I’m not a plant person, but I believe there are many in iNat who are. The backlog within a given taxon can sometimes be daunting, so those of us who work to eliminate a backlog are often playing catch up, especially with the non ‘sexy’ taxon. As an example, I looked at the eagle category for Canada, and there are 56 pages of unidentified observations. For Noctuid moths, there are over 1,000.
So don’t be disheartened - your observations are still important. There is just a paucity of people who like to identify!!!
