Telor Buaya


The common Malaysian name for the timber of Homalium spp. (Flacourtiaceae). The ASEAN Standard Name for the timber, which is of Indonesian origin, is DELINSEM. Vernacular names applied include kayu batu (Peninsular Malaysia) and takaliu (Sabah). Major species include H. dictyoneurum, H. foetidum, H. grandiflorum and H. longifolium. The sapwood is not differentiated from the heartwood, which is reddish brown. Occasionally, a streaky corewood is produced in some trees.

Also known as Ateang and Roteang (Cambodia); Delingsem, Gia and Hia (Indonesia); Khen nang (Laos); Lance wood, Myaukchaw and Myaukugo (Myanmar); Malas (Papua New Guinea); Ampupuyot, Aranga and Aranga-babae (Philippines); and Kha nang (Thailand).


The timber is moderately hard to hard and moderately heavy to very heavy with a density of 720-995 kg/m3 air dry.


The timber is moderately durable.


It is easy to treat with preservatives, except for the corewood, which is not amenable.


Texture is fine and even, with usually straight but sometimes interlocked grain.


The timber falls into Strength Group A (Burgess, 1958).


It is difficult to resaw and cross-cut. Planing is slightly difficult and the planed surface is moderately smooth.


The timber seasons fairly slowly with only slight bowing and springing as the main sources of defects. 13 mm thick boards take approximately 3 months to air dry, while 25 mm thick boards take 4 months and 38 mm thick boards take 5 months.


Shrinkage is rather low, with radial shrinkage averaging 1.3% and tangential shrinkage averaging 1.9%.


The timber is suitable for temporary heavy construction, door and window frames, flooring, furniture, turneries and wooden pallets.
