"O. ammophila" was once considered a variety of "O. humifusa"; however, it is a distinct species. Among their many differences, "O. ammophila" has gray-green cladodes rather than green or grass-green. "Opuntia ammophila" can grow to the height of humans, and large plants with thick trunks were encountered 100 years ago. However, now

Along with "O. stricta","O. bentonii" was one of the pest pears of Australia in the early Twentieth Century. Like so many "Opuntia" species, "O. bentonii" has been mistaken for a coastal form of "O. lindheimeri" in Texas, but there are sustained differences. For instance, "O. bentonii" plants are often less than 60 cm in height and the fruit is more globular
