|discussion=<p><i>Euphorbia jejuna</i> is known in the flora area from only a few collections in Mitchell, Nolan, Terrell, and Val Verde counties. The species is very similar to <i>E. astyla</i>, but differs in its more deeply divided involucral gland appendages and more definitely petiolate, rounder leaves.</p>
