not marked as a favorite taxon Helianthus plantagineus (Torrey & A. Gray) E. Watson. Common name: Plantain-leaf Sunflower. Phenology: Jul-Sep. Habitat: Dry, open areas on sandstone outcrops and glades, Catahoula sandstone glades, Coastal Plain prairies. Distribution: Wc. Arkansas south to w. Louisiana (historical) and e. Texas. Specimens from Louisiana identified broadly as H. occidentalis (especially those identified to H. occidentalis var. dowellianus), may instead be this taxon, although closer examination of specimens is needed (see NO #18924, R.S.
