Discussion:

Psychotria spicata M.-Arg., Flora 59: 550. 1876, not Benth. 1841.

Psychotria vaupesana Standi, ex Steyerm., Acta Biol. Ven. 4: 101. fig. 50. 1964.

Type. Prope San Carlos ad Rio Negro, Amazonas, Venezuela, 1853-54, R. Spruce 3089.

This species resembles P. podocephala, P. paupertina, P. moroidea, and P. cephalantha, but may be distinguished from all of these by the more elongated inflorescence and puberulent exterior surface of the corolla. Both P. spiciflora and P. podocephala were originally collected in Venezuela at San Carlos de Rio Negro. The tertiary venation in P. spiciflora is more elevated and more prominent, as well as closer together, than in P. podocephala.
