Description and Ethnobotany

Growth Form It is a shrub or tree that can grow up to 18 m tall, attain 100 cm in girth size, with oval to rounded crown.
Trunk Reddish-brown and papery-flaky in mature specimens.
Foliage It has opposite, short-stalked leaves that are leathery, lance-shaped, 3–11 cm long by 1.1–5.5 cm wide, purplish pink when young, and each has a pointed leaf tip, 1 vein running parallel to the leaf margin, and 10–14 pairs of side veins. Mature leaves dark glossy green above, paler green below, with numerous secondary veins spaced 2-3 mm apart and at 80°-85° angle from midvein, veins conspicuous on upper leaf surface and slightly raised on bottom surface, intramarginal vein indistinct and around 1mm from leaf's edge; young leaves purplish to brownish pink and very glossy.
Flowers It produces bisexual flowers that are white, faintly fragrant, and found in up to 2.5–4 cm long flower clusters located at ends of its branches, or axils of its leaves.
Fruits It produces fleshy fruits that are oblong or oblong-round, 0.5–0.7 cm long, white, and each contains 1 greenish seed. The small berries ripen from greenish to white (freckled with several brownish spots), persistent sepals on base, single seed, relatively thin pulp is soft and fleshy, with fresh scent reminiscent of Syzygium aqueum (Jambu Air, Water Apple), eaten by birds, squirrels and fruit-eating animals.
Habitat It grows in lowland to montane forests, which includes secondary forests, and also in swamps, and by rivers, and seashores. In Singapore, it can be found in Central Catchment Nature Reserve, Labrador Nature Reserve, Lazarus Island, Mount. Faber, Pulau Tekong, Pulau Ubin, and Singapore Botanic Garden.
Similar May be confused with the taller Syzygium lineatum, but the latter species can be differentiated by its bigger, matte dark green mature leaves with more closely-spaced secondary veins and distinct marginal vein, light green young leaves, larger fruits (10 - 13mm across), and pinkish-grey trunk.
Associated Fauna Its flowers produce nectar that attracts insects like bees, butterflies and day-flying moths (Syntomis huebneri). It is also the larval host plant for the Copper Flash butterfly (Rapala pheretima sequeira). Its fruits are eaten birds, squirrels, and other fruit-eating animals.
Cultivation Hardy plant, tolerates poor soils and salt spray. Propagate by seeds, stem cuttings or air-layering.
Etymology Genus epithet 'Syzygium' derived from 'syzygos' (Greek for 'joined'), alluding to the opposite paired leaves. Species epithet 'zeylanicum' refers to Ceylon (old name for Sri Lanka), where the species is also naturally distributed.
Ethnobotanical Uses Edible Plant Parts (Edible Fruits)
Food (Herb and Spice;Fruit & Vegetable : Sweetly scented berries are edible, although there is not much pulp. )
Medicinal ( Leaf Infusion used to treat diarrhoea, decoction of leaves and roots used as vermifuge, and for their anti-diabetic and anti-rheumatic properties. )
Timber & Products ( Reddish-brown wood used as firewood, or for building houses, rafts and agricultural tools. )
[Others]: Folk legend has it that rubbing leaves on chest of elephant makes it docile.
