--><p>Zuckia was erected by P. C. Standley (1916) to include a solitary species, Z. arizonica, based on low, shrubby plants from saline, fine-textured substrates in northern Arizona. That taxon stood apart from Grayia brandegeei A. Gray, a species otherwise closely similar in the compression of the bracts and the horizontal position of the seeds. In the present treatment both taxa are included within an expanded Zuckia.</p>
