The examination of a large suite of herbarium specimens, 
partieularly in the light of recently acquired material, has led 
the writer to place a somewhat different interpretation on this 
species than formerly; hence, a brief description is here given 
and a few specimens from widely distributed exsiccati, well 
illustrating the species, are cited.
