45, see text Sanchezia is a genus of the plant family Acanthaceae.

[1] Members of this genus are shrubs, rarely small trees or herbs, occurring in the lowlands of tropical South and Central America.

[2] Because they have large, colorful bracts and flowers, and sometimes even colorful leaves, several species are cultivated as ornamental plants throughout the tropics and in botanical gardens of temperate areas.

In some areas, ornamental species have become problematic as invasive weeds.

Sanchezia is named for José Sánchez, a nineteenth-century professor of botany at Cádiz, Spain.
