Supermarine Type 333
From Tony Buttler’s ‘British Secret Projects, Fighters and Bombers 1935 – 1950 Page 169.
The main difference between the Spitfire wing and the N.8/39 was that the elliptical planform had been discarded in favour of a form incorporating two straight tapers, which approximated very closely to the elliptical form and possessed almost identical aerodynamic properties. The big advantage of the straight taper was that the double curvature was avoided and the covering would require no working.
Why was this planform not adopted for the Spitfire?
