Description
This plant is an extreme form of this very variable rich in forms species, but it is not justified the attribution of the rank of variety.The plants that are today in cultivation with the name “Major” are plants with high homozygosis levels derived from the first selected specimens originally used to describe the new form. This plants was at first multiplied asexually or by controlled pollination, so they remained - generations by generation - almost unchanged in appearance. So the initial extreme types with the long strongly open cluster of spines involuntary began in the course of time to be cultivated and is now in our collections as good form. A whole series of such "European” form and variety of cacti is now recognized, however in nature plants shows - in the same place too - all their intermediate forms and passages and grow one to each other.
