The pignolia nut or seed of the Italian stone pine (Pinus pinea) is. well-known as a food item, especially in Mediterranean cuisine. By contrast, the seed of Pinus sabiniana, a species of pine found only in California and once much utilized by the aboriginal population, is little-known commercially. When examined in terms of nutritional value, shell-to-kernel ratio, and kernel weight, the seeds of these 2 species appear to be similar. It would seem that the difference between them for commercial purposes is the 2000-yr cultivation of P. pinea in Europe as opposed to the general neglect of the California species, at least since the Euro-american domination of the area.
