Seedling Identification: Too Early to Tell

After adding compost, a gardener has unknown seedlings with two opposing leaves and a central formation. They want to know what they are.

Expert Advice: The seedlings are dicots (two seed leaves), but true leaves haven't emerged yet. The first leaves (cotyledons) will drop off as true leaves appear. Wait 7-10 days and send another photo. At that stage, identification will be much more reliable.
