As has been noted by others on this forum, certain taxonomic groups are slow to reach Research Grade (that is, to get 2 agreeing IDs to species) because they are difficult groups of organisms to ID from photos and/or there are relatively few individuals on iNat with the knowledge to provide those IDs. Plants, many insects, and I suspect fungi fit those categories. Some won’t be identifiable to the species level.
As I mentioned elsewhere, post a photo-record of a bird and you can often have one or more concurring IDs in about 15 minutes. But don’t wait on your plant records.
