Description

It grows as shrubby plant, with either a spreading or pendant (drooping) habit, from a tree branch or trunk. It has external roots, and hairy new growth maturing to smooth branches and foliage. The leaves are spear- or oval-shaped with a blunt apex, and measure 4–16 cm (1.6–6.4 in) long and 0.6–3 cm (0.2–1.4 in) wide. The inflorescences are composed of 5 to 20 smaller flowers. The flowers are generally yellow or orange with red tips, though some northern populations have redder flowers. They are covered in a fine fur. Flowering is followed by the development of an egg-shaped fruit 1–1.5 cm (0.4–0.6 in) long and red to yellow in colour, which contains a single seed in a sticky coating.

The similar-looking smooth-flowered mistletoe (D. glabrescens) has smooth flowers and leaves broader than 3 cm (1.4 in) in width, and is found west of the Great Dividing Range
