Callicoma serratifolia

A tree, often seen as a large shrub, potentially growing up to 20 metres in height with a 5-metre spread, sometimes multi-stemmed.

It grows naturally in New South Wales and Queensland, in near-coastal areas, as far south as Batemans Bay, and as far west as Lithgow, extending up the coast and tableland-fringes, as far north as Kroombit Tops National Park in Queensland (east of Biloela). 

It is found in temperate rainforest, wet sclerophyll forest as well as gully creeklines in areas such as Hawkesbury Sandstone dry sclerophyll forest. It can dominate creeklines in some cases (sometimes further up sandstone gullies). Around Sydney, it is typically found on sandstone and enriched-soil creeklines. 

This is the only species of the genus and it has simple and opposite leaves (a lot of other members of this family have opposite leaves but often compound).  Leaves are lanceolate to elliptic, up to 12 cm long and 5 cm wide with coarsely serrate margins (hence the very apt species name), with dark green upper sides and white and hairy undersides.  

Flowers are arranged in globular heads, with flowers have 4 or 5 sepals and no petals with numerous stamens. The heads do resemble those of wattles, being pale yellow and with staminate flowers. The heads appear in late spring and summer and average 1.5 cm in diameter and have stalks 1 to 2 cm long. 

The fruit is a capsule, which split when ripe to release the seeds.
