I use this android app for recognizing plants by picture: http://identify.plantnet-project.org/ http://identify.plantnet-project.org/ It's made by french researchers I think. It doesn't work perfectly but I did identify a lot of plants I don't know with it. You can snap multiple pictures of the same plant, for example, 2 pictures of the leaves, 1 of a flower and 1 of the bark, and then use the combination to search. You can also submit your observations to have them identified by experts.
