Type. Arbusto de 4 m de altura con flores de color amarillo pallido, pequeñas; en el medio del Rio Sanariapo, cerca de su desembocadura, y casi completamente sumergido; la corteza es gris, la albura amarillenta y el duramen moreno, Puerto Ayacucho, Amazonas, Venezuela, 100 m, 25 May 1940, Llewelyn Williams 13051 (isotype, ? [male] fl. F).

The species superficially resembles 0. florulenta (Meissner) Mez but is distinguished by the possibly polygamo-dioecious flowers borne in sturdier, smaller and more strict inflorescences, and by its oblong-ellipsoid fruit subtended by a partially enclosing, shallow, suburceolate cupule. The prominent, loose reticulation of the leaves, as well as their shape, recalls the widespread Antillean species, Nectandra coriacea (Swartz) Griseb.

Ocotea sanariapensis bears fruit suggesting that of O. schomburgkiana which differs in the larger, hemispheric, frequently in the younger stages suburceolate cupule and broader, more elliptic, usually more coriaceous, loose but less regularly reticulate leaf-blades.

The recent collections of flowering material from The New York Botanical Garden expeditions to Venezuela bear dioecious flowers. The fruit-cupule tends to be more flaring and less suburceolate, and the leaves often more lanceolateelliptic. In other respects, however, they agree with the type of O. sanariapensis. The presence of dioecious flowers points to the possibility that the species may be polygamo-dioecious. However, the taxon is here discussed with the several species it most resembles.
