It has fibrous, flaky bark, elliptical leaves, white flowers arranged in small groups on the ends of short side branches, and fruit that falls from the plant when mature.

Aggreflorum ellipticum is a shrub that typically grows to a height of 3 m (9.8 ft) or more with reddish brown, fibrous or flaky bark, the younger stems covered with soft hairs.

The floral cup is densely covered with short, silky hairs, and about 2–3 mm (0.079–0.118 in) long.

Flowering mainly occurs from October to January and the fruit is a capsule about 3–4 mm (0.12–0.16 in) with the remains of the sepals attached, but which fall from the plant when mature.

[1] Aggreflorum ellipticum grows in swampy, coastal heath between Wide Bay in Queensland and Coffs Harbour in New South Wales.
