Acacia floydii Tindale, Telopea 1: 439; 440, pl. 22 (1980)
Slender shrub or tree to c. 5 m high; juvenile bipinnate foliage often persistent. Branchlets flat or triquetrous at extremities, dark coloured, glabrous. Phyllodes narrowly linear, 7–12 cm long, 1–3 mm wide, slightly uncinate, thin, glabrous, 1-nerved; lateral nerves absent; gland pustulate, prominently exserted beyond margin, 3–15 mm above pulvinus. Inflorescences 8–11-headed racemes; raceme axes 3–6.5 cm long, slender, glabrous; heads globular, loosely 8–12-flowered, cream; peduncles 5–9 mm long, glabrous. Flowers 5-merous; sepals 3/4–united almost to apex. Pods narrowly oblong, to 10 cm long, 8–9 mm wide, coriaceous to thinly coriaceous, dark brown to blackish, glabrous. Seeds longitudinal, oblong-elliptic, c. 6 mm long, slightly shiny, blackish; aril clavate.
Geographically restricted in the Great Divide, E of Tenterfield, north-eastern N.S.W. Grows near rainforest creeks or in moist sand on granite at 900–1100 m alt. in eucalypt forest. The Qld record of this species (as Racosperma floydii ) by L.Pedley, Austrobaileya 2: 348 (1987), was based on a specimen now referred to A. acrionastes .
Closely related to A. acrionastes . Similar to A. perangusta which has shorter phyllodes with smaller glands, smaller flowers on shorter peduncles and pruinose, apparently broader pods. Similar to A. adunca and A. betchei which have golden or bright pale yellow heads often with more flowers, and only slightly prominent or absent glands. Resembling A. macnuttiana in phyllode shape and size.
