|discussion=<p>Schwalbea americana is among the more fire-dependent species in the flora, responding favorably to annual burns. Documented host plants include Aletris farinosa, Carphephorus odoratissimus, Gaylussacia dumosa, Ilex glabra, and Pityopsis graminifolia. 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>Schwalbea americana is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
