    • @jim-barkley This might be a series of suggested taxa so there might be several posts. The lighter leaf (edges of picture) could be Winteraceae or Berberaceae.

    • MacKenzie I think the lighter one is Allophylus flexifolia. The darker one is the question mark. Also, I didn’t know how to handle two specimens on a single plate. The database is a little restrictive.

    • Hi @jim-barkley! I certainly see the overall shape and asymmetrical base as being similar to Allophylus. However, the secondary veins of Allophyllus are crasspidodromous meaning that they go directly to the margin. The veins on this leaf bifurcate before they get to the margin. There are also several intersecondaries which is something I don’t see when looking at the modern Allophylus. But I do thing that is a good observation that this is coming from a plant that has likely has compound leaves and not simple ones (denoted by the asymmetrical base). I’ll keep that in mind with my search.

      In terms of uploading this as two separate entries what we recommend doing is having the primary photo to be the leaf you want (leave Leaf? the other one out of the shot) the and then additional photos can be the shale plate as a whole. Then, do the same thing with the other leaf. Thanks! Great specimen!

    • Thank-you, Mackenzie. I will re-shoot this and try again.

    • @mackenzie-smith were you able to narrow down the ID on this one?

    • @vperez and @jim-barkley I can’t see the venation on the dark one. It’s too dark. The overall shape looks Salix like (willow). Salix has been described from the GRF in 1934 by Brown. This image is just for the darker one. The lighter one has it’s own specimen number and image.

    • MacKenzie Smith I added some pics that show a little venation as well as a Salix that should illustrate the differences. Thanks for looking.
