19. PORTLANDIA, P. Br. 



Calyx-limb 5-partite. Corolla infundibular: tube long, tapering towards the narrow 

 base: lobes plaited-imbricative, one lobe exterior. Stamens of Coutarea, but included. 

 Style of Exostemma. Capsule loculicide : seeds compressed, minutely foveolate, not winged. 

 — Glabrous shrubs ; leaves shortly petioled ; flowers large, single (-3) in the axils, shortly 

 peduncled. 



The peculiar aestivation of the corolla I regard as a modification of the imbricative, not 

 of the valvate type : this view is confirmed by the affinity of Portlandia with the preceding 

 genera, proved by the structure and hypogynous insertion of the stamens, and the general 

 habit. A similar observation may be made on the aestivation of Calesbaa. 



The next genus to Portlandia is the Haitian Isidorea (collected by Sir R. Schomburgk), 

 which is chiefly distinguished by a septicide capsule. 



40. P. grandiflora, I. Leaves elliptical or elliptical-oblong, pointed, leathery, shining, 

 veiny : stipules deltoid or ovate ; segments of the calyx-limb foliaceous, elliptical-lanceolate ; 

 corolla whitish, often as long as the leaves : tube gradually tapering : lobes rounded-deltoid ; 

 anthers \-\ as long as the filaments ; capsule elliptical, 5-costate. — Br. Jam. t. 11 ; Jacq. 

 Amer. Pict. t. 64.— 8'-10' high ; corolla fragrant, 8"-3" long ; anthers 14"'-6"', capsule 

 1" long. — Hab. Jamaica !, Mac/., Pd., March, common among rocks ; [S. Thomas]. 



41. P. gypsophila, Mac/. Leaves oblong, pointed, leathery, shining above, arch- 

 veined ■. secondary veins inconspicuous : stipules- subulate-roundish ; segments of the calyx- 

 limb linear-acuminate; corolla as long as the leaves: tube gradually tapering: lobes 

 rounded-deltoid ; anthers half as long as the filaments ; capsule oblong, tapering at the base, 

 smooth. — Habit of the preceding, and related to P. platantha, Hook. ; corolla 7"-8", an- 

 thers 2", capsule 2" long ; corolla-lobes 10'" diam. — Hab. Jamaica {Macf.) ; [Cuba!]. 



42. P. coccinea, Sw. Leaves ovate or elliptical-oblong, pointed, leathery, shining, 

 veiny : stipules deltoid ; segments of the oalyx-limb lanceolate, acuminate ; corolla crimson, 

 about half as long as the leaves : tube gradually tapering, cylindrical-5-costate at the base : 

 lobes deltoid ; anthers half as long as the filaments ; capsule elliptical, smooth. — 2'-3' high ; 

 leaves 5"-3", corolla 2", anthers 8'", capsule 8"'-10 w long ; corolla-lobes 4'" diam.— Hab. 

 Jamaica!, Pd., Bancr., Al., March, rare, on rocks. 



20. HILLIA, Jacq.

 tube cylindrical : lobes 6-4 (-7), imbricative. Stamens included : filaments wholly adnate : 

 anthers oblong, erect, inserted below the corolla-throat. Style filiform : stigma thickish, 

 2-lamellate. Capsule siliquiform, septicide : seeds fusiform, with a long, penicillate tail, 

 not winged. — Glabrous shrubs ; stipules foliaceous, deciduous ; flowers terminal, single,
