What the data sheet says

Color, grain and texture
Heartwood varies from light or pinkish-brown to dark brown, often with pinkish, grayish-green or blackish streaks, resembles European walnut; sapwood light brown, 3-4 in. in width. Grain generally interlocked and frequently wavy giving a broken stripe figure when quartered; texture medium; without distinctive odor or taste when dry; lustrous. Silica content of 0.19-1.08% is reported.
Working properties
Works rather well provided cutting edges are kept sharp. Silica deposits cause rapid dulling of knives so carbide-tipped cutters should be used. Gluing is satisfactory.
Durability
Rated as nondurable.
Uses
Furniture, cabinetwork, decorative veneers, paneling, joinery and millwork, flooring.
Where it grows
Confined to Northern Queensland (Australia), chiefly in the coastal districts.
