|discussion=<p>Variety triligulata was described from the cliffs of Boquillas Canyon, on both sides of the Rio Grande in Texas and adjacent Coahuila, Mexico. The variety has elongate involucral gland appendages that are divided into three to five linear, straplike segments; it appears to represent a distinctive, localized population within the overall distribution of <i>Euphorbia chaetocalyx</i>. More generally, populations of <i>E. chaetocalyx</i> from elsewhere in northern Coahuila, Mexico, have similarly shaped involucral gland appendages and may represent additional populations of <i></i></i>var.<i><i> triligulata</i>.</p>
