Pest status
Gossia gonoclada is a tree 3-12m high with a dense canopy of glossy, deep green foliage. The new leaves have a pink flush and the bark is pale red-brown in colour and is either flaky or scaly. The most distinctive characteristics of this species are the four raised corners on the angled branchlets and the unique scent of the leaves when crushed.
The flowers are white with 4-5 smooth petals, are 6-9mm in diameter, and occur singly at the base of the leaves. The fruit is a globular, glossy, soft fleshed black berry 7-12mm in diameter.
The winged branchlets, slightly retuse leaf apex, and 5-merous flowers distinguish G. gonoclada from similar species in the area. (A. gonoclada Recovery Team 2001; Snow & Guymer 2003; DEWHA 2008)
View Map
Gossia gonoclada is currently known from sites along the lower reaches of the Brisbane and Logan Rivers and their tributaries. Specimens from the 1860s were also collected from Moggill, southeast Queensland. (A. gonoclada Recovery Team 2001; Herbrecs 2008)

Range derivation
Range derived from extent of the taxon's verified records
Gossia gonoclada is found in lowland riparian rainforest and notophyll vine forest, along permanent watercourses subject to tidal influence. It usually grows below the peak flood level, on steep slopes and at low elevations of 5-50m. It occurs on moderately well drained clay soils, sandy loams and alluvial soils. (A. gonoclada Recovery Team 2001)
Gossia gonoclada flowers are likely to be pollinated by native bees. As the seeds are located within a sweet, soft and fleshy fruit, it is suspected that they are dispersed by animals, particularly birds and bats. Other animals such as lizards and small mammals may play a role in seed dispersal. (A. gonoclada Recovery Team 2001)
Gossia gonoclada reproduces both vegetatively (from stem suckers following damage to the main stem) and from seed. Seed germination occurs in 8-60 days and nursery-grown seedlings can reach a height of 30cm in 12 months. It is not known at what age or size the tree reaches maturity. Buds and flowers appear in late spring (October to November) with the fruits ripening from mid-January to February. The fruits remain viable for only a short period and the quantity and viability of the fruit produced varies markedly from year to year. (A. gonoclada Recovery Team 2001)
