Discussion
Species 2 (2 in the flora).
Mohavea is similar to Pseudorontium, which also has asymmetric, winged seeds. Seeds of Mohavea are notched at the proximal end. Plants of the genus can be distinguished from others in Antirrhineae by their relatively large, acute or obtuse corolla lobes, more or less radially symmetric fruits, and two fertile anthers, each with a single pollen sac. R. K. Oyama and D. A. Baum (2004) and M. Fernández-Mazuecos et al. (2013) found evidence that Mohavea nests among species treated in Sairocarpus.
Selected References
