Discussion

Polygala appendiculata is part of a widespread complex in Latin America, potentially representing more than one evolutionary lineage. Even if found to be a single lineage, it is one with a complicated nomenclatural history (J. F. B. Pastore 2013).

Polygala glochidata occurs in Cochise, Pima, and Santa Cruz counties.
