Acacia trachyphloia Tindale, Proc. Linn. Soc. New South Wales ser. 2, 85: 248 (1960)

Golden Feather Wattle , Bodalla Wattle

Erect shrub or tree 4–15 (–18) m high. Bark grey, smooth, later rough and corrugated. Branchlets terete or slightly angled, white- to golden-villous; ridges c. 0.2 mm high. Young foliage-tips golden, velvety. Leaves herbaceous, soft, greenish grey to dark green; petiole above pulvinus 0.1–0.5 cm long, terete, eglandular; rachis 2–11 cm long, terete, with globose, villous glands at base of upper 2–10 pairs of pinnae; pinnae (6–) 9–25 pairs, (0.5–) 1–4 cm long, lower pinnae shorter than others; pinnules (8–) 16–40 pairs, narrowly oblong or oblong-elliptic, 1–2.5 (–3) mm long, 0.4–0.6 (–0.8) mm wide, with 1 submedian vein, clothed especially above with golden or white or subglabrous, loosely appressed hairs, apex acute or obtuse. Inflorescences in axillary racemes, or terminal or axillary false-panicles. Heads 10–20-flowered, pale to deep yellow. Pods submoniliform, 2–7.5 cm long, 4–8 mm wide, subcoriaceous, dark blue or brownish black, often slightly pruinose. 2 n = 26, B.G.Briggs, on E.F.Constable 6927 (NSW) & 6928 (NSW).

Occurs on the South Coast and Southern Tablelands, N.S.W., from Conjola to Broulee Beach, W to Braidwood and Monga. Grows in moist gullies, on alluvial flats or mountainsides, often near creeks, in open or tall open forest, mostly in heavy soils. Flowers Aug.–Oct.; fruits Dec.–early Mar.

This species is most closely allied to A. oshanesii but the lower surface of the pinnules is very much paler than the upper in the latter species, also the general vestiture is fawn instead of golden. Both species are characterised by pendulous branchlets and few glands restricted to bases of the upper pairs of pinnae, interjugary glands being absent.
