Protocodon

Protocodon robinsiae (synonym Campanula robinsiae) is a rare species of flowering plant in the bellflower family known by the common names Brooksville bellflower, Robins' bellflower, and Chinsegut bellflower.

Today there are two populations in Hernando County and probably three in Hillsborough River State Park.
