    The text says: ” cones usually-incurved and pointing towards the shoot apex;”.
    Are the cones shown:
    1. Not displaying this characteristic
    2. Being held upside down
    3. I am totally confused?

      Hi Richard – I agree with you; this photo certainly doesn’t show what I’d call “typical” jack pine cones with that curve that the article describes; I do agree with the description. I found another photo at http://www.nhmountainhiking.com/hike/welch/jackpine.html I’ll try to upload it here. It does look more typical I think. I’m not sure if the above photo is the wrong plant, atypical cones, a bad angle or what. -Phil S at Cornell Botanic Gardens

        Thank you, that photo certainly seems to fit the description!

          Richard, I am the photographer of the original picture. My reply is waiting approval but please comment on it! Thanks, Brett

      Hello Everyone, I am the photographer. First let me say that I am not profesional botanist! I volunteer at Uncas Dunes cutting invasive species like Buckthorn and non-native Honeysuckle. I know this area very well and I love it. This particular area (picture) is within the “Sand Dunes State Forest” and which has been planted with trees for a 30-50 years. Thanks for shedding light that it is not what I had labeled it. Please don’t get too upset at person here who lableled it that way. It’s good discussion, I definitley learned something new. I am attaching a picture I just took just last week actually that is in Badoura Jack Pine SNA in Minnesota so hopefully it’s the real deal!

    My father grew up in a log cabin in northern Saskatchewan. He always spoke of the Jack Pine. It shaped his home and his love of trees for all his life.

    The cones in the article’s photo are not typical of any that I have seen, and I’ve been teaching tree & shrub ID for over 35 years here in Thunder Bay, on the north shore of Lake Superior. Sometimes the cones of jack pine point straight out, rather than being curved, but they are usually fairly smooth, looking almost as if they have been dipped in a hard resin. This looks more like a variety of Pinus mugo, mugho pine, which has a more prominent thickening (called an umbo) of the cones scale “apophysis” (that part exposed to the environment before the cone opens to release its seed).

      Thanks for the comment Frances. This maybe not true Pinus banksiana but Pinus mugo, I would disagree, this is a 30′ tree. I am not familiar with hybrids or cultivars of the native tree however.

    Thanks, also, for including the reference to Tom Thompson. That is a painting I admire and have a print of it in my home – captures the northern wilds.
