Winter botany quiz #3

I won’t be coy about the location of these trees, all of which were photographed within the Lake Tahoe Basin during my recent trip. A further clue: I have already alluded to these species in a previous post. Once again, comment moderation has been turned on to give everyone a fair shot, and I’ll let the quiz go for a couple days or so. I think this quiz will be easier for my North American readers than Winter botany quiz #2, but maybe still harder than Winter botany quiz #1. Anyone who can correctly identify all six species wins my undying admiration 😉

EDIT: Pedant that I am, attention to nomenclature will serve as a tie-breaker if needed.

  1. #1 Ponderosa Pine
    #2 Jeffrey’s Pine
    #3 Lodgepole Pine
    #4 Sugar Pine
    #5 Western White Pine
    #6 Bristlecone Pine

    Many of these are the source of fond memories of backpacking in the Sierras.

  2. Ted- These are beautiful specimens. It has been a while since I studied western conifers, so I’m going to appreciate their botanical beauty and not wager any guesses.

  3. Best guess effort on some of these, but here goes:
    #1 Jeffery pine Pinus jeffreyi
    #2 Coulter pine – Pinus coulter
    #3 Lodgepole pine – Pinus contorta
    #4 Western white pine – Pinus monticola
    #5 Sugar pine – Pinus lambertiana
    #6 The Larch – Larix decidua monty pythoni

    Honestly no idea what #6 is

  4. Congratulations to DougT, who nailed all but the last one! #6 is whitebark pine, Pinus albicaulis (bristlecone pine was a good guess, though).

    Nice attempt by dtsh, who came up with four correct names (only one of them was associated with the right picture, but it was a nice try). He does get extra credit for including both the scientific name and common name in each of his answers.

    I’ll have more about these species in a forthcoming post.

    Thanks for playing everyone!
