Eight taxa in Verbena have been taxonomically difficult ( B. bipinnatifida, V. bipinnatifida var. latilobata, V. Wrightii, V. ciliata, V. ciliata var. longidentata, V. ciliata var. pubera, V. ambrosifolia , and V. ambrosifolia f. eglandulosa) . The taxonomic difficulties have been suggested to be the result of widespread hybridization. A flavonoid study of the populations belonging to these eight taxa, combined with a morphological survey resulted in the recognition of four taxa, Glandularia bipinnatifida var. bipinnatifida, G. bipinnatifida var. brevispicata, G. Wrightii , and G. chiricahensis . Hybridization is not responsible for widespread variation in this group.
