    @megnd well here's our targets
    I feel confident identifying Solidago ptarmicoides, Solidago rigida, Euthamia graminifolia but that still leaves a lot of unknowns on the table

    i see ND has eleven species...MB has 15 and SK has 12

    You are tremendously brave to tackle the Solidago! :) I love these plants, but the ID's and keys are -- nightmare fuel! ;)

    I can Identify rigida

    I have started a key for goldenrods about 7 times so far. It is a case of the more you learn, the more you need to learn. I am trying to come up with a more visual, less technical key for Ids of photos of goldenrods. Something to do this winter. 🤔😣🤩

    @e16 i think i am thinking that to start with what images to include in the observation to help identifiers - and identifying what key features identifiers are using (or could be using) to clinch an id

    1 - Location

    2 - Time of year

    then:
    For every plant clear and up close pictures of the following are preferred
    Leaf front and back
    Leaf attachment
    Stem up close
    Base of stem (at soil)
    Inflorescence
    Flowers
    Other close-ups that can help. Bugs and galls on the plant, diseases, roots, Other?

    also a wide shot of the plant in place

    Look for leaf type (compound, simple. etc), attachment (opposite-alternate)(sessile, clasping, etc.), Vein pattern, Margin
    Hair- stem (pubescent, sparse, absent, inrows, etc), leaf front and back (pubescent, hair in rows, hair on veins, hair on margins, etc)
    Overall shape, height and habit of stem and flowers.

    From this, Identifying the subsection is an accomplishment. I get stuck with the wide variability within a species that often prevents getting to the subsection. I don't currently know how many keys must be confirmed to positively ID all goldenrods. Somebody has probably already done the stats of that.

    [My guess is 6 keys because as we all know, 7 keys always ends with Kevin Bacon. (That's a joke) 😁]

    @lysandra has been very helpful with plants in this region.

    spent some time filling in 'flowering' phenology across the three focus areas (MB/SK/ND) - still aways to go to catchup with the back log :)

    Thanks for looking at this! I will start using Triplinerviae to identify unidentifiable 'Solidago canadensis' photos. This is a difficult group to aid with on iNat.
