Its common names include American plantain, blackseed plantain, pale plantain, and Rugel's plantain.〔(''Plantago rugelii''. ) Germplasm Resources Information Network (GRIN).〕 The generic name ''Plantago'' is from the Latin ''planta'' ("footprint") and the species name ''rugelii'' honors Ferdinand Ignatius Xavier Rugel (1806-1879),〔(''Plantago rugelii'' Decne. ) Freckmann Herbarium. University of Wisconsin, Stevens Point.〕 a German-born botanist and pharmacist.〔(''Index Collectorum'', R. ) Department of Systematic Botany, University of Göttingen.〕 ==Description== This perennial herb grows from a taproot and fibrous root system. It produces a basal rosette of wide oval leaves with longitudinal veining and a somewhat waxy texture. The base of the petiole may be reddish or purple. A scape bears clusters of whitish flowers.
