Eucalyptus surgens | |
Eucalyptus surgens is a species of mallee that is endemic to a small area on the south coast of Western Australia. It has rough bark near the base of the stems, glossy green lance-shaped leaves, flower buds in groups of seven, creamy yellow flowers and cup-shaped to cylindrical fruit.
Eucalyptus surgens is a mallee that typically grows to a height of 2.5 m (8 ft 2 in), forms a lignotuber and has smooth bark apart from some rough bark near the base of the trunk. Young plants and coppice regrowth have dull bluish green, broadly lance-shaped to egg-shaped leaves that are 55–60 mm (2.2–2.4 in) long, 25–35 mm (0.98–1.38 in) wide and petiolate. Adult leaves are the same shade of glossy light green on both sides, lance-shaped, up to 100 mm (3.9 in) long and 20 mm (0.79 in) wide. The flower buds are arranged in leaf axils on a thick, unbranched peduncle 3–5 mm (0.12–0.20 in) long, the individual buds on short pedicels. Mature buds have a bell-shaped floral cup and a cap-shaped operculum about 15 mm (0.59 in) long, 8 mm (0.31 in) wide and shorter than the floral cup. The flowers are creamy yellow and the fruit is a woody, cup-shaped to cylindrical capsule about 12 mm (0.47 in) long and 9 mm (0.35 in) wide with the valves below rim level. [2] [3]
Eucalyptus surgens was first formally described in 1993 by Ian Brooker and Stephen Hopper in the journal Nuytsia from specimens collected by Hopper near Toolinna Cove in 1989. [2] [4] The specific epithet (surgens) is a Latin word meaning "rising", referring to a prominent vertical scar on the rim of the fruit. [2]
This mallee is only known from the type location near the coast on the western edge of the Nullarbor Plain. [2]
