[408] Some female cones are found at the tips of new shoots. Note that Pinus sylvestri is monoecious, so both male and female cones could be seen on the same tree.

[408_1a] Female cones (red structures above) are found at the tips of new shoots.

[408_1b] Female cones (red structures above) are found at the tips of new shoots. An green immature cone could also be seen above.

[408_2a] Another position of the tree: female cones (red structures above) are found at the tips of new shoots.

The following 3 photos [414, 415, 415_1] were taken from another young plant showing the new shoot.

[408_2b] Another position of the tree: female cones (red structures above) are found at the tips of new shoots.
