TREE CHARACTERISTICSMedium sized tree; height to 20 m, DBH to 60 cm; bole short, cylindrical, attimes angular, crooked, tapering; branches somewhat slender, twisted so are thebranchlet; crown irregular in shape, quite dense; buttresses high, symmetrical, planktype, spreading to 4 m; bark tough, Uirty-brown,flaky-scaly, flaking and sloughingin time into small, irregular-shaped sheets, leaving conspicuous flat scars on-thebole of the surface; leaves oblong or linearly-oblong, glaucous beneath, simplealternate, entire.4. WOOD DESCRIPTI<strong>ON</strong>Sapwood is not sharply marked off from heartwood, which is grayish or palereddish-brown; grain straight; texture moderately fine; hard; and heavy. Growthrings indistinct to fairly distinct. Pores barely visible to the naked eye: solitary andin radial multiples usually 2-3, the multiples predominating; perforation platessimple. Parenchyma visible with a hand lens, abundant, diffuse as short tangentiallines between rays forming a mesh-like pattern. Rays not visible Ito the naked eyeon cro~s section. Ripple marks due to storied arrangement of the rays on tangentialsurface_ are distinct with a hand lens.28
