Discussion
The name Washingtonia filifera var. robusta (H. Wendland) Parish is nomenclaturally a synonym of W. robusta, although it was applied by S. B. Parish to palms now known as W. filifera. Hence, Parish's variety has been included erroneously by L. H. Bailey (1936) and others in synonymy under W. filifera.
Washingtonia robusta is widely cultivated in warm areas in the United States and has occasionally naturalized in Florida (S. Zona 1997) and southern California (J. W. Cornett 1986).
