Dudleya, commonly known as liveforevers, is a genus of rosette-forming succulent plants in the stonecrop family, Crassulaceae, consisting of about ~70 taxa found in southwestern North America and Guadalupe Island. The genus is very morphologically diverse, with species ranging from large evergreen plants to tiny deciduous geophytic plants. The flowers of Dudleya have parts numbered in fives, with the petals arranged in tubular, star-shaped, or bell-shaped forms and, when fruiting, are filled with tiny, crescent-shaped seeds.

Sarcobatus is a North American genus of two species of flowering plants, formerly considered to be a single species. Common names for S. vermiculatus include greasewood, seepwood, and saltbush. Traditionally, Sarcobatus has been treated in the family Chenopodiaceae, but the APG III system of 2009 recognizes it as the sole genus in the family Sarcobataceae.

thumb|right|Grusonia parishiorum Grusonia is a genus of opuntioid cacti (family Cactaceae), originating from the North American Deserts in Southwest United States and northern Mexico, including Baja California. Authors differ on precise boundaries of the genus, which has been included in Cylindropuntia. Corynopuntia, also known as club chollas (or "perritos" in Mexico), is now a synonym, with the genus originally being described by Knuth in 1935. Molecular phylogenetic studies suggest that it should be included in Grusonia, a view accepted by Plants of the World Online .
