Species

Gymnosperms > Cupressales > Podocarpaceae > Podocarpus l'hér. ex

Characteristics

Tree 1-20 m tall, 3-45 cm diam., most commonly c. 6 m. Foliage buds 1.5-3 mm long. Juvenile leaves generally within the upper range of adult leaf size, linear to linear-lanceolate, acute and almost apiculate, sometimes mixed with more typical adult leaves. Adult leaves linear to oval, 3-10 cm by 6-13 mm, more or less acute to rounded at the apex, narrowed abruptly at the base to a 1-3 mm peduncle, margin flat or nearly so; midrib above a sharp ridge 0.3-0.4 mm wide and 0.2 mm high. Buds for pollen cones sessile. Pollen cones 2-4 cm long, clustered in groups of up to at least five. Seed-bearing structure on a 1-6 mm peduncle; foliola 1-1.5 mm long, falling; receptacle 7-10 mm long. Seed with its covering 7-9 by 5-7 mm.

Environment

The main occurrences are at low altitudes and fall apart for the major part into three ecologies. First, the principal habitat is sandy beaches, often gregariously bordering the sea at hightide mark and sandy coastal bluffs and low outcrops, also mentioned for sandy ridges in the mangrove. On coastal granite and limestone rocks the trees are gnarled. Second, it is often frequent on lowland coastal kerangas and sandy 'pandangs' (degraded heath forest) and sandy heath forest (Menchali For. Res., Pahang). These two habitats are typical in the Sunda Land. Third, on limestone hills inland, for instance in Malaya and the Philippines, in Obi, Waigeu, and the Vogelkop Peninsula in New Guinea at 180, 280 and 550 m, at 1000 m in Palawan. In East Malesia these occurrences are scattered.The bole is sometimes recorded to be fluted. The tree is found in Obi exceptionally tall, 40 m, with a clear bole of 25 m and 38 cm diam., and buttresses of 1 by 1.5 m. A most interesting ecology.
More
Found mainly on sandy beaches and bluffs, often on the land side of mangrove at or just above the high tide mark. Also in coastal lowland 'kerangas' forest, and on limestone hills and plateaux inland at elevations to 550 metres.
