showing the tree trunks from the base to the top:
[407]

[406]

[405]

[404] Tree barks on the stem.

[410] Look at the upper trunk. This photo is taken at the lateral branch.

[410_1] The distinctive orange-brown (B) trunk, shed in peeling scales.

[411] Another lateral branch.

----------------------------------------------------------

[190] A lot of male cones. (taken on 11th May)

[400] A lot of male cones at the base of new shoot.

[400_1] Enlarged photo above showing one male cone (strobilus) with microsporophylls.

----------------------------------------------------------

[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.
[414] New shoots developing.

[415] New shoots.

[415_1] Enlarged above to show the tip of new shoot, new needles are emerging from brown leaf sheaths. Female cones may appears at the tip of the new shoot afterwards.

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

[408_3a] Female cones (red structures above) are found at the tips of new shoots. An green immature cone could also be seen above.

[408_4] Yellow male cones and green immature cones could be seen above.

[408_3b] An green immature cone.

[398] A mature (female) cone 3-7 cm, with woody seed scales already opened to release the seeds. The cone scales (seed scales) are not spine-tipped.

The following photos are also different stages of vegetative buds:

[486_1]

[390_1]

[388_2] Vegetative buds and scales on the stem.
