1923] Fernald,—Southern Variety of Thelypteris fragrans 3 
saying "it is remarkable that the only specimens from those regions 
are what I here consider the var. £.”! Whether this southern variety 
actually oecurs in the Caucasus seems very doubtful. At least, 
Boissier clearly states that the record arose through an erroneous 
label? but the plant of temperate North America and temperate 
eastern Asia is clearly Hooker's Nephrodium fragrans, var. B, and 
since it is a well marked geographic variety it may appropriately 
be called:
