The common Malaysian name for the timber of Engelhardtia spp. (Juglandaceae). The ASEAN Standard Name, which is of Indonesian origin, is KAYU HUJAN. Vernacular names applied include entalun (Sarawak), paar (Peninsular Malaysia) and teraling (Peninsular Malaysia). Major species include E. apoensis, E. roxburghiana, E. serrata and E. spicata. The sapwood is grey with a pink tinge or grey-brown with a purple tinge and is not sharply defined from the heartwood, which is light pink when fresh and darkens on exposure to light brown. A core of black or streaky timber is developed in some trees.

Also known as Moglaipoma (India); Kayu Hujan and Ki hujan (Indonesia); Engel (Papua New Guinea); Lupisan (Philippines); and Kha hot (Thailand).


The timber is soft to moderately hard and light to moderately heavy with a density of 380-715 kg/m3 air dry.


The timber is non-durable.


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


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


It is reputed to be easy to saw and work but the planed surface is rough.


The timber has been observed to season fairly rapidly with end-splitting and surface-checking as the main defects.  


The timber is suitable for light construction under cover, weather boards, agriculture implements, mouldings, ornamental items, gunstocks and plywood. The darker corewood may be used for furniture.
