Description
Silvertop Ash has a narrow sapwood, which is not clearly distinguishable from the heartwood. Its heartwood is brown and sometimes pinkish in colour and often features the grain interlocked with growth rings. With a medium texture, silvertop ash is also recognisable by the common occurrence of gum veins, the markings of pinhole borers and pencil streaks.
