Description

Ceriops tagal is a medium-sized tree growing to a height of 25 metres (80 ft) with a trunk diameter of up to 45 cm (18 in). The growth habit is columnar or multi-stemmed and the tree develops large buttress roots. The radiating anchor roots are sometimes exposed and may loop up in places. The bark is silvery-grey to orangeish-brown, smooth with occasional pustular lenticels. The leaves are in opposite pairs, glossy yellowish-green above, obovate with entire margins, up to 6 cm (2.4 in) long and 3 cm (1.2 in) wide. The flowers are borne singly in the leaf axils; each has a long stalk and a short calyx tube, and parts in fives or sixes. The paired stamens are enclosed in the petals which open explosively when disturbed. The ovoid fruits are up to 3 cm (1 in) long suspended from the shrunken calyx tube. Brown at first, they change colour as they mature and the hypocotyl emerges. The hypocotyl is long and slender, growing to about 35 cm (14 in) long, and is ribbed, a characteristic that distinguishes this mangrove from the smooth-fruited yellow mangrove (Ceriops australis).[5][6]

Distribution and habitat

Ceriops tagal grows naturally in eastern and southern Africa, Madagascar, Seychelles, India, Maldives, China, Indo-China, Malesia, Papuasia, the Caroline Islands, New Caledonia and Australia.[1][3] Its habitat is in brackish water areas near tidal lines.[1][5]

Uses

The durable wood is used in house construction. It is also used in the manufacture of charcoal,[5] and is favoured as firewood, being second only to Rhizophora spp., and a dye can be extracted from the bark.[1] Among the mangrove species, its bark and sap yield red and black dyes which are used in batik and tanning leather.

In the Philippines, the extracts (barok) from the dried bark (marka tungog or tangal) are used as bittering and fermenting agents for the traditional bahalina palm wines, giving them a deep brown-orange color and a bitter tangy aftertaste. It is also used to tan and dye leather.[7]
