Today I bought a Parodia that came from Altman Plants and it doesn't say what species it is. Since it was labeled "Notocactus species" I went to their plant library to see which species they have listed as Notocactus and I have made a list of the species I think it could be.
P. concinna
P. crassigibba
P. herteri
P. horstii
P. mammulosa
P. ottonis
Useless label 🙄
