|discussion=<p><i>Schwalbea americana</i> is among the more fire-dependent species in the flora, responding favorably to annual burns. Documented host plants include <i>Aletris farinosa</i>, <i>Carphephorus odoratissimus</i>, <i>Gaylussacia dumosa</i>, Ilex glabra, and <i>Pityopsis graminifolia</i>. It has declined greatly since the advent of widespread fire suppression and is now federally listed as endangered; extant populations occur in Florida, Georgia, Louisiana, New Jersey, North Carolina, and South Carolina. Chaffseed was reported from eastern Texas by D. S. Correll and M. C. Johnston (1970); no voucher has been seen.</p><!--
--><p><i>Schwalbea americana</i> is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
