The Standard Malaysian Name as well as the ASEAN Standard Name for the timber of Pterospermum spp. (Sterculiaceae). Vernacular names applied include litak (Sabah). Major species include P. diversifolium, P. jackianum, P. javanicum and P. subpeltatum. The sapwood is creamy white to light yellow-brown and merges gradually into the heartwood, which is light red-brown and darkens to brown on exposure.

Also known as Hathipaila and Mayene (India); Badjo, Bajoe, Bajur Sulawesi, Banjoro, Bayur, Bodja, Medang lintah and Roembei (Indonesia); Taungpetwun (Myanmar); Bayok and Kulatingan (Philippines); and Welang (Sri Lanka).


The timber is soft to moderately hard and has been classified under Light Hardwood with a density of 385-705 kg/m3 air dry.


The timber is non-durable under exposed conditions but would be moderately durable under cover.


The timber can be easily treated with preservatives.


Texture is moderately fine to slightly coarse and even with straight or shallowly interlocked grain.


The timber falls into Strength Group C (Burgess, 1958) or SG 6 (MS 544:Part 2:2001).


It is easy to work and produces a smooth finish.


The timber seasons fairly fast with little degrade except for sapstaining. 13 mm thick boards take 1.5 months to air dry, while 38 mm thick boards take 3 months.


Shrinkage is high. Radial shrinkage averages 2% while tangential shrinkage averages 3.7%.


The timber is suitable for temporary light construction, flooring, cladding, planking, joinery, cabinet making, interior finishing, panelling, mouldings, tool handles for non-impact purposes, furniture, joists and staircase (apron lining, baluster, balustrade, carriage, handrail, riser, stringer, sprandrel framing, tread, bullnose, round end and winder).
