Cycas nitida

Cycas nitida K.D.Hill & A.Lindstr, "Telopea 12(1):142–143, fig. 6 " (2008). H—NSW
"TYPE: Philippines, Luzon, seeds from Rapu Rapu Is., E. of Luzon, plant (female) cult. Sydney Botanic Gardens, 2006 (holo NSW 728768)."[NSW]

Etymology: From the Latin nitida, shining, in reference to the extremely glossy leaves.

Distinguishing features: Very highly glossy leaves; small male cones, long spines on microsporophyll tips, distinct teeth on megasporophyll tips, spongy endotesta in seed.

Distribution and habitat: Philippines only, usually in littoral forests on the north and east of Luzon island.

Conservation status: 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. IUCN (2001) Red List status NT.
