Eucalyptus parramattensis

Eucalyptus parramattensis, commonly known as the Parramatta red gum, is a small to medium-sized tree in the family Myrtaceae endemic to a restricted area of the central coast and Cumberland Plain of New South Wales, Australia. It typically grows 8 to 20 metres tall with smooth, mottled grey, white and pinkish bark that is shed in irregular flakes to reveal fresh paler bark beneath. Juvenile leaves are oval to lance-shaped and held opposite for several pairs, while adult leaves are alternate, lance-shaped, 7 to 17 centimetres long and slightly glossy mid-green on both surfaces. Flower buds are borne in axillary clusters of seven on a slender peduncle, each with a conical to beaked operculum, and open to small creamy-white flowers in summer and autumn. The fruit is a small hemispherical to truncate-globose woody capsule with strongly exserted valves. The tree grows on heavy clay alluvial soils in low-lying woodland and is a key habitat species for several threatened plant communities.
