Banksia sphaerocarpa var. dolichostyla A.S.George, Nuytsia 3: 422 (1981)

Banksia dolichostyla (A.S.George) K.R.Thiele, in K.R.Thiele & P.Y.Ladiges, Austral. Syst. Bot. 9: 719 (1996). T: just SSE of South Ironcap, E of L. Varley, W.A., 14 March 1978, A.S.George 15106 ; holo: PERTH; iso: CANB, NSW, PERTH.

Listed as 'Vulnerable' in the ANZECC Threatened Flora List 1997.

Thiele (Thiele & Ladiges, 1996) raised this to specific rank on the basis of its larger flowers and old styles that are 'stouter and do not curl around [the infructescence]'. In material that I have seen the old styles curl to varying degrees, sometimes approaching the condition in the other varieties of B. sphaerocarpa . I do not consider this a character strong enough to justify specific rank. The variety is similar to var. caesia in all respects except the larger flower size. I have not seen the material studied by Thiele.
