Discussion
Species 2 (1 in the flora).
Maurandella most commonly has been recognized as a genus segregated from Maurandya Ortega or as a section within Maurandya, based on distinctive characteristics: personate corolla, globular capsule, V-shaped septum, and marked asymmetry of the locules. The V-shaped septum results in unequal locule volumes, which is unique in Antirrhineae. Based on this unique combination of characteristics, Maurandella is recognized here as a genus distinct from Epixiphium and Maurandya.
Initial molecular phylogenetic studies indicated a sister group relationship between species of Maurandella and Maurandya (M. Ghebrehiwet et al. 2000); they lacked the taxon sampling needed to resolve relationships among closely related species in Epixiphium, Maurandella, and Maurandya (C. E. Freeman and R. Scogin 1999; P. Vargas et al. 2004). The more complete ITS sampling by M. Fernández-Mazuecos et al. (2013) placed both genera in the Cymbalaria clade, but not as sister taxa; Maurandya was sister to Lophospermum, whereas Maurandella was nested in a more basal position within a seven-taxon subclade comprising genera in subtribe Maurandyinae.
Maurandella hederifolia Rothmaler is known from northern Mexico.
