Jlavipila group (seeCowan & Maslin 1990and Maslin in press)and sccmscloscst to A. loxophy aBenth. which is mosrreadily distinguished by its smallerphyllodcs (3-8 mrn long, 2 5 rnm wide) with resinmasses in their axils,shorter peduncles (2 3 mm long) and fewer flowercd hcnds(20-40 llowcred). There is alsoa relationship,less closely, with another member of the A. flavipila group - A. casslcalaR.S. Cowan & Maslin - which has two mainnerves on eachphyllode facc and a muchmorc regular, imprcssed reticulum; it alsohas glabrous, shorter peduncles(3 5 rnm long in flowor', to I0 mm when in fiuit), smaller, t'ewer-floweredheads (22-30-flowered)and glabrous, narrowcr pods (3-4 rr.rmwide).
