Geographic locations are given in parentheses for different accessions of Cuscuta gronovii. Although genome size data was unavailable for Cuscuta odorata and C. denticulata, they are close relatives of C. chilensis and C. denticulata respectively and so their published chromosome counts are listed. Standard deviations for all genome size estimates are based on four measurements.
