Discussion:
Type. VENEZUELA. Territorio Amazonas: Cerro Yutaje, Serraiña Yutaje, Northwest Ridge, 1400 m alt, 11 Feb 1953; shrub with stiff erect or ascending branches; leaves thickly coriaceous; corolla red, white-tipped, Bassett & C. K. Maguire 35149 (holotype NY). Paratype. VENEZUELA. Territorio Amazonas: Cerro Yutaje, left fork of Caño Yutaje, 1250 m alt, 12 Feb 1953, Maguire & Maguire 35181. This species simulates T. rigidiflora A. C. Smith in leaf shape, but differs in its shorfly racemose to subfasciculate inflorescence, more thickened pedicels, and non-reticulate-nerved upper leaf surface. It is more closely related to T.formosa Kl. (including T. roraimae Mansf.), from which it is distinguished by the longer anthers and corollas, and different leaf shape with narrower leaves rounded at apex.
