The Tree
T. serratifolia is a canopy tree, unbuttressed or with low buttresses, about 37.0m high and a diameter of about 1.0m, although in some parts of its range diameters of about 2.0m are found. Clear cylindrical boles 15.0m to 18.0m are common.

The Timber
The heartwood is yellowish green when first cut, turning a light to dark olive-brown with lighter or darker streaks. The sapwood is distinct, greyish-white in colour, and 38mm to 88mm wide. The texture is fine; the grain is straight to occasionally irregular, and the lustre is low to medium. Pores in the heartwood, which appear as fine yellow dots, are filled with a yellowish powder (lapachol), and appear on longitudinal surfaces as yellow lines. The wood is cold to the touch and often appears oily; very fine ripple marks are usually present.

Drying
Despite its relatively high density, ipi is a fairly easy wood to dry. It dries rapidly with slight warping, cupping, twisting, end and surface checking occurring. A slow drying kiln schedule is recommended.

Strength
The wood is hard, tough and strong, and compares favourably with greenheart.

Working Qualities
Difficult - Ipi is moderately difficult to work especially with hand tools, and has a blunting effect on cutting edges. A good finish is usually obtained when planing or moulding plain-sawn material, but a cutting angle of at least 150 is recommended to eliminate chipping of quarter-sawn stock. The timber stains and polishes well and requires little grain-filler, but pre-boring is required before nailing to prevent splitting and bending of nails.
