Description

A disjunct outlier population of Eucalyptus oblonga at Bateau Bay, Forresters Beach and Tumbi Umbi in the Wyong local government area.

Narrow-leaved Stringybark (family Myrtaceae) is a tree to 15 m high with persistent, grey to red-brown, stringy bark on the trunk and larger branches.

Its juvenile leaves are broad-lanceolate, glossy green and discolorous. The adult leaves are lanceolate, 6-9 cm long, 1.4-2.8 cm wide, glossy green and concolorous. Flower clusters are 7- to = 11 flowered on narrowly-flattened or angular stalks 6-12 mm long. Individual flower stalks on the clusters are 1-2 mm long. Flower buds are cylindrical or tapering towards each end, 6-7 mm long, 2-3 mm diameter. The caps of the buds (calyptra) are conical and at least as long and as wide as the bases. Fruit are spherical or hemispherical, 6-8 mm long, 6-9 mm diameter, with a flat to raised disc and valves at rim-level or exserted.

Distribution

The species occurs from Gosford to the Appin and Waterfall districts. The disjunct outlier population at Bateau Bay, Forresters Beach and Tumbi Umbi includes occurrences on the Patonga Claystone Formation and derived soils, corresponding to the Woodburys Bridge Soil Landscape. Here it is at the eastern limit of the species' range and is of significant conservation value because elsewhere the species occurs on sandstone. The population of Eucalyptus oblonga consists of about 20 trees.

Habitat and ecology

  • Normally found on in dry open forest with infertile sandy soils on sandstone. The population at Bateau Bay occurs on coastal sands.
