Elaeocarpus reticulatus is a shrub or small tree that typically grows to a height of 3–10 m (9.8–32.8 ft), but up to 30 m (98 ft) in some situations, and has a lignotuber at its base. The leaves are simple, (strictly compound with only one leaflet), oblong to elliptic, mostly 50–130 mm (2.0–5.1 in) long and 10–40 mm (0.39–1.57 in ...

Leaves show a characteristic curling, similar to damage caused by viruses. Heavily infested plants have shortened internodes leading to resetting or a "bunchy top" appearance. A heavy, black, sooty mold may develop on an infested plant's leaves and stems as a result of the mealybug's heavy honey-dew secretions.
The blue quandong begins to flower around the seventh year, [4] and the inflorescences are racemes up to 10 cm (3.9 in) long, produced in the leaf axils and on the branches below the leaves. [ 5 ] [ 9 ] They each bear 12–16 fragrant, pale green to white flowers on pedicels about 15 mm (0.6 in) long.
The tree is the sole source of food for the catalpa sphinx moth (Ceratomia catalpae), the leaves being eaten by the caterpillars. When caterpillars are numerous, infested trees may be completely defoliated. Defoliated catalpas produce new leaves readily, but with multiple generations occurring, new foliage may be consumed by subsequent broods.
The understory is the underlying layer of vegetation in a forest or wooded area, especially the trees and shrubs growing between the forest canopy and the forest floor. Plants in the understory comprise an assortment of seedlings and saplings of canopy trees together with specialist understory shrubs and herbs.
A large tree, near Waroona. Banksia ilicifolia is a variable species. It usually grows as an erect tree up to 10 metres (33 ft) in height, but some populations along the south coast consist of small trees or even spreading shrubs. [3] It is generally a 5 metres (16 ft) high small tree in the Margaret River region. [4]
Every species in the genus is an evergreen, and the leaves vary in size from minute and scale-like (M. micromera) to 270 mm (11 in) long (M. leucadendra). Most have distinct oil glands dotted in the leaves, making the leaves aromatic, especially when crushed. [2]: 20–21 Melaleuca flowers are usually arranged in spikes or heads.
