General Description

Sapwood is not clearly defined from the heartwood, which is light yellow-green, sometimes with a pink tinge and darkening to grey-green on exposure. Grain is shallowly interlocked. Texture is rather f ine and even. Vessels are medium-sized, moderately numerous, solitary and in radial groups of 2 to 3, the majority solitary. Wood parenchyma is sparse, consisting of very narrow borders to vessels and are not discernible even with a hand lens; occasional metatracheal bands of parenchyma are present. Rays are moderately fine and distinct on the tangential surface. Horizontal gum canals are present.
