Description

Eucalyptus dolichocera is a mallee, rarely a tree, that typically grows to a height of 6 m (20 ft) and has rough, ribbony, grey-brown or red-brown bark on the lowest 2–3 m (6 ft 7 in–9 ft 10 in) of the trunk. Young plants and coppice regrowth have leaves arranged in opposite pairs, lance-shaped, slightly glaucous up to 70 mm (2.8 in) long and 15 mm (0.59 in) wide. Adult leaves are arranged alternately, lance-shaped, dull green, 70–130 mm (2.8–5.1 in) long and 13–25 mm (0.51–0.98 in) wide on a petiole 15–18 mm (0.59–0.71 in) long. The flower buds are arranged in groups of seven on a peduncle 10–16 mm (0.39–0.63 in) long, the individual buds on a pedicel 4–8 mm (0.16–0.31 in) long. Mature buds are oval, 13–20 mm (0.51–0.79 in) long and 3–5 mm (0.12–0.20 in) wide with a narrow conical operculum up to three times as long as the floral cup. Flowering occurs between October and November and the flowers are yellow to cream-coloured. The fruit is a woody cup-shaped to urn-shaped capsule 7–9 mm (0.28–0.35 in) long and 6–8 mm (0.24–0.31 in) wide with the valves enclosed below the rim. [2] [3] [4] [5]

Classification

Eucalyptus dolichocera was first formally described by the botanists Lawrence Alexander Sidney Johnson and Ken Hill in 1999 in the journal Telopea . The type specimen was collected by Ian Brooker and Donald Blaxell in 1975 about 80 km (50 mi) north east of Kalbarri on the North West Coastal Highway. [3] [6] The specific epithet (dolichocera) is derived from the Ancient Greek words dolichos meaning "long" [7] :494 and keros meaning "horn" [7] :195 referring to the long narrow operculum. [5]

This species belongs to the Eucalyptus subgenus Symphyomyrtus in the section Bisectae and the subsection Destitutae. It is similar in appearance to Eucalyptus moderata . [5]

Distribution

This mallee grows in laterite, limestone or sand on dunes, flats and sandplains and has a range from just north of Geraldton to Dowerin and Wongan Hills in the Avon Wheatbelt, Geraldton Sandplains, Mallee and Yalgoo biogeographic regions. [2] [5]

Conservation status

Eucalyptus dolichocera is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife [2]
