|discussion=<p><i>Gamochaeta coarctata</i> is native to South America and is also introduced in Mexico. R. K. Godfrey (1958) identified specimens of <i>G. coarctata</i> as <i>Gnaphalium</i> spicatum Lamarck. Some specimens from the flora area were misidentified by G. L. Nesom (1990f) as <i>Gamochaeta</i> americana (Miller) Weddell, which was described from Jamaica; it is widespread in Central America and Mexico, and has not been observed in the flora area.</p>
