Pyxidanthera is a genus of flowering plant in the family Diapensiaceae.
[1][2] Furthermore, these two designated species were found to not be reciprocally monophyletic.
[3][4][5] Despite these findings, some flora still recognize these two species based on their range, habitat, and leaf morphology (size and pubescence).
[4][6] However, these leaf morphology differences are directly related to habitat and moisture.
The most widespread species, Pyxidanthera barbulata, is native to the eastern United States, occurring on the coast from Long Island to New Jersey and Virginia to South Carolina.
