Notes
Since the description of this species in 1965, more specimens have been collected in Sabah, but it is now also known from two collections from Luzon. The large foliar glands positioned above the base remain a conspicuous character of P. kinabaluensis and by this character it is distinguishable from the large-fruited specimens of P. grisea var. grisea that occur on some Philippine islands, especially on Palawan.
