^.*^.). "Tilaves enTptical, pointed or bluntish, acute at the base ; 



'' corolla-tube campanulate: lobes thrice shorter, reflexed, deltoid, pointed, internally gla- 

 brous ; drupe ovoid (3'" long). — Very similar to the preceding, but distinguished by its 

 smaller fi-ait. Leaves 1 \"-%" long ; clusters equalling the petiole : pedicels fascicled, as long 

 as the glomerate (3-1) flowers ; corolla l^'" long, thrice as long as the calyx ; anthers ovoid- 

 globose, emarginate, subsessile at the throat, included, covering (as in the preceding) a 

 small tuft of bristles on the base of the lobes ; style simple, shorter than the corolla-tube ; 

 drupes (black in drying) 1 -seeded: blunt top free from the calycine covering. — Hab. Ja- 

 maica !, March; [Cuba I, in woods at Matanzas, RugeC]. 



|4. MAPPIA, Jacq. 



Calyx minute, 5(-4)-dentate, not enlarged. Petals 5 (-4), distinct, villous within. Sta- 

 mens 5 (-4), alternate with the petals, hypogyuous : filaments long. Ovary superior, sur- 

 rounded by a cupuliform disc, 1-celled: ovules 2, hanging from its summit : style short, 

 suboblique: stigma obscurely lobed.— Shrubs; flowers in axillary, peduncled, compound, 

 small, corymbiform racemes. 



The Icacinea, to which this genua belongs, may be interpreted by the adhesion of the 

 placenta to the suture of a single carpel j but, if better understood, they may perhaps prove 

 to approach Cornea. 



5. M. racemosa, Jacq. Leaves lanceolate-oblong, pointed, often porose beneath in 

 the vein-axils, exceeding the panicles ; petals oblong ; stamens included, disc 5-lobed, gla- 

 brous ; lobes rounded ; drupe ovate, pointed.— /acy. H. Schmribr. 1. 1. 47.— M. aSanis, Mrs. !: 

 the form with the leaves not porose, but both leaf-kinds occur on the same branch. Icacina

 ovoia-oolong (not bilobed).— Hab. Jamaica I, Mac/., Pd., in woods. Port Royal, S. Anns,
