Acacia fodinalis Pedley, Austrobaileya 5(2): 316 (1999)

Trees to 10 m tall; branchlets reddish, sharply angular, resinous when young. Phyllodes slightly falcate, tapering equally to each end, acute, 8.5–13 cm long, 8–15 mm wide, 7.5–15 times longer than wide, glabrous; longitudinal nerves parallel and crowded (2.5–3.5 per mm), 2 or 3 more prominent than the rest and tending to run together near adaxial margin near base, secondary nerves distinctly anastomosing; gland 0–1 mm above pulvinus, prominent, a distinct swelling of margin with a marked orifice. Inflorescences simple; spikes (25–) 45–70 mm long, rather open; peduncles (5–) 7–10 (–13) mm long, glabrous. Flowers 5-merous; calyx gamosepalous, cupular, glabrous or with a few hairs near the base; ovary hirsute. Pods linear, raised over seeds and slightly constricted between them, to c. 45 mm long, 2.3–3 mm wide, straight, dark brown, marginal nerves yellow. Seeds longitudinal, light brown, c. 3.5 mm long, 1.7–2 mm wide; pleurogram rectangular; funicle folded c. 3 times and thickened into yellow cupular aril.

Occurs in the upper part of the Isaacs R. basin and adjacent part of the Belyando R. basin, Qld, where it usually grows on sandy soils often associated with Eucalytpus crebra .

Acacia fodinalis is closely related to A. leiocalyx but develops into a larger plant with usually narrower and more elongate phyllodes (more than 7.5 times longer than wide), spikes on longer peduncles, and narrower pods. Acacia fodinalis possibly intergrades with A. cretata on the Blackdown Tableland, Qld, fide L.Pedley, Austrobaileya 5: 318 (1999).
