Rare Species of Rhexia L.

ABSTRACT
Three <em>Rhexia</em> species, <em>R. aristosa</em>, <em>R. parviflora</em> and <em>R. salicifolia</em>, are candidates for listing as endangered or threatened by the United States Fish and Wildlife Service. This current review of the rarity of <em>Rhexia</em> taxa was made through communication with botanists, literature review, and field and herbarium studies. <em>R. parviflora</em> is very rare while <em>R. salicifolia</em> and <em>R. aristosa</em> are restricted, yet more locally abundant.
