|discussion=<p>B. L. Turner (1982) circumscribed <i>Seymeria bipinnatisecta</i> as a variable species ranging widely from the Arizona and Texas borders through much of northwestern Mexico. In the flora area, the species extends into the Sierra Madre of southeastern Arizona and the Edwards Plateau of central and southwestern Texas. Morphological variation in this range is continuous with that of the Mexican specimens. Gray admitted that he had not seen Mexican specimens of <i>S. bipinnatisecta</i> but created <i></i>var.<i> texana</i> based on perceived differences from the illustration of leaf and calyx incision, and of pedicel length by Seemann. Examination of specimens for this treatment indicates that the full range of diversity attributable to Mexican specimens for these characters can be found also in specimens of the Edwards Plateau. Most of the specimens collected in Texas are from the central Edwards Plateau; one clearly belonging to this species from Val Verde County on the Rio Grande (W. R. Carr 12406, TEX) is known; the range may not be discontinuous between Mexican and Edwards Plateau populations.</p>
