Notes
This species is quite homogeneous in appearance. It resembles some specimens of P. arborea var. alticola, but differs in the shape of the fruits: transversely ellipsoid and nearly always broader than long, rarely subglobular, in var. alticola, ellipsoid and always longer than wide in P. oocarpa. Flowering specimens are sometimes more difficult to distinguish, but var. alticola has more and often longer stamens (16-40, filaments up to 6 mm). The crater-like glands that sometimes occur on the stipules of var. alticola, were not seen in P. oocarpa.
