This is an interesting dilemma. We have so many cultivar entries with A. andraeanum as their species name, in addition to the A. andraeanum species entry. Unless those cultivars are a cross of andraeanum with andraeanum, the species will have to be deleted from the entry names.

I'm interested in hearing what
@eclayne sees as the best solution. I don't think we can have an entry called Anthurium x cultorum because I don't see it listed as a valid species name in any taxonomic database.
