Pseudorontium is a genus of flowering plants with one species, Pseudorontium cyathiferum (syn. Antirrhinum cyathiferum), a New World snapdragon known by the common names dog's-mouth and Deep Canyon snapdragon. It is native to the deserts of northern Mexico and adjacent California and Arizona. It is an annual herb producing a hairy, erect, non-climbing stem with many oval-shaped leaves. The solitary flowers are dark-veined deep purple and white, often with some yellow in the throat, and are about a centimeter long. Previously considered to belong among the New World Antirrhinum species, it is now considered the sole member of the related genus Pseudorontium.
