Named for the Tubercles
Mammillaria bocasana ssp. multilanata
This plant is a cactus. It has many spines, some of which look like hairs, some of which look like little hooks. It is globose, and slowly multi-stemmed.
It is in the family Cactaceae, Subfamily Cactoideae, Tribe Cacteae and the genus Mammillaria. The genus was named in 1812 by Adrian Haworth (of Haworthia fame) in 1812, making it an old and stable name. The name Mammillaria comes from the latin word for “nipple,” and is referring to the tubercles, not the round shape of the plant.
