Discussion
Pseudognaphalium micradenium has a more northern and Appalachian distribution than P. helleri. A report of P. micradenium for Louisiana probably was based on specimens of P. helleri. The two species differ in vestiture and other features; stems of P. micradenium are more slender than those of its close relatives.
