Twenty-five species and two varieties of Psoralea, dis tributed among three segregate genera, were recognized from Texas by Rydberg (1919) and by Tharp and Barkley (1945, 1946). Fourteen species and four varieties, of which one species and three varieties are newly described, are recognized in the present synopsis, all treated under Psoralea. For the most part the dismemberment of the genus is entirely reasonable as far as Texas species are concerned
