Thanks. All the Mediterranean pines are in the section Pinaster . Roxburghii too, but it's leaves are obviously too long. Halepensis is the only one I have access to with relatively short needles and doesn't throw back to juvenile needles.P. canariensis is actually most closely related to Pinus Roxburghii, a pine tree species from the Himalayas.
Not so much with the other Mediterranean pine trees, Pinus pinea being accepted as the closest.
