Palafoxia arida
Plants of Palafoxia arida 90–150 cm with phyllaries 16–25 mm (from dunes west of Yuma, Arizona) have been treated as var. gigantea. Plants referable to P. arida have been named P. linearis (Cavanilles) Lagasca (including var. gigantea M. E. Jones) in other floras; P. linearis is a Mexican species (see B. L. Turner and M. I. Morris 1976).
