Discussion
Species 1.
Pseudorontium is similar to Mohavea in having winged seeds, but R. K. Oyama and D. A. Baum (2004) and P. Vargas et al. (2004) found Pseudorontium positioned well outside the taxa usually included in Antirrhinum in both the narrow (D. A. Sutton 1988) and broad (D. M. Thompson 1988) senses. ITS results in M. Fernández-Mazuecos et al. (2013) placed Pseudorontium and Mohavea in different clades; Pseudorontium was sister to Galvezia. The pendent, globular capsules, eccentrically winged seeds, and lack of twining branches distinguish P. cyathiferum from species of Sairocarpus.
