Discussion

Cuscuta boldinghii was reported from Florida as a parasite of Citrus (L. C. Knorr 1949); it was collected again in Florida (Monroe County) in 2002.

Cuscuta boldinghii and C. erosa are the only species in the flora area bearing hornlike appendages with sto­mata on corolla lobes (M. Costea et al. 2011).
