Acacia rhodoxylon Maiden

Common Name

Rosewood, Ringy Rosewood




Occurs in coastal and subcoastal parts of central Qld, from near Eidsvold N to SE of Mount Garnett.


Tree 6–20 m high. Bark peeling in small curved flakes similar to ‘Minni Ritchi’ species. Branchlets glabrous, resinous. Phyllodes narrowly elliptic to ±oblanceolate, commonly inequilateral with a ±straight lower margin and convex upper margin, straight or falcate, (4–) 6–10 (–13.5) cm long, 8–20 (–25) mm wide, coriaceous, glabrous, resinous when young, with numerous indistinct close non-anastomosing nerves, of which 3–5 slightly more prominent. Inflorescences simple, 1 or 2 at base of rudimentary axillary shoot; peduncles 8–20 mm long, glabrous; spikes 2–3 cm long. Flowers 5-merous; sepals united into a ±truncate calyx. Pods narrowly oblong, 3–7 cm long, 5–9 mm wide, thinly coriaceous-crustaceous, glabrous, slightly resinous. Seeds longitudinal to oblique, widely elliptic, 3.5–4.5 mm long, shiny, brown; aril small.


Grows in woodland, eucalypt woodland or eucalypt forest.


Qld: 45.4 km from Capella towards Clermont, N.Hall H78/66 (NSW, PERTH); c. 72 km SE of Mount Garnet, S.A.Morain 9 (BRI n.v.); 20 km NE of Eidsvold, L.Pedley 4016 (BRI), Goodnight Scrub State Forest, SW of Bundaberg, M.B.Thomas 262 (BRI); Collinsville Coal Company lease area, Collinsville, H.Thompson AQ395239 (BRI, MEL n.v.).


Hybridises with A. shirleyi in places in east-central Qld, e.g. 125 km SSE of Charters Towers, R.J.Cumming 11579 (PERTH).

The extreme range of variation in phyllode shape and size, and in pod dimensions, could be related to the age of the plant.
