R. C. Rollins (1947, 1993), the limits of Sibara are highly artificial. One of the ten species that he recognized, S. virginica, is here placed in the monotypic genus Planodes of the tribe Cardamineae. Another, S. viereckii, is assigned to Dryopetalon, and S. grisea is reduced to synonymy under Thelypodium texanum. The four Mexican species recognized in the genus are S. angelorum (S. Watson) Greene (Baja California, Sonora), S. brandegeeana (Rose) Greene (Baja California), S. laxa (S. Watson) Greene (Baja California), and S. mexicana (S. Watson) Rollins (Guanajuato).</p> |tables= |references={{Treatment/Reference |id=rollins1947a |text=Rollins, R. C. 1947. Generic revisions in the Cruciferae: Sibara. Contr.
