In terms of herbarium collections this taxon appears to be known only
from the type, as cited above. It is represented in a few living collections,
but survives and flowers only with difficulty and can be easily con¬fused
with forms of Schiumbergera russel¬liana when sterile. Its conservation
status is cause for concern even though at least part of its habitat
is included within a national park.
