General Description

Sapwood is well-defined. Heartwood is light yellow-brown with a green tinge, darkening to deeper shades of yellow-brown or brown. Grain is interlocked and sometimes wavy. Texture is moderately coarse and even. Vessels are with simple perforations and medium-sized, moderately few in number, mostly solitary, the rest in radial, tangential or oblique pairs and radial multiples of up to 4 in a series, fairly evenly distributed. Tyloses are occasionally present but sparse. Wood parenchyma is of both apotracheal and paratracheal types. Apotracheal type occurs as irregularly spaced bands containing resin canals whereas the paratracheal type occurs as incomplete vasicentric, narrow vasicentric or aliform, tending to locally confluent. Rays are medium-sized, visible to the naked eye on the cross-section. lntercellular canals of both vertical resin canals and horizontal canals are characteristic. Vertical canals are smaller in size than the vessels or as large, arranged in continuous tangential series.
