Eucalyptus parramattensis, commonly known as the Parramatta red gum or drooping red gum,[2] is a species of small to medium-sized tree that is endemic to eastern New South Wales. It has smooth, mottled bark, lance-shaped to curved adult leaves, flower buds in groups of seven, white flowers and hemispherical fruit.

Description

Eucalyptus parramattensis is a tree that typically grows to a height of 15–18 m (49–59 ft) and forms a

capsule 3–5 mm (0.12–0.20 in) long and 5–7 mm (0.20–0.28 in) wide, with the valves protruding above the rim.[2][3][4][5]

Taxonomy

Eucalyptus parramattensis was first formally described in 1913 by

Proceedings of the Linnean Society of New South Wales from material collected by Richard Thomas Baker.[6][7]

Two subspecies and one variety are accepted by the Australian Plant Census:

  • Eucalyptus parramattensis subsp. decadens L.A.S.Johnson & Blaxell[8] is usually a poorly-formed tree with larger leaves, buds and fruit than subspecies parramattensis;[3]
  • Eucalyptus parramattensis E.C.Hall subsp. parramattensis[9] has a conical operculum;[3]
  • Eucalyptus parramattensis var. sphaerocalyx Blakely[10] has a rounded operculum.[3]

Distribution and habitat

Parramatta red gum grows in woodland, on flat and gently sloping country, often in wet sites on sandy soils. Subspecies parramattensis is found to the north-west of

Blue Mountains.[2][3][4]
