Adenanthos oreophilus E.C.Nelson, Brunonia 1: 367 (1978)

T: East Mount Barren, Fitzgerald River National Park, W.A., 12 Oct. 1972, E.C.Nelson ANU 16948 ; holo: CANB 237037; iso: DBN.

Illustration: E.C.Nelson, Brunonia 1: 307, fig. 2v (1978).

Similar to A. sericeus , but leaves c. 20 mm long, with laciniae 3 or 5 (very rarely more than 5), c. 1 mm diam, appearing terete, but with a channel on upper surface, with appressed hairs, occasionally becoming ±glabrous. Flowers 27–35 mm long, scarlet. Style glabrous; ovary hirsute. Fig. 158F–G.

Occurs in two disjunct mountain regions; the western populations inhabit the slopes of the Barrens, Fitzgerald River Natl Park and adjacent hills, and the eastern populations Mt Ragged and Hill 62, east of Esperance, W.A. Flowers Aug.–Dec. Map 386.

W.A.: Mt Desmond, S of Ravensthorpe, A.S.George 1649 (PERTH); East Mt Barren, E.C.Nelson ANU 1700 3 (CANB, CBG, DBN); Point Anne, Fitzgerald River Natl Park, E.C.Nelson ANU 17041 (CANB, CBG, DBN); summit ridge of Mt Ragged, J.S.Beard 5237 (PERTH); Hill 62, E of Esperance, A.S.George 2157 (PERTH).

Distinguished from A. sericeus by the fewer laciniae, which are also thicker. The two species remain distinct in cultivation. Whereas A. sericeus inhabits sandplain, A. oreophilus is restricted to rocky quartzitic, granitic and lateritic hills.
