Hi Jim,
Thank you for the question. That was a good one.
The f. in scientific name of “Cornus florida f. rubra” means form (forma in latin). In botanical nomenclature, a form (forma, plural formae) is one of the “secondary” taxonomic ranks, below the variety, which in turn is below the species.
I’m not an expert in botanic names, but for reference, please visit: https://en.wikipedia.org/wiki/Form_(botany)
