This plant is almost certainly a hybrid, though the parentage is unclear, rather than a sport from a straight up species. It has never been observed in the wild, making its origins very unclear. On another site devoted to Agaves someone has recently posted some not very clear pictures of a 'Kichijokan' in flower. The inflorescence strongly suggests a hybrid origin and certainly does not look like an A. potatorum inflorescence. Many experts suspect that Agave isthmensis is a more likely potential parent.
Many of the other plants the Baja references to above are specific selections of sports from the original 'Kichijokan' or 'Kissho Kan' that have been put into production via tissue culture, they are mostly not new hybrids or new heretofore unidentified species. So right now they should be considered as cultivars rather than new species. PDN while a great nursery does tend to bring out a lot of plants with fancy names, that when looked at in detail can often be identified as specific selections from already well known and named species. Nothing wrong with that as it clearly serves a significant number of Agave collectors/growers, but some of these cultivars have started making appearances as new species on other websites, causing significant confusion, because PDN is not always very clear in what exactly a newly named plant listed on their website represents.
To me, all these slightly different but mostly the same plants are just that variations on the same thing, but I know plenty of growers for whom even small differences in for example variegation patterns makes it worth having that plant even if they already have several of the same species with slightly different variegation, and without a strong guarantee that the variegation will remain stable. So naming them helps get these plants sold.
