The correct spelling for Pinus sylvestris is Scots Pine, the spelling 'scot*h' is (with the single exception for whisky) offensive to people in Scotland and shouldn't be used.
The plant you show as a cedar is actually a juniper (Juniperus), not a cedar (Cedrus) - I've added a pic of a cedar below. Cedars are not very good for christmas trees, as they shed their needles very quickly when they dry out.
The plant you show as a Leyland Cypress is actually a Lawson's Cypress (Chamaecyparis lawsoniana); Leyland Cypress has narrower sprays and larger cones (second pic below)
I considered how to correct the portion on the cedar/juniper, and decided it would be best to just remove it from the article. It is not one of the more commonly used Christmas trees, and I didn't want to leave inaccurate information/pictures in place. I hope this doesn't cause any confusion.
