The seeds are large and heavy, 10 mm long and 8 mm broad, with a short rounded wing 13 mm long; [4] they may be bird or mammal dispersed as the wing is too small to be effective for wind dispersal. Trees start producing seeds at about 20 years of age.
The seeds (pine nuts, piñones, pinhões, pinoli, or pignons) are large, 2 cm (3 ⁄ 4 in) long, and pale brown with a powdery black coating that rubs off easily, and have a rudimentary 4–8 mm (5 ⁄ 32 – 5 ⁄ 16 in) wing that falls off very easily.
