Description

Eucalyptus terphroclada is a mallee that typically grows to a height of 4–5 m (13–16 ft) and forms a lignotuber. It has smooth, reddish, brownish and grey bark and branchlets covered with white, powdery granules. Young plants and coppice regrowth have elliptical to lance-shaped leaves that are 30–90 mm (1.2–3.5 in) long, 15–35 mm (0.59–1.38 in) wide and petiolate. Adult leaves are the same shade of glossy green on both sides, lance-shaped, 50–100 mm (2.0–3.9 in) long and 9–15 mm (0.35–0.59 in) wide on a petiole 7–20 mm (0.28–0.79 in) long. The flowers buds are arranged in leaf axils in groups of nine to thirteen on a pendulous, thin, flattened, unbranched peduncle 12–40 mm (0.47–1.57 in) long, the individual buds on pedicels 5–11 mm (0.20–0.43 in) long. Mature buds are 24–32 mm (0.94–1.26 in) long and 5–8 mm (0.20–0.31 in) wide with a horn-shaped operculum up to four times as long as the floral cup. Flowering occurs from October to February and the flowers are pale lemony yellow. The fruit is a woody barrel-shaped to cup-shaped capsule 8–14 mm (0.31–0.55 in) long and 6–10 mm (0.24–0.39 in) wide with the valves near rim level.[3][4][5]

Taxonomy and naming

Eucalyptus tephroclada was first formally described in 1992 by Lawrie Johnson and Ken Hill in the journal Telopea from specimens collected near Bruce Rock in 1986.[4][6] The specific epithet (tephroclada) is from ancient Greek words meaning "ash-grey" and "twig", referring to the powdery covering on the twigs.[4]

Distribution and habitat

This mallee grows in woodland with scattered mallee scrubs in scattered places between Quairading, Southern Cross, Kukerin and Hyden.[3][4]

Conservation status

This eucalypt is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[5]
