Discussion
Type. Tree 4-5 m, buds pink, occasional on upper escarpment slopes east of Camp 3, Cerro de la Neblina, Terr. Amazonas, Venezuela, alt. 1700 m, 27 Dec 1953, Bassett Maguire, John J. Wurdack, & George S. Bunting 36918 (holotype US 2342540).
T. erioneura has completely eglandular lower leaf surface hairs and a blade length/width ratio of 3-4 rather than 2-2.5; the flowers of both species show no differentiating characters. Other close relatives of T. tepuiensis include T. desiliens Gleas. (with glandular-setose stems, inflorescence, and hypanthium) and T. cinnamomea Tr. (with non-glandular hairs, basally nerved leaf blades, and dorsally tilted anther pores). Both T. subciliata (DC.) Tr. and T. planifolia Benth. differ at least in the basally tapered hypanthia, more prominent external calyx teeth, and pubescent ovaries.
