|discussion=<p>Species 6 (3 in the flora).</p><!--
--><p>Two other generic names have been used for taxa now placed in Dermatophyllum, in addition to their placement in Sophora: Agastianis Rafinesque and Calia Terán & Berlandier (G. P. Yakovlev 1968). Agastianis is superfluous and an illegitimate substitute for the nomenclaturally rejected name Broussonetia Ortega (1798). Calia is considered a later homonym of Calea Linnaeus (1763, Asteraceae; K. N. Gandhi et al. 2011).</p><!--
--><p>Dermatophyllum is a segregate from Sophora. It is considered distinct from Sophora by its woody habit; thick, leathery leaflets; blue, violet, or white petals; calyx with obvious teeth or lobes; flattened to terete legumes; and geographic range. The distinction is supported by molecular data indicating that Dermatophyllum (as Calia) falls into a separate clade from Styphnolobium and other Sophora species (K. N. Gandhi et al. 2011; G. P. Lewis et al. 2005; R. T. Pennington et al. 2001; M. F. Wojciechowski et al. 2004).</p>
