ID would be appreciated for these mammillarias
One of my 4 mammillarias is already as "Mammillaria Elongata" (not pictured here) according to guide

Yes it is Mammillaria discolor "Ginza Maru" it matches well with google Thanks!!
Hmmmm other first two showed doesn't match well with cacti pictured on google so "thinking"
Right Mammillaria Karwinskiana yep, at least there's lots of different varieties of same species such as spine length, different areoles, Thanks!
Your suggestion for #1 looks quite likely.
Agree about white spines in mature specimens and also in karwinskiana ssp.nejapensis. Spines on younger ones usually have brownish tips. white hairs also better develop in older karwinskiana plants imho.
...I wouldn't call #2 a pringlei. I know a couple of such plants, their spines are a lot thinner, longer and slightly curved.fragrancecactii wrote: ↑Fri May 03, 2024 7:10 pm hmmmm second one is probably going be hard without flower which sadly there's no currently buds on this plant but yes second one looks much closer to Mammillaria pringlei
Thanks! It could be columbiana!, All previous species mentioned previously by others are wrong due to wrong color of flower (pringlei and nivosa are red and white flowered species but one columbiana is pink flowered species!)
