Eucalyptus gomphocephala is a species of tree, also known as Tuart, in the genus Eucalyptus, the Noongar peoples know the tree as Moorun, Mouarn, Tooart or Tuart. Native to the southwest of Western Australia the tree grows to over 35m tall. As a durable hardwood the timber is sought after for scantlings, structural timber, the construction of railway carriages, and boat building. The colouring and grain pattern of the timber also makes it a popular choice for furniture manufactures, due to over logging the Tuart is a protected tree with conditions placed on logging.
The Tuart has box-like rough bark through the length of the trunk to small twigs. Leaves are stalked, alternate, lanceolate or falcate to 12 x 2 cm, slightly discolorous to concolorous, glossy, light green and thin. White flowers appear in mid summer to mid autumn.
The distribution range of the species is a narrow coastal corridor within the Swan Coastal Plain, extending inland five to ten kilometres, a continuous strip south from Yanchep to Busselton. Outlying patches of the tree are found to the north of Yanchep and further inland where rivers intersect the range.
