1 hesitate to form the new combinations necessary to distinguish them as such, 
especially as the tendency in nomenclature is to do away with varietal distinctions 
as much as possible. Nylander attributed his subfastigiata to our area (a con- 
tingent well-marked phase of the present species) but evidently had not seen 
subampliata from America, Mr. Merrill being the first one to attribute it to our 
lichen flora.

NOTES ON NOMENCLATURE— XII 
Elizabeth G. Britton 
Since the completion of the mosses in the Engler and Prantl Pflanzenf ami- 
lien when my last note was printed 1 a number of corrections and additions have 
come to our notice. Last year in the Revue Bryologique 2 Monsieur Cardot has 
been giving a series of notes which it would seem worth while to condense and 
repeat in the Bryologist and we have also a few changes of our own to make 
which have reposed in our herbarium for some time, and which it behooves us 
to put on record.
