As this species is so very similar to O. biennis and O. parviflora, most biologists are not aware of it. A tall species, it differs from O. biennis by the "Inflorescence being glabrous (or appearing so without magnification)", as opposed to "Inflorescence conspicuously pubescent" in O. biennis, according to Weakley (2018).
