Mammillaria bombycina Quehl, Monatsschr. Kakteenk. 20: 149 149 1910. (syn: Neomammillaria bombycina (Quehl) Britton & Rose);
 


Mammillaria bombycina (silken pincushion cactus) is a species of flowering plant in the family Cactaceae, native to western central Mexico.  

It grows to 20 cm (8 in) tall and spreads indefinitely via offsets. The bulbous tubercles, surrounded by downy white hairs, have short white spines and much longer brown curved spines. Circular clusters of deep pink flowers are borne on the upper surface in spring and summer.[1] 
M. bombycina is one of many Mamillaria species to be cultivated, and is among the easiest.[2] In temperate regions it must be grown under glass with heat, preferably in full sun.

This species is endemic to Mexico, and is known to occur in the states of Aguascalientes and Jalisco (Pilbeam 1999). The area covers around 16 x 10 km. It occurs from 2,340-2,500 m asl. 
It occurs in high mountains, in Quercus forests on steep slopes and grows in leaf-litter and sometimes on inaccesable cliffs (Pilbeam 1999).

Sure looks like Mammillaria bombycina …,

I think the main difference between bombycina and peredelarosae is that peredelarosae has black centrals and bombycina has the cinnamon color spines. These may be more differences, but that is all I have noticed.


Some of the joys of growing cactus as kid were getting cactus spines in my hand. And the ones from this species are back curved which made removing  them quite a bother.


Probably M. bombycina
