Keckiella antirrhinoides (formerly Penstemon antirrhinoides) is a species of flowering shrub in the plantain family known by the common names snapdragon penstemon and chaparral beardtongue. It is native to the chaparral, deserts, and pinyon-juniper woodlands of California, Arizona, and adjacent Baja California. This shrub grows one half to two and a half meters tall, with spreading branches. The oppositely-arranged leaves are up to 2 centimeters long and are lance-shaped or narrow ovals. They are deciduous during dry periods. The plant produces branchlike flower clusters which bear snapdragon-like flowers. Each hairy flower is about 2 centimeters wide, with three lower lobes which lie flat or curve down and two upper lobes which join to form a curved lip. Inside the flower are shiny filamentous stamens holding anthers and a flat, densely hairy sterile stamen called a staminode. The flowers are light yellow and dry to nearly black. The plant will often drop many leaves after flowering.
