Scientific Name:Tococa broadwayi Urb.
Description:Species Description - Erect shrub, up to 1.0-2.5(-3.0) m tall; stems with the trichomes arranged in 2 lines along the internodes, the trichomes 2-5 mm long, late caducous, the nodes with tufts of glandular and nonglandular trichomes up to 4-9 mm long. Leaves isophyllous, oblong-elliptic, 30-60 X 20-40 cm, apex slightly acute to obtuse, base round to obtuse, adaxial side glabrous to sparsely glandular-setose, abaxial side glabrous except for the inframarginal area covered by soft trichomes, light green, 5(-7)-plinervate, the secondary nerves diverging 3-7 cm above the base of the blade, chartaceous to coriaceous, entire to obscurely serrulate; petioles 3-20(-23) cm long, sparsely pubescent; domada absent. Inflorescence a terminal panicle of 10-40 flowers, 10-22 cm long, the axis green, terete. Flowers on pedicels 1.2-1.5 mm long; bracts persistent, elliptic, 5-9 X 1-3 mm; hypanthium campanulate, 3-4 mm long, with very sparse, minute, clavate glands, otherwise glabrous; outer calyx teeth narrowly deltoid, projecting upwards parallel to the inner teeth, but never reaching the same height, sparsely setose, 2 mm long, inner calyx teeth ovate-oblong, fused up to 0.5 mm at the base, 2.5-3.5 mm long; the ring inside the torus with minute glandular trichomes; petals 5, ovate-oblong, entire, 8-10 X 4-5 mm, smooth, glandular-setulose towards the apex, white; stamens all the same size; filaments 4.0-5.0 mm long, with small sessile glands; anthers blue; the connective with a dorsal-basal blunt tooth; thecae 4.5 mm long, opening by a upright pore; ovary 5-locular, 1/2 inferior, the superior portion sulcate, the apex truncate, with a ring elevated 0.1-0.5 mm; style with sparse minute glands at the base, 8-9 mm long; stigma capitate. Fruits globose, 4.5-5.0 mm long, black, glabrous; seeds evident through the pericarp, truncate-obovate, 0.5-0.8 mm long, without capitate trichomes in the raphal area, with sculpturing, anticlinal walls curved, periclinal walls flat, boundaries between periclinal walls flat.

Discussion:Tococa broadwayi is a rarely collected species of forests on Trinidad and Tobago and the Península de Paria in northeastern Venezuela. Vegetatively it is very similar to T. perclara; however, T. broadwayi has highly plinervate leaves (secondary nerves merging 3-7 cm from the base of the leaf), whereas the nerves in T. perclara merge only 0.5-1.7 cm from the base of the leaf. They also differ in the pubescence of the inframarginal portion of the leaf blade and of the outer calyx teeth, which are sparsely setose in T. broadwayi but densely setose in T. perclara

For discussion of other affinities and its placement in the genus, see T. meridensis.
