Abbreviated Description. Indumentum of appressed simple basifixed hairs, leaflets 1–3(–4), opposite to alternate, laterals 3 × 1.9–8 × 3.5 cm, elliptic to oblanceolate, terminal leaflet and unifoliolate leaflets 9 × 3.5–16 × 7.5 cm; inflorescence 1–10 cm long, a slender few-flowered thyrse, or sometimes a small raceme in female, petals 4–5, 1.5–2 mm long, fused for 1/3–1/2 their length, valvate, filaments completely fused in a staminal tube, margin with lanceolate to subulate lobes, anthers (4–)5, nectary absent, ovary 2-locular, locules with 2 collateral ovules, capsule 1.6–2.3 cm long, 2(–3)-valved, narrowly ellipsoid to oblong, smooth to weakly verrucose, with scattered appressed hairs or glabrous, seed 1(–2), completely surrounded by a thin arillode.

Distribution. Still known with certainty only from the southern Peten Peninsula of Guatemala and Belize and extending into northern Honduras. There is one doubtful sterile specimen from the Atlantic coast of Nicaragua which may belong to this species (Little 25172 - Nicaragua, Zelaya, 60 km NW of Puerto Cabezas (NW1483) (MO)).

Because of its unifoliolate leaves this species was grouped with the Colombian T. acuminata (FN28: 217 (1981)), but the ITS analysis does not support this. In this case geographical distribution is a better guide to relationship as the species is placed next to the co-occuring T. minutiflora and T. moschata .
