The question was asked if D. virginiana fruit look like tomatoes. As often written beauty is in the eye of the beholder, likewise comparisons. This is a picture of fruit from Killen. To those who think this looks like a tomato, they do.
To answer the question asked what do the seeds look like, see the below.
I personally took the above pictures and freely release them to anyone desiring to use them.
