MS in biology from University of Colorado Denver and Natural History Collections Assistant at Denver Botanic Gardens.
I mostly ID for the Denver Ecoflora Project and my primary source for identification is "Flora of Colorado" (Ackerfield 2015).
I use SEINet (https://swbiodiversity.org/seinet/) when I have questions about species' distributions and to compare iNat observations against specimens in the Kathryn Kalmbach Herbarium. Kew's Plants of the World (http://www.plantsoftheworldonline.org/) is where I go for taxonomy questions.
IDing plants from pictures is hard and I make mistakes all the time. Please correct me if you think I've misidentified something!
