It belongs to the Aizoaceae family, and is listed as rare on the SANBI Red List, because it occurs in an area smaller than 68 km2, but it is not endangered there.

Cultivation

Grouped as a cactus or succulent by the genus Argyroderma, which is reliably one kind of plant (archetype table). The table holds no figure for this group, which spans too much for one minimum, and no habitat climate is derived yet; no cold floor is given, and no prose comes from the table.

Nothing derived: no habitat climate for this species, and the archetype table has no figure for its genus or family.

Climate across the habitat

No habitat climate can be derived: Only 1 distinct land cell of the climate grid holds an in-range record; three are needed for an envelope.

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing.
Openly licensed records inside the range, framed on where they fall.

Map marker-31.322, 18.663 · in the densest population, 4 records (100% of those in range)
Evidence usedThe map marker rests on all 4 georeferenced records inside the native range; the map shows only the 2 openly licensed ones, which alone would put the marker in the same place. Under a dozen records: treat the map as indicative. No climate envelope is derived for this species. 2 in-range records are placed to worse than 10 km and stay on the map but off the climate.
The map markerthe map marker: the openly licensed record nearest the middle of the densest 1° population of the 4 in-range records; it decides nothing.
