to salmon pink on the branches.
Wood
description [more

Heartwood is dark brown with obvious growth rings.
Wood
density [more
info]
Green density is about 1165 kg/m3, air-dry density about 1130 kg/m3,
and basic density about 870 kg/m3.
Shrinkage
[more
info]
Tangential and radial shrinkage are about 7.2 and 6.0 per cent respectively.
Workability
[more
info]
Goldfields craftsmen rate black morrel as good
for machinability, screwholding, stability and gluing, and excellent for
turning, boring, sanding and finishing.

Strength
group and properties [more
info]
Green and dry strength groups are (S2) and (SD2), based on the air-dry
density. Data from Melotte (1997) in the table below indicate SD2. Hardness
tests were done by CALM in 1998.
