Acacia fasciculifera F.Muell. ex Benth., Fl. Austral. 2: 361 (1864)

Scrub Ironbark , Rosewood (Moreton district)

Tree usually to c. 10 m high; canopy dense. Branchlets pendulous, slightly flexuose, normally glabrous. Phyllodes narrowly oblong to narrowly elliptic, 4–15 cm long, 7–20 mm wide, sometimes 35 mm wide (especially young plants), somewhat coriaceous, normally glabrous; midrib and marginal nerves prominent; lateral nerves rather obscure and openly anastomosing; gland 0–10 mm above pulvinus, circular to oblong, 0.5–0.7 mm long. Inflorescences 2–8-headed racemes, often appearing as axillary clusters; raceme axes 1–3 ( - 15) mm long, puberulous; peduncles 1–2 cm long, glabrous or sparsely puberulous; heads globular, 20–40-flowered, cream. Flowers 5-merous; sepals free. Pods to 12.5 cm long, usually 10–13 mm wide, thinly coriaceous; marginal nerve prominent. Seeds ±longitudinal, oblong to orbicular, flat, usually 6–7 mm long, slightly shiny, dark brown; funicle thick, scarcely arillate.

Occurs mainly from near Boonah N to near Rockhampton, Qld, with a few scattered occurrences further N to near Bowen. Grows in open Eucalyptus forest on ridges or along creeks, or with A. harpophylla . Usually summer flowering.

Some specimens from the Port Curtis and North Kennedy Districts (e.g. B.Hyland 6054 , BRI, NSW; E.Zillman 9 , BRI) have consistently short phyllodes (4–8 cm long), broad pods (2 cm wide) and large seeds (15 ´ 9 mm). Elsewhere the phyllodes all or mostly exceed 7 cm long, the pods narrower and seeds smaller. According to L. Pedley, Austrobaileya 1: 263 (l980), the pods are sometimes only 8 mm wide with seeds 5 ´ 4 mm.

Acacia fasciculifera normally grows to c. 10 m high, however, it can reach 20 m or more with the trunk reaching 0.6 m diam. It is sometimes logged for timber. Its flowers are sweetly perfumed but the smell is different from the normal wattle scent, fide B.A.Lebler, Wildfl. SE Queensland 2: 46 (1981).

Sometimes superficially resembling A. crombiei . The pods and seeds described by G.Bentham, Fl. Austral. 2: 362 (1864) under A. macradenia are those of A. fasciculifera , fide F.J.H. von Mueller, S. Sci. Rec. 2 (7): 150 (1882).
