Acacia ramulosa W.Fitzg. var. ramulosa




Occurs throughout the range of the species.


Phyllodes thick, subterete to flat, 7–15 (–18.5) cm long, 1.4–3.5 (–5.5) mm wide. Spikes 5–25 mm long. Corolla 1.5–2.5 mm long, with long hyaline hairs on lobes, sometimes confined to margins. Seeds to 12 mm long and 9 mm wide, though over much of the range of the species to 7 mm long and 5 mm wide.


Flowering Mar.–Sept.; fruiting Sept.–Nov. (a single record in March).


W.A.: 10 miles [16 km] from Hamelin, C.H.Gittins 1529 (BRI, NSW, PERTH). N.T.: 6.5 km SW of Wallara Ranch, J.R.Maconochie 1795 (BRI, DNA, PERTH). S.A.: Olympic Dam, F.J.Badman 2018 (AD, BRI). Qld: c. 45 km WSW of Winton, L.Pedley 5298 (BRI). N.S.W.: Homestead Ck, Mootawingie Natl Park, 17 Sept. 1990, G.J.White s.n. (BRI, CANB, MEL, NSW).


Superficially similar to A. effusifolia.

Plants in the extreme west of the species’ range on the Peron Peninsula and perhaps the eastern shore of Shark Bay have phyllodes 3–5.5 mm wide, flowers a little larger than is usual for the species over the rest of its range and massive seeds similar in shape to those of Acacia farnesiana, 11–12 mm long and up to 9 mm wide. One of the paralectotypes of A. cibaria (Gasgoyne R., [W.A.] O.Jones s.n., MEL) probably belongs here.
