Leucophyllum frutescens is an evergreen shrub in the figwort family, Scrophulariaceae, native to the U.S. state of Texas, where it is the official "State Native Shrub of Texas", and to the states of Coahuila, Nuevo León, and Tamaulipas in northern Mexico. Although commonly known as Texas sage, it is not a true sage and is distinct from the genus Salvia. The species is also called Texas Ranger, Texas rain sage, cenizo, Texas silverleaf, Texas barometerbush, ash-bush, wild lilac, purple sage, senisa, cenicilla, palo cenizo, or hierba del cenizo.

Ephedra antisyphilitica is a plant species native to the southern Great Plains of the United States (Oklahoma, New Mexico, Texas), and also to northeastern Mexico (Nuevo León, Coahuila, San Luis Potosí). This species should not be confused with the 1871 name Ephedra antisyphilitica S.Wats., native to further west in the Southwestern US and in Baja California. Meyer's use of the name dates from 1846, so it has priority over Watson's later application of the same name to a different plant. Watson's plant is now called Ephedra nevadensis.

Ehretia anacua is medium-sized tree found in eastern Mexico and southern Texas in the United States. It is a member of the family Ehretiaceae. One of its common names, anacua, is derived from the Mexican Spanish word anacahuite, as is that of the related Cordia boissieri, the anacahuita. That word in turn is derived from the Nahuatl words āmatl, meaning "paper," and cuahuitl, meaning "tree," possibly referring to the bark. It is also known as knockaway, a corruption of anacua, and sandpaper tree. Alternate spellings are anaqua and anachua.
