Lippia berlandieri Schauer[2] Lippia graveolens, a species of flowering plant in the verbena or vervain family, Verbenaceae, is native to the southwestern United States (Texas and southern New Mexico), Mexico, and Central America as far south as Nicaragua.

[1] Common names include: Mexican oregano, redbrush lippia, orégano cimarrón ('wild oregano'), scented lippia,[3] and scented matgrass.

[2] Fragrant white or yellowish flowers can be found on the plant throughout the year, especially after rains.

[3] The essential oil of Lippia graveolens contains 0-81% thymol, 0-48% carvacrol, 3-30% para-cymene, and 0-15% eucalyptol.

The first two components give the plant a flavor similar to oregano[2] (to which it is not closely related), and the leaves are widely used as an herb in Mexico and Central America.
