Prolific identifiers: how do you filter for observations to ID?

I’ve been working on a Yellow Square project that seems to be Poales ID’d as Plants, mostly. I’ve managed to shift about 60% of the observations I’ve reviewed from the hopeless limbo that is “Plants” to the hopeless limbo that is “Grasses.” So many unidentifiable sterile grasses! However, some have gone elsewhere – sedges, rushes, insects, etc. Some of the observations were actually identifiable to genus or species, too.

A whole project of misclassified Begonia? That would be very odd.
