"Tree 2.5-20 m tall. Foliage buds 4-9 mm long. Juvenile leaves linear, acute, 4-9 cm by 5-9 mm. Adult leaves linear to ovate, 2-5 cm by 4-7 mm, acute to almost rounded at the apex, narrowed at the base to a 1-3 mm petiole; midrib above weakly developed, 0.5-0.7 mm wide and 0.1-0.2mm high and often collapsing upon drying leaving a weak depression w'ith a narrow ridge in the centre, upper hypoderm continuous. Pollen cones 1-1.5 cm, sessile, solitary or occasionally a pair; apex of microsporophyll triangular, up to 0.8 mm long. Seed-bearing structure on a peduncle at least 3 mm long; foliola 4 mm long; receptacle formed of two unequal bracts; mature seed unknown... The leaves generally resemble those of P. pilgeri, a species which is not otherwise similar at all" (de Laubenfels 1988).
Borneo: Sabah: Endemic to Mt. Kinabalu at 1200-2400 m elevation. Typically on moss forest ridges, mostly or always on ultramafic soils (de Laubenfels 1988).
The IUCN reports that this species is "vulnerable" to extinction in the wild because the population is already very small and restricted in distribution, and could be devastated by a chance occurrence that could be caused by human action.
