Eucalyptus transcontinentalis, commonly known as redwood[2] or boongul,[3] is a species of small to medium-sized tree, sometimes a mallet, that is endemic to the southwest of Western Australia.

Eucalyptus transcontinentalis is a tree, sometimes a mallet, that typically grows to a height of 12–25 m (39–82 ft) but does not form a lignotuber.

It has smooth white or greyish bark with occasional pale grey-yellow or pink blotches.

[2][4][5] Eucalyptus transcontinentalis was first formally described in 1919 by Joseph Maiden in the Journal and Proceedings of the Royal Society of New South Wales from specimens he had collected from near Kalgoorlie in 1909.

[8] Redwood is found on flats and low rises on red sandy loam in open forest and woodland in the southern and central goldfields from the Frank Hann National Park near Salmon Gums, east to near Norseman and north to near Menzies.
