Scientific Name: Mammillaria Bocasana cv. Fred
Synonyms: Mammillaria bocasana f. monstruosa
Origin and Habitat: Nursery produced cultivar, it was cut off and started on it's own
USDA Hardiness zone: 10a to 11b [ -1.1 °C to +10 °C ]
Size: Vary, according to time of year
Form: Massive clusteres. Some reverts back to original cactus shape.
Spines/hair: None/rarely
Flower: Whiteish
Flowering: Rarely
Growth rate: Up to 1.3 cm in winter, and twice that size in summer
Light: Hates the full sun in summer. Protect from frosts and freezes.
Propagation: "It can thrive for years, but tend to self destruct, especially when it really odd looking. As with most Freds, it began to die at the base (root rot is common); instead of giving up on it, you can cut it apart, let it heal and start many plants from that one... The best luck is with cuttings that are 3 cm or larger; smaller ones will root, but it takes much more effort to keep them alive."

Mammillaria lasiacantha subs. egregia (Backeb. ex Rogoz. & Appenz.) D.R.Hunt
Mammillaria stella-de-tacubaya Heese
> Mammillaria chica Repp.
Mammillaria gasseriana Boed.
> Mammillaria viescensis Rogoz. & Appenz.
"There is a lot a confusion about Mammillaria stella-de-tacubaya and Mammillaria gasseriana (comprising Mammillaria chica and Mammillaria viescensis), if the plant has separated clusters of radial spines and a single strong hooked central it should be stella-de-tacubaya, and if the radial spines are fine and overlapping, and the central slender and long, then its proper name should be gasseriana."
