Some Mammillarias for ID:

Hello everyone!  

I'm doubtful with some mammillarias...


1) 8-9 radial white spines, 1-2 central black spine... Probably MAMMILLARIA MELANOCENTRA or WAGNERIANA?




2) 17 beige radial spines, 4 central spines (the bottom is longer and dark)... Maybe MAMMILLARIA DISCOLOR/CV. GINSA-MARU?




3) 9 white radial spines, 1 central... MAMMILLARIA VOBURNENSIS EICHLAMII?




4) 17 radial crystal white spines, 4-5 yellow central spines (the bottom is longer and uncinate)... MAMMILLARIA MAGNIFICA?




Thanks!!!

Another suggestion for #1 could be Mammillaria wagneriana
# 2 ginsa-maru
# 4 could be Mammillaria rhodantha ssp. pringlei

When i researched the description of Mammillaria Wagneriana and Mammillaria Melanocentra, note that resembled more a Wagneriana, although i sold the plant as Mammillaria Melanocentra Rubrograndis

In the case of the Mammillaria Magnifica seems, not Mammillaria Rhodantha Pringlei.
