Adenanthos ×cunninghamii Meisn., in J.G.C.Lehmann, Pl. Preiss. 1: 513 (1845), as A. cunninghamii

T: King George Sound [W.A.], 1836, A.Cunningham ; lecto: G-DC (microfiche seen); isolecto: NY, fide E.C.Nelson, Brunonia 1: 353 (1978).

Illustrations: E.C.Nelson, Brunonia 1: 307, fig. 2r (1978); S.Hopper et al. , W. Australia's Endangered Fl. 34 (1990).

Erect shrub to 2 m tall, sometimes spreading with almost prostrate branches, without lignotuber. Leaves petiolate, 3-segmented, c. 25–30 mm long; laciniae usually 6, sometimes more, linear, flattened, slightly concave, c. 3 mm wide, silver-grey tomentose. Perianth to 30 mm long, dull crimson, with short hairs on outside. Style to 40 mm long, glabrous; ovary glabrous. Fig. 158J–K.

Confined to the Albany district of south-western W.A. where the parent species are sympatric. Map 385.

W.A.: King George Sound, E.C.Nelson ANU 17135, 17143 (CANB, DBN); Salmon Holes, Torndirrup Natl Park, 16 Dec. 1984, P.E.Sanderson, D.Davidson & E.C.Nelson (DBN); Two Peoples Bay, 15 Dec. 1984, P.E.Sanderson, E.C.Nelson & G.Foley (DBN).

A confusing and enigmatic plant which is now considered a hybrid between A. sericeus subsp. sericeus and A. cuneatus . Shrubs are relatively frequent in Torndirrup Natl Park, and occasional at Two Peoples Bay and are especially conspicuous in summer when the young shoots glow coppery red. Plants which are most probably back-crosses with A. cuneatus have recently been discovered around King George Sound. The broad laciniae (to 3 mm) clearly distinguish the hybrid from A. sericeus , as do its crimson flowers.
