Acacia scalpelliformis Meisn., in J.G.C.Lehmann, Pl. Preiss . 2: 200 (1848)
Closely allied to A. urophylla but differing principally in the following ways. Phyllodes semitrullate, with a prominent gland angle on the scarcely crenulate adaxial margin 8–11 mm above the base, with base not protracted, 2.5–4 cm long, 6–10 mm wide, pungent, 2-nerved per face; lateral nerves few, not prominent. Pods and seeds not seen.
Occurs at a few disjunct localities in the Pemberton- Manjimup and Augusta districts and near Mt Chudalup, south-western W.A. In the Manjimup area it occurs as scattered individuals in dense populations of A. urophylla ; it seems to prefer damper sites than A. urophylla .
Acacia scalpelliformis is not far removed from the ‘ A. myrtifolia group’ as evidenced especially by its 4-merous flowers, even though it has more than one nerve per phyllode, see J.Vassal, Bull. Soc. Hist. Nat., Toulouse 108: 1–127 (1972). It has been suggested by some field workers that this species might represent a hybrid involving A. divergens and A. urophylla .
