Article summary

Editorial SEO summary

The 1853 publication, broad species circumscription, 38 synonyms, north-eastern Mexico to Jalisco range, and LC status of Mammillaria bocasana.

Scientific taxonomy article

Accepted name and original publication

The accepted name is Mammillaria bocasana Poselg. Heinrich Poselger published it in 1853 in Allgemeine Gartenzeitung 21: 94.12 Kew and World Flora Online accept the species, so historical combinations in Cactus, Chilita, Ebnerella, Krainzia, and Neomammillaria are not current canonical names.13

Taxon boundary and extensive synonymy

Kew's 2026 backbone lists five homotypic and thirty-three heterotypic names, for a total of 38 synonyms.1 This unusually long list reflects the consolidation of hairy, long-spined, and geographically named forms under a broad concept of M. bocasana. An old subspecies or variety name in the synonymy does not justify assigning that infraspecific name automatically to a commercial specimen.

Taxonomic assessment considers the globose to short-cylindrical stem, dense white hair-like radial spines, and one or more hooked central spines together. Hair density, spine colour, and flower colour can vary with genotype and growing conditions; no single variable feature is sufficient to assign an infraspecific name.

Systematic position

In the live Kaktüs Doktoru hierarchy, the species node is attached to Mammillaria, the genus directly to Cactaceae, and the family to Caryophyllales. This package updates the species only. Cactoideae and Cacteae are stored as researched botanical classification fields without restructuring the live taxonomy-parent chain.

Native distribution and habitat

Kew summarizes the native range as north-eastern Mexico extending to Jalisco.1 The IUCN assessment reports a comparatively broad distribution and low overall decline and assigns LC — Least Concern.4 The old live origin statement that the species avoids high elevation and volcanic substrate is too categorical and unsupported and will be removed.

National and global conservation layers

Global LC does not mean the absence of every threat; habitat loss, illegal collecting, and local population pressure can still occur. The Mexican NOM-059 list and the IUCN assessment are separate systems.45 Documented nursery propagation should be preferred to reduce pressure on wild populations.

How synonymy is used

Synonyms support search, old-literature links, and nomenclatural history. Under Kew's broad circumscription, names including M. bocasana subsp. eschauzieri, M. haehneliana, M. hirsuta, M. icamolensis, M. knebeliana, M. kunzeana, and M. longicoma are historical synonyms here.1 The canonical taxonomy route follows the accepted name Mammillaria bocasana.

Mammillaria bocasana

Mammillaria bocasana is a clustering Mexican cactus whose white hair like radial spines and often hooked central spines create the familiar “powder puff” appearance. Stems may be globose when young and short cylindrical with age, and basal offsets can form multi headed clumps. The woolly surface is ornamental but also makes it important not to leave water trapped against the stem.
