To ID a conifer

Some trees are really obvious and easy to ID but, to make ID easier, my habit is to include photos of:

  • the whole plant to show overall form/stature,
  • a very closeup of leaves,
    on big trees when I can not get close to leaves, I might use a telephoto to get the best view possible.
    In pines, looking for number of needles per fascicle and needle length; in the cypress family, juniper in
    particular, looking for scale leaf overlap, tip shape and leaf gland visible or not.

  • close up of seed cones (in pines, what looks like miniature cones are likely pollen cones; in junipers, tear
    open a fleshy seed cone to check seed(s) size and shape.
    Notice if both pollen and seed cones (monoecious) or only one or the other (dioecios)

  • a portrait, so to speak, of mature bark.
