"Acacia coriacea", commonly known as river jam, wirewood, wiry wattle, desert oak, or dogwood, is a tree in the family Fabaceae. It occurs throughout northern Australia, growing as a tall tree on the banks of rivers. It also occurs as a spreading, low tree behind coastal dunes, on spinifex plains and in woodlands in semi-arid regions.

River jam grows to a height of about eight metres. It usually has just one or two main trunks. Like most "Acacia" species, it has phyllodes rather than true leaves. These are thick and leathery, between twenty and thirty centimetres long, and narrow. The flowers are yellow, and held in spherical clusters about five millimetres in diameter. The pods are usually curled up, but are around twenty centimetres long when straightened. They are greatly constricted between the seeds.

Varieties

*"Acacia coriacea" var. "coriacea" is a synonym for "Acacia coriacea" subsp. "coriacea". [ [http://www.anbg.gov.au/cgi-bin/apx?taxon_id=6237 Australian Plant Name Index (APNI)] ]

Subspecies

There are three subspecies:
* Acacia coriacea subsp. coriacea
* Acacia coriacea subsp. pendens
* Acacia coriacea subsp. sericophylla

A. coriacea subsp. "coriacea" is mostly restricted to Western Australia, but there is a small, isolated population in the Northern Territory; "A. c." subsp. "pendens" is endemic to Western Australia. "A. c." subsp. "sericophylla" is the most widely distributed subspecies, occurring in every mainland State except Victoria.
