Description:
Species Description - Shrub, to 2.5-3.0 m tall; stems sparsely setose, the trichomes 0.5 mm long, caducous, the nodes glabrous. Leaves anisophyllous, lanceolate to narrowly elliptic, the apex acuminate, the larger ones 10-18 X 2.5-4.0 cm, base acute, the smaller ones 5-7 X 1.53 cm, the base obtuse, adaxial surface adpressed-setose, abaxial surface sparsely setose, light green, 3(-5)-nervate, membranaceous, entire; petioles 0.8-2.0 cm long, sparsely glandular-setose; domada free from the leaf blade, ovoid to fusiform, flattened on the abaxial surface, 1.5-2.0 X 0.8-1.3 cm. Inflorescence a terminal panicle of 3-8 flowers, 3-5 cm long, the axis flattened, sparsely glandular-setose. Flowers on pedicels 10-12 mm long, not flared at the apex; bracts unknown; hypanthium conical, with 5 wings that run from its base up to the torus, 5.5-6 mm long, essentially glabrous, but densely glandular-setose on the wings; outer calyx teeth lanceolate to subulate, with a broadening base, projecting up to 1.5 mm above the inner calyx teeth, inner calyx teeth ovate, fused at the base 1/2 of the total length, glabrous, 1.2-1.5 mm long; the ring inside the torus glabrous; petals 5, oblong, 9.0-9.5 X 4.0 mm, base oblong to slightly attenuate, emarginate, smooth, setulose at the apex; stamens all the same size; filaments 4.0 mm long, glabrous; anthers yellow; the connective with a dorsal-basal blunt tooth; thecae 4.5-5.0 mm long, opening by a ventrally inclined pore; ovary 3-locular, 1/3 inferior, the superior portion broadly conical, the apex with a corona of short glandular setae; style glabrous, 9 mm long; stigma funnelform, papillate. Fruits unknown; seeds unknown.

Discussion:
Tococa pauciflora is known only from one collection, in addition to the type. Due to the lack of material, this species was not included in the cladistic analysis. Based on floral morphology, T. pauciflora seems to be related to T. stenoptera and the remaining species with winged hypanthia, with the exception of T. rotundifolia. However, leaf and domatia morphology resembles that of species in the T. coronata clade.The number of the type collection is 3522 and not 2522, as cited by Triana (1871) and Cogniaux (1885; 1888; 1891).
