Photographs not checked
iNaturalist and GBIF media were skipped (not asked) when this page was built. Not asked, or not answered, is not "none": nothing here claims there is none. Why the site says it this way.GBIF's records not checked. GBIF's backbone holds no one accepted species of this name, and a name it holds only as another species' synonym is not taken for this one, so GBIF's records were not asked. So this page has no points on its map, no map marker, no habitat climate, no cultivation sheet and no species of nearest climate; the range is Kew's. Not a statement that none exist. How.

Cultivation
Grouped as a cactus or succulent, listed under the family Cactaceae in the archetype table, and Kew describes it as “succulent subshrub”.
How this section is made
Each card states this species' habitat figures with their sources, and what two fixed rules read from them; nothing here says what the plant does, wants or tolerates. The rules · the terms.
Group. Listed under the family Cactaceae in the archetype table, and Kew describes it as “succulent subshrub”. A group is taken only where Kew's description of the species agrees with the table's listing. The table gives no figure and no prose; the cold floor is the habitat's alone.
