2 doubts mammis:

Hello!

I have doubts about these mammis that do not know their names.


- Two central spines, the lower one is longer than the upper, 25 thin radial spines and white... Possible Mammillaria Parkinsonii?





- This one has 4, 5 and 6 radial spines the lower one is longer than the rest, it has no central spine, the epidermis is bright green and has axillary wool. The question is, how to differentiate whether it is a Mammillaria Karwinskiana or a Mammillaria Knippeliana??? Are the same, what do you think? (I suppose it is more likely to be the typical Mammillaria Karwinskiana Nejapensis)






Thanks friends!!!

I'd say that you are quite right with M. karwinskiana, and I think it is just that, not one of the subspecies. Your suggestion of M. parkinsonii also seems to be a good bet, though I think it needs to be a bit older to be sure.
