I have been deleting a lot of duplicates. So which way do you want to go with many of these, delete the ones with the species names and just leave the cultivar names? Seems that would pop them into alphabetical order that way.
1: Columbine (Aquilegia caerulae 'Spring Magic Blue and White')
2: Columbine (Aquilegia 'Spring Magic Blue and White')
Some have the long species cross, maybe leave the shortened version?
1: Japanese Barberry (Berberis thunbergii f. atropurpurea 'Atropurpurea Nana')
2: Dwarf Redleaf Barberry (Berberis thunbergii 'Atropurpurea Nana')
