Description

Gibraltar Rock Apple is one of the ‘apples’, eucalypt-like trees with paired leaves. A member of the Angophora bakeri group, Angophora exul is distinguished by the very narrow leaves with long, slender petioles. It has rough grey bark and grows as a small tree up to 10 m tall. The adult leaves are smooth and straight, 5 - 12 cm long and 4 - 7 mm wide with a tapered tip. The two sides of the adult leaves are slightly different colours, with the underside paler than the top. Flowers occur at the end of the branches in groups of 3-7. The ribbed gumnuts are cup-shaped and 5 - 8 mm long and 5 - 7 mm wide.

Distribution

Angophora exul is very rare, known only from a single small stand on Gibraltar Rock, west of Tenterfield

Habitat and ecology

  • Flowering period is unknown. Seed is probably dispersed locally by wind or gravity, and there is no dormancy mechanism.
  • Gibraltar Rock Apple is a rare species occurring only on open scree on a ridge of acid volcanic outcrops. The habitat is dry open woodland on the steep south-west slopes and crest of the outcrop, with skeletal to shallow loam soil.
  • Associated vegetation is described as dry sclerophyll forest of Eucalyptus melanophloia dominant with Eucalyptus caleyi and Eucalyptus dealbata, as well as shrubby woodland of Angophora exul, Angophora leiocarpa and Eucalyptus dealbata with Bertya cunninghamii subsp. rupicola, Westringia amabilis and Lomandra sp. aff. glauca.
