Origin of Scientific Name
Eucalyptus - Greek eu = well + calyptos = covered, referring to the operculum or cap covering the stamens in the bud.
erythrocorys – Greek erythro = red + corys = helmet, referring to the operculum.
Small tree or mallee 3 to 8 metres high, with smooth, creamy new bark, oxidising to brown and often with rough patches of darker bark. Leaves are dark green and sickle-shaped. The large, scarlet-red flower buds are rectangular in shape and precede squarish yellow flowers up to 7 centimetres across in groups of three with the stamens in four bundles, one at each corner. The flowers are then followed by helmet-shaped fruit.
