|etymology=Arabic sofera, name of yellow-flowered plant, possibly Cassia sophera; Greek sophorum, wise men, alluding to occurrence of distinct stamens in papilionaceous flower as unnatural and to circumscription of papilionaceous group

|discussion=<p>Species ca. 50 (4 in the flora).</p><!--
--><p>Sophora as traditionally circumscribed is recognized as an unnatural assemblage. Molecular studies have elucidated the relationships among taxa in Sophora in the broad sense, resulting in recognition of several smaller genera. In the flora area, Sophora, as currently circumscribed, comprises herbaceous plants arising from a woody root, and the woody species S. tomentosa. Two species in the flora area that formerly were included in Sophora are now included in Dermatophyllum (D. arizonicum and D. secundiflorum), as is the closely related Mexican species D. gypsophilum and two others are placed in Styphnolobium (S. affine and S. japonicum). Styphnolobium is distinct from Sophora (in the narrow sense) in molecular studies, falling into the Cladrastis clade; Dermatophyllum is in a separate lineage from the Cladrastis clade and outside a clade in which the North American taxa of Sophora (in the narrow sense) fall (J. J. Doyle et al. 1996; R. T. Pennington et al. 2001; M. F. Wojciechowski et al. 2004).</p><!--
--><p>The seeds and foliage of some species of Sophora contain neurotoxic alkaloids. Although neurotoxicity has not been demonstrated in native Sophora species, G. E. Burrows and R. L. Tyrl (2013) discussed possible teratogenic effects.</p>
