Taxonomic Comments
Kartesz (1994 checklist) doesn't recognize varieties in this species but does recognize S. johnsonii. Sometimes placed in genus Echinocactus, Echinomastus, or Neolloydia (FNA 2003). FNA recognizes S. johnsonii and the varieties erectocentrus and acunensis (of S. erectocentrus) as distinct but transfers them to the genus Echinomastus. Morphological and molecular studies by Baker (2007, 2012) support the transfer of E. acunensis, E. arizonicus, and E. erectocentrus into E. johnsonii but transfer them back to Sclerocactus as S. johnsonii var. johnsonii (including E. arizonicus), S. johnsonii ssp. acunensis, and S. johnsonii ssp. erectocentrus (Baker and Porter 2016).

Number of Occurrences21 - 80
Rank Reasons
Known only from Arizona, New Mexico, and Sonora (Mexico), from perhaps several dozen sites altogether. Threats include drough, climate change, urban development, habitat degradation caused by law enforcement activities, habitat alteration by non-native invasive grasses, plant consumption and seed predation by insects (Moneilema gigas and Yosemitia graciella, respectively), and, potentially in the future, mining.
Range Extent Comments
Arizona, Pinal Co and Pima Co. to west Cochise Co., Maricopa Co., Organ Pipe Cactus National Monument. Mexico in adjacent Sonora.
Threat Impact Comments
Threats include drough, climate change, urban development, habitat degradation caused by law enforcement activities, habitat alteration by non-native invasive grasses, plant consumption and seed predation by insects (Moneilema gigas and Yosemitia graciella, respectively), and, potentially in the future, mining.
Ecology & Habitat

Habitat

Limestone of alluvial fans, flats, and hills in upper desert and in grassland.

Reproduction

Flowering begins in early March. This is the first cactus species to bloom in Organ Pipe Cactus National Monument, Arizona (Johnson 1992, see notes in pollination section).
