It has smooth bark, linear to lance-shaped leaves, white flowers and usually grows along creeks, often in water.

Aggreflorum brachyandrum is a shrub or small tree that typically grows to a height of 4–6 m (13–20 ft) and has smooth bark that is shed in strips.

[2][3][4] This tea-tree was first formally described in 1919 by Ferdinand von Mueller who gave it the name Kunzea brachyandra and published the description in his Fragmenta phytographiae Australiae.

[1] The specific epithet (brachyandrum) is derived from ancient Greek words meaning "short" and "male", referring to the stamens which are shorter than those of kunzeas.

It is found in coastal and near-coastal areas from North Queensland to Port Macquarie in northern New South Wales.
