Eucalyptus conglomerata grows on coastal flats up to 30m above sea level. It occurs mostly in the ecotone between wet heaths (wallum) and tall open forest communities. The soils are infertile, deep and sandy or peaty in texture. Drainage is poor and soils can be seasonally waterlogged. (Halford 1996; DEWHA 2008)


Eucalyptus conglomerata is a mallee or small straggly tree to 12m tall. It has grey to greyish brown, rough, fibrous, stringy bark on the trunk and branches. The juvenile leaves are narrowly lance-shaped, up to 8cm long by 1cm wide, and are rough to the touch. Juvenile leaves are arranged oppositely for a few pairs and then continue in pairs that are not exactly opposite. The glossy, green, adult leaves are broadly lance- or sickle-shaped, measure up to 12cm long by 2.5cm wide and have unequal bases. The adult leaves are arranged alternately along the stems.
The creamy white flowers are grouped into clusters where a leaf joins the stem. Each cluster consists of 13-20 flowers on laterally flattened stalks measuring up to 1cm long. Mature flower buds are egg- or spindle-shaped, measure up to 8mm long, 3mm in diameter and have a cone-shaped cap. The seed capsules occur in crowded clusters and are cup-shaped, 3-6mm long and 3-6mm in diameter. The capsules are slightly constricted at the rim and have 3 enclosed valves. (Brooker & Kleinig 1994; Halford 1996; DEWHA 2008)


Eucalyptus conglomerata has been recorded with flowers from March to June. Flower buds take about 12 months to mature. The seed is held on the tree until the branch on which they are attached dies. (Halford 1996)
