Description
Keckiella antirrhinoides is desert shrub that 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 inflorescences which bear snapdragon-like flowers. Each hairy, glandular 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.
