What is "eucalyptus marginata"

Jarrah \Jar"rah\, n. The mahoganylike wood of the Australian Eucalyptus marginata. See Eucalyptus.

Eucalyptus marginata is one of the most common species of Eucalyptus tree and is native to the southwest of Western Australia. The tree and the wood are usually referred to by the Aboriginal name jarrah. Because of the similar appearance of worked jarrah timber to the Honduras mahogany, jarrah was once called Swan River mahogany after the river system that runs through Perth.
