Description and Ethnobotany

Growth Form It is an evergreen, coniferous tree, up to 20 m tall.
Crown Its crown is broadly conical to dome-shaped in young trees, becoming irregular with age.
Foliage Its alternate, shortly-stalked leaves have leathery leaf blades that are narrowly lance-shaped, dark green, and 2.5–12 by 0.5–1.3 cm.
Reproductive Parts - non-flowering plant It is a dioecious species, with male and female cones borne on separate trees. The cream-coloured, cylindrical male cones develop in clusters of 3–5, and are each 2–4.5 cm long. The female cones develop singly, and consist of a single ovule up to 8 mm long on a fleshy, somewhat cylindrical receptacle about 6 mm long. The receptacle becomes red when the ovule becomes a mature seed, after pollination and fertilisation. The seed is green upon maturity, with a fleshy bright or dark red receptacle.
Others - Plant Morphology When grown in windswept conditions, tree may assume bent and gnarled form.
Habitat It usually grows along rocky and sandy seashores, in the landward edge of mangrove forest, and coastal cliffs.
Associated Fauna The seeds and the attached fleshy receptacles are eaten by birds and bats.
Cultivation It can be propagated by seed.
Etymology Genus name 'Podocarpus' means 'fruit foot', a reference to the swollen receptable holding the seed. Species epithet 'polystachyus' means 'many ears of corn', a description of the clustered male cones.
Ethnobotanical Uses Food (Fruit & Vegetable : The swollen, red receptacle is edible and sweet.)
Medicinal ( Leaves may be used to treat painful and rheumatic joints.)
Timber & Products ( It is an important source of softwood timber called Podo Wood or Podocarp timber. The wood is used as light to medium-weight softwood timber for interiorwork, beams, framing, furniture and oars. Wood is not weatherproof or insect resistant. )
Cultural / Religious ( Heritage Tree: There is currently one individual of Podocarpus polystachyus listed as Heritage Tree in Singapore. To find out more about this tree, please visit the Heritage Tree Register.)
