Well hello,
I must say I was very excited to find this forum & even more excited to become a member:D.
I live on the East coast of Australia & love collecting cacti, my collection has a lot of different kinds of cacti including Mammillaria's & to be honest these are the one I no least about as I obtained most of them a unlabeled gifts. When I meet people & notice they have one little neglected cacti & I start talking about my cacti obsession & they normally end up saying "you can have that one I don't even like it", I guess that there the one losing out;).
My mamms have started flowering over my side of the world & are the first of my cacti to flower, I am hoping to get a few of the identified by you knowledgeable people:D.
Cheers
Taygus
