Edible pine nuts have the following characteristics:

Evergreen trees can grow to 40 meters high, and DBH is 1 meter. The leaves are scaly, triangular, 3-6 cm long, 5- 10 mm wide at the bottom and sharp at the edge. Leaves can grow for 10- 15 years, covering most trees except trunk and old branches.

Dioecious, male and female cones are on different trees. The male cones (pollen) are oval, initially 6 cm long, with a pollen release time of 10- 18 cm and a width of15-25mm. Female cones (seeds) mature in autumn after fertilization 18 months, and are spherical, with a diameter of 18-25 cm, containing 100- 150 seeds and a length of about 5 cm. When the cones are ripe, they are broken and released.
