Discussion

Opuntia ellisiana is only known from cultivation in the United States; the type is from a cultivated plant growing in Corpus Christi, Texas.

Opuntia ellisiana has been confused with O. ficus-indica; their fruits are readily separable in the number and distribution of areoles and fruit size.
