Usnea and its Linnaean Nomenclature.* — At the International 

 Botanical Congress, held at Brussels in 1910, it was decided to accept 

 Linnaeus's Species Plantarum as the starting-point for lichenologica-1 

 nomenclature. R. Heber Howe has taken the genus Usnea and ex- 

 amines the specific names in the light of Linnasus's determinations. He 

 finds that Linnams referred constantly to the figures and descriptions of 

 Dillenius. He gives the citations under each species, and finds that the 

 specially Linnaaan species are : Usnea plicata (L.) Web. ( U.ceratina Ach.) ; 

 U. barbata (L.) Web. (U.dasypoga) ; U. articulata (L.) Hoffm., and U. 

 florida (L.) Web., with the synonym Lichen hirtus L., the latter being 

 the sterile condition of the plant.
