Botanical Name: Manilkara Kanosiensis

Heartwood colour ranges from a light red or brown to a darker brick red; tends to darken with exposure to light. Thin sapwood is a pale yellow to pink. Grain tends to be interlocked or wavy with a medium to coarse texture. Some boards can contain gum pockets or streaks as a naturally occurring defect. Jarrah can also exhibit a curly figure.

Manilkara is rated as very durable regarding decay resistance, and it is also quite resistant to insect attack.

Manilkara tends to be difficult to machine on account of its high density and interlocked grain. It also has a moderate blunting effect on cutting edges. Manilkara turns, glues, and finishes well and commonly used in flooring, heavy construction, veneer, cabinetry, outdoor furniture, and turned objects.

Because of its great durability and common occurrence, Manilkara is a useful timber for exterior projects in Australia. Its vibrant red color, and high density add to its marketability for use as a flooring material.
