- "TYPE: Philippines, Luzon, seeds from Rapu Rapu Is., E. of Luzon, plant (female) cult. Sydney Botanic Gardens, 2006 (holo NSW 728768)."[NSW]
From the Latin nitida, shining, in reference to the extremely glossy
Very highly glossy leaves; small male cones, long spines on
microsporophyll tips, distinct teeth on megasporophyll tips, spongy endotesta in
Distribution and habitat:
Philippines only, usually in littoral forests on the north and
east of Luzon island.
This species occurs in coastal sites that have experienced severe
pressures from population increase and development. This habitat is also coming
under increasing pressure for aquaculture sites. Although probably not immediately
threatened, it is potentially vulnerable in the longer term.
