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.
Description
Eucalyptus yarriambiack is a robust, spreading tree that typically grows to a height and spread of 10 m (33 ft) 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 90 mm (3.5 in) long and 11 mm (0.43 in) wide. Adult leaves are olive green to bluish green and leathery, narrow lance-shaped to lance-shaped or curved, 50–100 mm (2.0–3.9 in) long and 8–15 mm (0.31–0.59 in) wide on a petiole 9–14 mm (0.35–0.55 in) long. The flower buds are arranged in leaf axils in groups of seven to eleven on a peduncle 6–11 mm (0.24–0.43 in) long, the individual buds on pedicels 2–4 mm (0.079–0.157 in) long. Mature buds are oval to slightly club-shaped, 4–6 mm (0.16–0.24 in) long and about 3 mm (0.12 in) 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 4–6 mm (0.16–0.24 in) long and 3–4 mm (0.12–0.16 in) wide with the valves below rim level.[2][3]
Taxonomy and naming
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][4] The specific epithet (yarriambiack) refers to Yarriambiack Creek near where the species occurs and is in turn of Aboriginal origin.[3]
Distribution and habitat
This eucalypt is only known from a single site between Brim and Beulah in a usually dry watercourse.[2][3]
