Type. Tree 12 m, flowers greenish-white, occasional along banks of Cañon Grande River, SSE of Cumbre Camp, Cerro de la Neblina, Rio Yatua, Amazonas, Venezuela, 1100-1150 m, 26 Dec 1957, Bassett Maguire, John J. Wurdack & Celia K. Maguire 42521 (holotype, [female] fl. NY).
The yellow-green, perfectly elliptic leaves of this species are in strong contrast with the loosely flowered, exceedingly slender, tenuous inflorescences. Again, it is difficult to relate this to any of the known s]>e('ies of the genus. The leaves and habit of the inflorescences strongly suggest Aiouea, but the flowers are tvpical of Endlieheria.
