Stapf from Mount Kinabalu in Borneo, Sabah, Malaysia by its stout glabrous branchlets, coriaceous glabrous leaf blades with rounded apices, and 4-7 mm-long pedicels with a mixture of muriculate trichomes and pale ferrugineous nonglandular trichomes. It differs from this species most readily by its green or slightly flushed pink petioles 4-7 mm long (vs vivid red and 10-13 mm), wider leaf blades [7-7.5 cm vs (2.5-)3.5-5(-7.5) cm], acute calyx lobe apices (vs obtuse), and lavender mature fruiting calyx (vs black). It is also similar to

(Merrill) Sleumer, distinguished by "Leaves broadly pointed to rounded with the terminal gland forming a short mucronate point the largest leaves up to 5 cm long" vs "Leaves acuminate, with a narrowly acute apex, the largest leaves more than 6 cm long," respectively. Because the new species possesses leaves that are rounded (or strongly emarginate) at the apex but are 8.3-9.7 cm long (the larger ones), the new species does not match either of these leads. Thus, it can be distinguished from all other Philippine
