Identification
editIt resembles Opuntia lindheimeri, and immature specimens can be mistaken for that taxon.[3] Mature O. alta plants form discrete trunks and have small fruits. Unlike O. lindheimeri, the flowers have pale stigmas.
Opuntia alta is probably closely related to Opuntia cacanapa, which grows further inland.
