Genus and molecular evidence
The genus Kimnachia preserves a distinct lineage of epiphytic cacti that did not belong to Pseudorhipsalis in the chloroplast analysis. Establishing the genus aligned its circumscription with the evolutionary history reconstructed from DNA. The closest placement of this lineage within the larger group remained unresolved.
