    Brushy hillsides and open places, often in disturbed soils, becoming a colonial weed of roadsides and cornfields, in the zones of tree-ipomoea, thorn-forest, and arid grasslands, on a variety of sedimentary and volcanic substrates, sometimes abundant on malpais, locally plentiful between 670 and 1700 (2040) m (± 2200-5700, rarely 6800 ft) in the Bajio country of the middle Lerma-Santiago valley and throughout the Balsas Depression, s.-centr. Mexico, from interior Nayarit to Michoacan, Guerrero, s.-e. Mexico, and Puebla, extending n., in scattered stations, along the e. slope of the Plateau from Veracruz to s. Tamaulipas, and s., becoming less common, through interior Oaxaca to Chiapas; apparently disjunct at 200-480 m (670-1600 ft) in the Zacapa desert of middle Rio Motagua in Guatemala; also, presumably as an old but locally naturalized introduction, in Cordillera Oriental in Colombia and n.-e. Venezuela. — Flowering (according to altitude) July to December. —Representative: MEXICO. Tamaulipas: von Rozynski 586 (NY). San Luis Potosi: E. & K, Roe 2346 (WIS).
