Well I have raised all 3 families of peppers, Annum, Frutescens, and Chinese and I don't think that I have ever seen where you can differentiate by the flowers. I don't think I have ever read that you could either now that I think about it.
We have over 600 flower images in the database, try searching using the species dropdown and you will see the differences. Pubescens are beautiful and some of the wild species like cardensaii and eximium are also stunning.
