|discussion=<p><i>Packera tampicana</i> is fairly widespread along the Gulf Coastal Plain and north and in Mexico. Morphologically, <i>P. tampicana</i> most closely resembles <i>P. glabella</i>; the former grows in very wet, sandy or clay soils and open sunlight, the latter grows in drier habitats, usually in partial shade.</p>
