Discussion
In foliage these two specimens appear conspecific, but unfortunately the flowers described for no. 2678 have been lost. Differences can be observed between these plants and the description of P. oreogenes, typified by Heilborn 488, also from Pichincha. Dr. Camp's specimens have the petioles slightly longer, the pedicels shorter, more slender, and glandular-pilose distally rather than glabrous, the calyx glandular-strigillose rather than glabrous, the stamens somewhat longer (about 9 mm. long), and the anther-tubules about 5 mm. rather than 2.5-3 mm. long. Our specimens differ from the allied P. sodiroi in the merely apiculate calyxlimb, the longer corolla, and in details of venation, in which characters they seem to agree with Sleumer's species.
