When you propose the addition of a new plant, you have to wait for the proposal to be appproved. In this case, you proposed the addition of Ranunculus acris, but it's already in the database, so I declined your proposal and sent you a link to the entry.
This is the link I sent you:
Meadow Buttercup (Ranunculus acris)
Open the link and scroll down below the plant data and the photos that are already there. Click on "Upload a photo."
