Eucalyptus yarriambiack is a species of small, spreading tree that is only known from a single population in Victoria, Australia. It has rough, fibrous to flaky bark on the trunk, smooth bark above, narrow lance-shaped to elliptical adult leaves, flower buds in groups of seven to eleven, white flowers and hemispherical to cup-shaped fruit.
Eucalyptus yarriambiack is a robust, spreading tree that typically grows to a height and spread of and often has a few thick trunks. It has rough, greyish brown, fibrous to flaky bark on the trunks, smooth, light grey or brownish bark above. Young plants have narrow elliptical to narrow lance-shaped leaves that are about long and wide. Adult leaves are olive green to bluish green and leathery, narrow lance-shaped to lance-shaped or curved, long and wide on a petiole long. The flower buds are arranged in leaf axils in groups of seven to eleven on a peduncle long, the individual buds on pedicels long. Mature buds are oval to slightly club-shaped, long and about wide with a conical operculum that is shorter than the floral cup. Flowering occurs in autumn and the flowers are white. The fruit is a woody hemispherical to cup-shaped capsule long and wide with the valves below rim level.[1] [2]
Eucalyptus yarriambiack was first formally described in 2012 by Kevin James Rule in the journal Muelleria from specimens he collected in 2005 near Brim.[3] The specific epithet (yarriambiack) refers to Yarriambiack Creek near where the species occurs and is in turn of Aboriginal origin.
This eucalypt is only known from a single site between Brim and Beulah in a usually dry watercourse.
