Another mammillaria ID

Post by Franj »

Callin CP :D

I've had this plant in the ground now for several years and never knew what it was. Then I picked up a small one with similar spination at Home Depot marked Mammillaria scrippsiana. But Mammillarias.net states M. scrippsiana only gets to be 4 inches across. The one in the ground is at least six.

Needed to bump this back up, it's still not resolved. It has been suggested on another forum that it may be Mammillaria lloydii. Need opinions.

Hi Franj, lloydii is a possibility, and it reaches 6 inches dia. (usually less)... but I'm not sure if lloydii branches dichotomously. When I first saw your pic, my initial thought was something in the karwinskyana group, like ssp. collinsi but there don't appear to be any bristles among the wool, and spines are not quite right.

Hi CP,
I have an M. karwinskiana also and you're right the spination isn't right. As I stated earlier I also have a small one of these, only about 3 inches across, and it's allready splitting. So that seems to be a trait of this cactus whatever it is.
