Eucalyptus cornuta, commonly known as yate, is a tree that occurs in an area between Busselton and Cape Arid and the islands of the Recherche Archipelago, in Western Australia. The Noongar peoples know the plant as Mo, Yandil, Yeit or Yate.
Its height can range between 2 and 25 metres in its native habitat, although in cultivation it is usually a medium to large tree ranging between 10 and 20 metres.
The tree produces clusters of long, horn-shaped buds that are followed by prolific, showy, green to yellow flowers between summer and winter. It has rough bark on the trunk which contrasts with the smooth bark of the upper part of the tree.
Eucalyptus cornuta was the first Western Australian eucalypt to be described, it was collected by Jacques Labillardière at Observatory Island (Archipelago of the Recherche) on 15 December 1792. The first description was given in Labillardière's Relation du Voyage à la Recherche de la Pérouse in 1800.
