General Characteristics = Heartwood varies from a pale yellowish brown to dark chocolate brown with lighter markings most conspicuous on flat-sawn surfaces; sapwood yellowish white, clearly demarcated. Texture medium to coarse; grain typically interlocked, sometimes irregular; slightly greasy feel; without odor; wet sawdust may cause dermatitis; occasional large "stone" deposits of calcium carbonate.
Grain = Interlocked, Has a fairly coarse texture and open pores. Grain is usually wavy or interlocked.
