Comments: 12/30/2020,

I'm not sure what this is. It keys to Solidago nemoralis var. decemflora in Ackerfield (2015), but does not look much like photos or voucher images on SEINet. It keys to S. nana in Weber & Wittmann (2012), but also does not look much like photos or voucher images on SEINet. It does seem to fit into Solidago subsect. nemorales per Semple (2018). I suppose it could be a hybrid of some sort. I am open to other suggestions.
