Acacia drummondii subsp. affinis (Maslin) Maslin




Occurs from New Norcia S to Bullsbrook East, W.A.


Shrub 0.3–1 m high. Branchlet indumentum variable. Pinnae 2 pairs, 5–10 mm long (proximal pinnae), 5–15 mm long (distal pinnae); pinnules 2–6 pairs (distal pinnae), 3–10 mm long, 1–1.5 mm wide, recurved to revolute, green, densely pubescent or ±sparsely hirsutellous; gland on petiole, absent from rachis. Peduncles puberulous with appressed or patent hairs. Pods sparsely hirsutellous or densely pubescent-villous.


Grows in laterite or sand over laterite, in Jarrah (Eucalyptus marginata), Jarrah-Marri (E. marginata -Corymbia calophylla) and sometimes Wandoo (E. wandoo) forest and woodland.


W.A.: c. 5 km due ENE of Muchea, B.R.Maslin 3218 (BRI, NSW, NY, PERTH); Swan district, E.Pritzel 395 (AD, DBN, E, K, L, LY, M, MO, NSW, P).


The subspecies comprises two variants distinguishable by their indumentum. Some plants from Bindoon–New Norcia area have densely villous-pubescent branchlets, pinnules and pods, peduncles with patent hairs and hairy petals (e.g. R.J.Garraty 153, MEL, PERTH). In the typical variant the branchlets are pilose and puberulous-hirsutellous admixed or occasionally retrorsely appressed-puberulous, the pinnules and pods ±sparsely hirsutellous, the peduncles retrorsely ±appressed-puberulous, and the petals glabrous.
