Acacia verticillata subsp. ruscifolia
(A.Cunn. ex G.Don) CourtSpreading or erect shrub or small tree, 1–10 m high. Phyllodes usually distinctly whorled, linear-lanceolate to ovate, 1–2 cm long, 3–6 mm wide, pungent. Flowers in dense spikes, 2–3 cm long. Flowers Jul.–Dec.
GleP, GipP, OtP, WaP, GGr, WPro, OtR. Also Tas. Apparently restricted in Victoria to Wilsons Promontory and Sunday Island (but see note below).
Plants typically have phyllodes 3–5 mm wide, but sometimes grade to only 2 mm wide. Plants with somewhat intermediate phyllodes have been found in the Otway Range, however, these appear to be better placed in A. verticillata subsp. verticillata due to the absence of plants with broader phyllodes (3–5 mm wide) in this region. While the current distribution is accepted as being near sea-level in south Gippsland only, a couple of specimens from Mt William in the Grampians (alt. c. 1000 m) have phyllodes of similar dimensions. Further investigation is required to establish if these represent the same subspecies, or if the relatively broad phyllodes are a product of the extreme weather experienced on this subalpine mount.
The previous Flora of Victoria account referred to this taxon in a note using the illegitimate name Acacia verticillata var. latifolia Benth.
