MALVACB^. 71 



Sect. 2. VACVKEno.—Fruii-iearingi calyx-tuhe baccate, not glandular. Central perisperm 

 channelled by a thick longitudinal projection of the pericarp (exhibiting consequently in 

 the transverse section a semilunar figure). 



9. P. iuermis, Jacq. Unarmed ; leaves elliptical or elliptical-oblong, pointed or blunt- 

 ish, petioled ; cymes stalked, minutely pubescent, most of them terminal ; flowers glomerate, 

 subsessile; male calyx infundibular, tapering at the base : Kmb shortly 5-lobed ; female calyx 

 at length baccate, multistriate or smooth, ovate-lanceolate, glabrous : ribs filiform. — Seem. 

 Sot. Eer. t. 34.— P. mitis, Bnt. Mus. ! S. nigricans, Chois. {nan Sw.) : a larger-leayed form. 

 P. coccinea-, Sw.!: a form identical with P. Pacurero, Kth. (figured by Seemann), with the 

 leaves smaller, more tapering, and turning black or remaining green when di-ied. The com- 

 parison of a greater number of specimens convinces me of the niecessity of combining the 

 two species, distinguished by Clioisy as P.. nigricans and P. Pacurero.— A. shrub or low 

 tree, 12'-20' bigh .- leaves very variable, pointed or bluntish at both ends, glabrous, membra- 

 naceous or leatheiy ; cymes terminal on yoimg branchlets : " peduncles at length tm-ning 

 red " (Jacq.) ; flowers yellowish-green, 2'" long ; fruit-bearing calyx 5"'-6"' long, first cylin- 

 drical, afterwards li"'-2"' thick at or below the middle, without prominent angles, "red" 

 or " black." — Hab. Jamaica I, Macf., Pd., At., Wils., March; Antigua I, PontUeu, Nichols.; 

 Dominica !, Imr. (both foi-ms) ; S. 'Vincent I, Guild., Barbadoes I, Trinidad !, Lockh., Holt., 

 Pd. ; [Cuba ! and Mexico to Ecuador !, Guiana I and Brazil]. 

 /" 10. P. obtnsata, Sw. ! Unarmed j leaves obovate or obovute-oblong, rounded at the 

 top, and tapering towards the petiole, glabrous or glabrescent ; cymes stalked, minutely pu- 

 bescent, terminal : flowers shortly pedicellate ; male calyx infimdibular : limb obtusely 5- 

 toothed ; female calyx at length baccate, elliptical-oblong, W-costate, glabrous ; ribs pro- 

 minent, obtuse. — Jacq. St. Schoenbr. 3. t. 314. — A shrub ; leaves leathery, somewhat shining, 

 turning brown by being dried; male flowers 2"'-3"' long; fruit-bearing calyx black, 4'" long, 

 2'" thick.— Hab. Jamaica!, At., March; [Cuba I, S. Barthelemi, Brazil]. 



4. NEEA, R. P. 



Calyx 5-toothed. Stamens 6-8 (5—10), included. Stigma simple, pointed. Pericarp 

 included within the baccate calyx-tube. Fmbryo oonvolutive. — ^Trees or shrubs : habit of 

 Visoma. 



The peculiarity of this genus, which had hitherto been confined to the southern continent, 

 relies not only, as Choisy supposed, on the included stamens, but on the simple style, and 

 the more involute cotyledons-: in the baccate species of Pisonia the cotyledons approach 

 this structure. 



11. JS. jamaicensis, Gr. (n. sp.). Glabrous; leaves oblong or elliptical-oblong, pointed ; 

 cymes terminal, divaricated, compound ; flowers pedicellate ; calyx broad-campanulate, with 

 blunt, erect teeth; fruit-bearing calyx-tube ellipsoidal, delicately costate. — A tree; leaves 5"-8" 

 long, 2"-2i" broad, rounded at the base, archnerved, with the primary veins distant, mostly 

 opposite : petiole 4"'-6"' long ; cyme stalked (about 3" diam.), trichotomous in the primary, 

 usually alternate in the subsequent divisions : pedicels 1'" long, pubescent with a, miaute, 

 rufous down ; involucre formed of 3-2 minnte bracts ; calyx 2"'-3"' long, 2'" broad at the 

 rounded base, not constricted at tie mouth (while in the allied N. spectabilis, Chois. Berlin 

 Abh. 1832, t. 3, it is constricted) : teeth originally i'" long, but at length sometimes sepa- 

 rated by rupture to the middle of the tube ; stamens unequal, 8, the longest equalling the 

 included style ;, style linear, acute ; fruit-bearing calyx-tube 5"'-6"' long, 2"'-3"' broad, 

 crowned by the erect teeth : longitudinal ribs filiform, about 10 stronger ; cotyledons oonvo- 

 lutive around the reduced central perisperm. — Hab. Jamaica!, discovered by J)r. Alexander 

 near Brownstown. 



XXV. MALVACE^. . 



Calyx mostly valvate. Stamens mouadelphous, indefinite (-10) by division, the primor- 

 dials being 5, opposite to the petals and connate with thejr claws : anthers unilocular, with 

 the pollen hispid. Pistil syncarpous. Embryo curved : .endosperm thin..— Leaves alternate, 

 palmatinerved, stipulate .- down usually stellate. .,
