Both P. apicata H.B.K. and P. pittieri Standl. were described from the Silla de Caracas, but practically all present day collections from the Silla and adjacent areas fall within the range of Standley’s taxon with puberulous branches of the inflorescence, whereas P. apicata refers to a taxon with glabrous inflorescence branches and with the fruit possessing a persistent projecting apex. The latter character is not present in the numerous fruiting collections examined of P. pittieri. Only two present-day collections, cited above (Steyermark 91566 and Tamayo 226) show this apical projection of the fruit. The leaves in these collections vary on the lower side from completely glabrous on the surface with spreading pilose or hirsute hairs on the midrib, thus matching those of the type specimens from the Paris herbarium.
The Steyermark and Tamayo collections both show a strongly gibbose corolla with conspicuous bosses or tubercles in the sinuses at the base of the corolla lobes, a character not mentioned in the original description of P. apicata. The length of the corollas, 12-13 mm, fits the description of the species, given as “flores . . . semi-pollicares.” Further points of identity between the present day collections cited above and the type specimens at Paris are the sessile inflorescence, glabrous branches of the inflorescence, petiole length, leaf shape, and 12-14 pairs of lateral nerves of the leaf blades.
