Discussion

Baileya pleniradiata is superficially similar to B. multiradiata and autumnal forms of the latter have often been misidentified as the former (see discussion under B. multiradiata). The two species occasionally occur together or in proximity; hybrids have not been noted. Style appendages readily allow distinction between the two taxa.
