Alvordia is a genus of flowering plants in the family Asteraceae. It includes 4 species of shrubs which occur in the states of Baja California and Sonora, Mexico. The genus is characterized by having a secondary clustering of heads into compound units, so that what appears to be a single head is actually a group of heads packed together. The genus is classified as a member of subtribe Helianthinae, the same subtribe that contains the common sunflower (Helianthus). Based on the reported chromosome counts, Alvordia includes both diploid and polyploid species, but the relationships among these have not yet been studied in detail. No chromosome count has yet been reported for the species A. congesta from Sonora, which was a later transfer to the genus.
Heterosperma is a genus of flowering plants in the sunflower family, native to North and South America.

This genus is native to northwestern Mexico, particularly the Baja California Peninsula, but species are also found on the coast of Sonora, Guadalupe Island, and the Channel Islands of California.

Gambelia juncea is a species of flowering shrub in the plantain family commonly known as the Baja California bush snapdragon or Baja bush snapdragon. Gambelia juncea is a highly variable woody perennial to 1 m (3.3 ft) characterized by long, arching, reed-like stems and showy, bright red, two-lipped tubular flowers. Native to the Baja California peninsula and coastal Sonora, this species is widespread in the region across numerous habitats and has several varieties. It was formerly placed in the primarily South American genus Galvezia, but taxonomic studies have supported the reclassification of the two North American species into Gambelia. This species, with a number of cultivars, is widely used as an ornamental shrub for xeriscaping, erosion control, native plant gardens, and wildlife gardens.
