Description
Species Description - Coarsely macrophyllous trees attaining 4-9 m, with gray trunks 1-2 dm dbh, except for minutely puberulent peduncles glabrous throughout, the stiffly papery lfts dark dull brown-olivaceous above, a little paler beneath, the shortly pedunculate capitula of fragrant whitish fls arising in fascicles from knots on trunk and older branches and randomly from annotinous lf-axils immediately below current foliage. Stipules lanceolate or triangular-lanceolate 2—8(—11) mm, striate only when young, soon becoming dry, firmly papery, dorsally smooth, deciduous. Lf-formula 1/1½-2½, the lfts in some plants stabilized at 3 per pinna, in others either 3 or 5; petioles stout 2-7.5 x 1.8-3.5 mm, charged at top with a sessile, buttonlike, plane or small-pored nectary (1.4-) 1.6-2.8 mm diam; rachis of pinnae 4-12 cm, the 1 or the further of 2 interfoliolar segments 3.5-10 cm, the proximal posterior 1ft attached close above pinna-pulvinus; lft-pulvinules in dorsal view 4-7 mm, smooth or obscurely wrinkled; lft-blades ovate-elliptic, elliptic, or broadly lance- elliptic, from inequilaterally cuneate or cuneate-attenuate base, very shortly or obscurely acuminate, the distal pair 12-22 x 4—9 cm, (2-)2.2-3.4 times as long as wide; midrib subcentric, straight or slightly incurved, pinnately 7-11-branched on each side, the primary and the incurved-ascending secondary nerves commonly depressed on upper face and prominulous beneath, the tertiary and reticular venules faint or imperceptible above, finely raised beneath. Capitula 6-12-fld, the peduncle 2-11 mm, the receptacle 1.5-3 mm; bracts lanceolate or oblong-ovate 0.6-1.7 mm, persistent; fls sessile, the (4—)5-merous perianth glabrous, the calyx weakly 5-nerved, the corolla faintly striate; calyx deeply campanulate 2-3.2 x 1.3-1.8 mm, the teeth at most 0.4 mm, often subobsolete; corolla 6.5-8 mm, the ovate lobes 1-1.8 mm; androecium 13-20 mm, 42-50-merous, the tube 7.5-11 mm (exserted 1-3 mm), the stemonozone ±0.7 mm, the intrastaminal nectary 0.4—0.55 mm; ovary substipitate, glabrous. Pods sessile, in profile broad-linear, gently retrofalcate, when well fertilized 9-15 x 2.4-4 cm and 8-11-seeded, the toughly coriaceous or lignescent valves planobiconvex, smooth glabrous, the sutures remotely undulate only where ovules abort, the ventral one elevated as a narrow wing ±1.5-2.5 mm wide; seeds (few seen) oblong-disciform to 25 x 18 mm, uniseriate along the cavity (not imbricate), the papery testa lustrous castaneous, more or less crumpled, pleurogram 0.
Distribution and Ecology - On stream banks and in swamps adjoining mangrove, below 300 m, apparently localized in S Belize (distr. Belize and Toledo), adj. Guatemala (Petén, Alta Verapaz, Izabal), and Mexico (Chiapas, Tabasco). — Map 29. — Fl. I—III; fr. V-VI.
