Often, they are simply labeled Opuntia. Youll learn how each of the cactuss leaves, stems, and stalks have evolved to maximize their survival in the desert. In this manner, species of Cylindropuntia can be spread and propagated by passing animals as any of the stem segments will grow into a new plant. There are numerous examples of behavioral adaptation: the reason for this is that most behavior that has the goal of ensuring the survival of a species or just a specific organism can be considered to be a behavioral adaptation. At least 30 or more species have been described for the genus, but this was reduced by Anderson (who followed James Iliff) to just 20 species and in The New Cactus Lexicon the genus was dramatically reduced to just 4 species, one having 4 subspecies for a total of 7 taxa.

Close examination reveals that the flowers actually break through the epidermis of the stem as do any new offsetting stems. The flowers come right out the end of a stem, which terminates the stem growth as a result and a new stem will then branch off the side and grow until it, in turn, results in a flower.

Often, they are simply labeled Opuntia. Youll learn how each of the cactuss leaves, stems, and stalks have evolved to maximize their survival in the desert. In this manner, species of Cylindropuntia can be spread and propagated by passing animals as any of the stem segments will grow into a new plant. There are numerous examples of behavioral adaptation: the reason for this is that most behavior that has the goal of ensuring the survival of a species or just a specific organism can be considered to be a behavioral adaptation. At least 30 or more species have been described for the genus, but this was reduced by Anderson (who followed James Iliff) to just 20 species and in The New Cactus Lexicon the genus was dramatically reduced to just 4 species, one having 4 subspecies for a total of 7 taxa.
