Sydney green wattle

Acacia parramattensis, the Sydney green wattle, is a fast-growing evergreen tree in the Fabaceae reaching 6–15 m with an erect, slender trunk and a spreading, somewhat open crown. The bark is grey to dark grey-brown, smooth on young trees and becoming finely fissured with age. Young branchlets are angular and finely hairy. Unlike many Australian wattles it retains bipinnate foliage throughout life; leaves are deep green, 5–10 cm long, with 6–15 pairs of pinnae each bearing 15–40 pairs of small, linear-oblong pinnules 3–6 mm long. A prominent gland sits on the petiole and at the junction of each pinna pair. Inflorescences are axillary panicles of small, globular, pale yellow flower heads 4–6 mm across, each composed of numerous tiny five-merous flowers; flowering occurs in summer. The pod is a flat, straight to slightly curved legume 4–10 cm long, dark brown when mature. It is endemic to the Sydney and central tablelands region of New South Wales.
