Cengal Pasir – Hopea odorata
T hingan is a landscape and timber tree native to tropical India and Southeast Asia, its natural range extending from Sri Lanka to the Andaman and Nicobar islands, and from Bangladesh to Myanmar BurmaThailand, Malaysia and Indochina. On open sites it is more typically 25 to 30 m 82 to 98 ft tall with gently ascending branches forming a pyramidal crown, becoming rounded as the tree ages. The bark is light- to dark-brown and roughened by vertical fissures and ridges.
They remain on the tree in hopsa seasons. Flowers white, small and insignificant and held in branched clusters arising at the sides and ends of the branches.
They bloom only every second spring and are followed by small egg-shaped nuts around jopea cm 0. The nut and wings are green when young, becoming brown when mature then detach to fall and glide on the wind. It produces a wood grouped with other Hopea species under the commercial name ‘Merawan’. Merawan has yellowish-brown heartwood darkening to olive-brown on exposure. It is lightweight to heavy, in the to kg per cubic meter 31 to 59 lbs per cubic ft range, and has variable natural resistance to rot and decay, ranging from non-resistant to very oodorata.
Variability in the weight and natural resistance of the wood is most probably due to differences in the wood properties between the different Hopea species, as well as differences in tree growth rates. Well-formed logs are sawn into boards and planks used mainly for furniture and cabinets, flooring and decking, interior joinery and millwork.
The trunk yields without wounding a hard, yellow, whitish or colourless resin that is soluble in turpentine. It is sometimes used as a varnish-over-paint, though it is reportedly somewhat inferior to better-known and more widely used varnish resins.
Thingan is commonly grown in its native range as a street and landscape tree for its shapely and stately form, as well as for the shade it gives. Unrestricted logging in its native range has led to a decline in natural populations. The resin in its powdered form is used in traditional medicine in Myanmar Burma as a styptic, with action that helps to halt bleeding when applied to wounds. Although it also grows naturally in seasonally dry areas with annual rainfall as low as mm, the trees are usually found close to rivers, stream and watercourses where the roots have access to groundwater during dry periods.
New plants are started from cuttings or seed, which lose their viability quickly, even under storage and are best sown within one to two weeks of harvesting the nuts. The seedlings are nursed under fifty percent shade until they are about 50 cm 1. Performs best on slow- to free-draining clay-loam, loam and sandy-loam soils of an acid to neutral nature, generally with a pH of 4. Despite its wide distribution, there does not appear to be any record of it being a weed or invasive species.
The nuts, though they can be dispersed far by the wind, lose their viability quickly and are reportedly highly susceptible to attack by weevils after they have landed on the forest floor. It unlikely to emerge as a problem weed or invasive species. This website is provided for general information only.
