Description and Ethnobotany

Growth Form It is usually a tree with a single trunk up to 50 m tall, but in Singapore, it is usually only about 20 m tall.
Trunk Its bark is brown, and its twigs are conspicuously swollen at the nodes.
Foliage Its opposite, stalked leaves have leathery leaf blades that are usually oval or drop-shaped, and 4–15 by 2–10 cm, with rather sharp tips. Its leaf blades are dark green above, and yellow-green with brown spots below.
Flowers Its flowering shoots are divided into two equal, or three branches, and 1–6 cm long. Its flowers are stalkless, or shortly-stalked, white or pale-greenish, 3 mm long, and develop from the angles of leaves.
Fruits Its fruits are round berries up to 7 mm wide, and ripen from pink to red. Their fleshy pulp contain many seeds.
Habitat It grows in lowland and hill forests up to 1,800 m altitude. In Singapore, it grows in the landward edge of mangrove forest, and sandy beaches.
Similar This species resembles the common kelat (Syzygium lineatum) owing to its oval or round crown.
Associated Fauna It is the preferred local food plant for caterpillars of the teak defoliator moth (Hyblaea puera), the adult of which lays its eggs singly near the veins, and on the undersides of new leaf blade. Its flowers are insect-pollinated, and its red fruits are eaten by birds too.
Cultivation It is propagated by seed or terminal branch cuttings. Seeds need to be germinated immediately as their viability decreases rapidly. In Tropical Asia, fresh seeds have a viability of 45% to almost 100% within 1–3.5 months. Seedlings should also be planted in the nursery for two years after which, they may be transplanted to semi-shaded sites as they are sensitive to drought, and shade-tolerant. It requires full sun, and is tolerant of damp ground. It is a tree suitable for large gardens, roadsides, and parks.
Etymology Caralliam, translated from karalli, an Indian name; Latin brachiata, branched at right angles or arm-like, referring to the branching of the flowering shoot.
Ethnobotanical Uses Edible Plant Parts (Edible Fruits)
Food (Fruit & Vegetable)
Medicinal ( The leaves and bark are used medicinally against itch and septic poisoning.)
Timber & Products ( The wood is used for many construction purposes such as cabinet work, interior finish, railway carriages, pallets, and packing material. The wood is also a source of good-quality firewood and charcoal.)
