This carmenae variety of mammolaria has similarities to the traditional albiflora, and also produces delicate white flowers when grown in proper conditions. The spines provide greater coverage of the cactus and these seem to like a little more light and heat than the traditional albifloras.
This is another great, small and compact, flowering cactus that is great for any plant collector.
