Forms a tree to 12m high. Phyllodes to 14cm long with many, parallel, non-anastomosing nerves are an identifying feature. Produces yellow flower spikes to 7cm long.

"The subspecies is commonly associated with open forests, woodlands, the margins of sub-tropical, closed forest types and along disturbed roadsides. Flowers Jan.-May" (WorldWideWattle, Ver. 2)

Along the Queensland coast, Acacia disparrima blends in with other Acacias having somewhat similar phyllodes. These may include Acacia maidenii, Acacia melanoxylon, Acacia concurrens, Acacia aulococarpa and even Acacia leiocalyx. Attention to presentation of nerves in phyllodes (when fruit not present), the physical appearance of pods and aril colour is necessary to begin seperating these taxa.

In subcoastal southern Queensland we often encounter Acacia disparrima subsp. disparrima around dry rainforest on undulating country with red lateritic soils. On the coast it will grow in various soils including deep sandy loams along beaches in very close proximity to salt water.
