Origin: Native

Herbarium search: CPNWH

Notes: FNA9: "Three races of Aphanes occidentalis are recognizable, apparently corresponding to previously described species. Because some apparently intermediate plants exist and, as not all specimens can be confidently assigned to these races, they are not being recognized formally here. It is also possible that they represent independent introductions rather than native species, although no European or North African species are known with the characters they exhibit. "
