Here is a small Mammillaria species that I picked up at Home Depot today. After searching CactiGuide, Llifle, and other places my best guess is that it may be some variety of Mammillaria perbella. The characteristics that I notice are: globose stem, depressed apex, no wool, approx 20 small white radial spines per areole densely covering the stem, larger single central brown non-hooked spines which all curve upward even from areoles low on the stem.

Mammillaria haageana IMHO

[loyall]

Thanks anttisepp. That is helpful. Mine does look like some photos online of M. haageana elegans. Some photos of elegans show two brown centrals, one downward pointing and one upward pointing. Do you make anything of the fact that mine only has single upward centrals?

Also check against the description of Mammillaria huitzilopochtli v. niduliformis.

loyall,
I have seen specimens for sale under the name Mammillaria pseudoperbella (synonym for M. perbella) that looked exactly like your plant. So, I agree with your initial guess.

Thank you DaveW. That is also a good candidate. M. huitzilopochtli var. niduliformis seem a little less tidy than mine with usually two centrals. Llifle, however, describes M. huitzilopochtli as having 0-1 central like mine.

Thank you Nino_G for that feedback. So perhaps I was correct. I'll just wait to see how it develops and blossoms.

Before wasting a name tag, I would read this 1st:

I agree; viewtopic.php?p=404869#p404869 with anttisepp

Thank you Tom in Tucson. I am not going to waste a name tag. So after linking me to to the Giromagic description of M. perbella you say you agree with anttisepp that it is M. haageana perhaps elegans. I would hope to see some blossoms this spring. That may help.

Seems to fall comfortably within haageana

Thanks MikeInOz. The photos from your haageana forum link seem persuasive.
