mid-stem leaves in comparison photo: S. flexicaulis (L), hybrid (centre), S. caesia (R). Lower stem leaves of hybrid were broader, with obvious lateral veins (see e.g., plant at bottom left of photo 1)

I found this rare liverwort and had it identified by Terry Taylor. See the entry on the ecoreserves website at https://ecoreserves.bc.ca/2011/10/07/riccia-frostii-a-new-find-on-the-sandbars-of-the-fraser-river-islands/

by far the largest Black Walnut I've seen in eastern Ontario; I think this is likely an "original forest" tree. On the Little's range map, note the green dot near Prescott which matches up well with Black Walnuts in this area being potentially wild/indigenous:

With a large, apparently wild Bitternut Hickory beside it.

The observed plant appears to be a goldenrod. It was growing within a dense colony of Solidago ptarmicoides (Oligoneuron album), a plant very common at this location. The plant was the same height as O. album and stood out only because of the flower color. I was unable to find any morphological differences between the stem and leaves of the observed plant and three typical neighbouring plants of O. album. My best guess is that it is either an aberrant form of or a hybrid of O. album. This taxon is known to form hybrids with other Oligoneuron species but none of these occur at this location. Perhaps someone with a deeper knowledge of goldenrods can provide some insight.
