Acacia argyrodendron, known colloquially as black gidyea or blackwood,[2] is a species of flowering plant in the family Fabaceae and is endemic to Queensland.

Acacia argyrodendron is a tree that typically grows to 8–25 m (26–82 ft) and has furrowed, dark grey to black bark.

The type collection was made by a Czech geologist, Jeri [George] Vaclav Danes, who travelled between Aramac and Pentland, where he reported open forest consisting mostly of so-called brigalow (black gidya).

[4] Acacia argyrodendron is found in central Queensland in the basins of the Cape, Suttor and Belyando Rivers on clay soils in areas where the annual rainfall ranges between 475 and 655 mm (18.7 and 25.8 in).

Associated understory plants include shrub species such as the false sandalwood (Eremophila mitchellii), yellow-wood (Terminalia oblongata) and conkerberry (Carissa spinarum), and smaller herbaceous plants such as brigalow grass (Paspalidium caespitosum), yakka grass (Sporobolus caroli), blue trumpet (Brunoniella australis) and Dipteracanthus australasicus.
