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.
Eucalyptus cambageana, E. populnea, Corymbia terminalis, Eremophila mitchellii and Geijera parviflora are typical woody species associated with gidgee communities.
Here it is found as a dominant tree with brigalow (Acacia harpophylla), black gidyea (A. argyrodendron), bimble box (Eucalyptus populnea), Dawson River blackbutt (E. cambageana), E. pilligaensis and the smaller trees such as wilga (Geijera parviflora) and false sandalwood (Eremophila mitchellii) in open forest over mainly Cenozoic clay plains.
populnea commonly forms stands with other species such as mulga and Eremophila mitchellii.
