      I had these notes related to this subject:

      Native bees were the only recorded pollinators of the rare plant Rudbeckia auriculata at 32 different sites in Alabama, Florida and Georgia (Diamond et al 2006).  The only pollinators of three federally listed plants in Florida (Harperocallis flava, Macbridea alba and Scutellaria floridana) were also native bee species and bumble bees were the only bees observed to come to M. alba (Pitts-Singer et al. 2002).

      Diamond, A. R., D. R. Folkerts, and R. S. Boyd. 2006. Pollination, biology, seed dispersal, and recruitment in Rudbeckia auriculata (Perdue) Kral, a rare southeastern endemic. Castanea 71(3):226-238.

      [Attachment(s) from Riddle,T Charles included below]

      In North Florida and South Georgia Portulaca pilosa and Passiflora incarnata are candidates. The former visited by a medium solid black bee I have yet to catch and is somewhat resistant to glyphosate. The latter visited mostly by the X. virginica. I have seen no honey bees at either one. The color may give some indication why.
