The species of Mertensia belonging to the group of which M. panicu- 
lata (Art.) G. Don is the first described, are very difficult to identify and 
require a thorough study. The older botanists, e. g. LEHMANN and G. Don, 
have given names to several forms of which we know very little, but 
before creating new. species it will be necessary to try and clear up these 
older ones. At present we have no idea, if the new names M. alaskana 
Britton (Bull. New York Bot. Garden, vol. 2, No. 6, 1901, p. 181) and 
M. alaskana Eastwoop (Botan. Gazette, vol. 33, 1902, p. 287) are to be 
maintained or are to be taken as synonyms of old names. 
There is no doubt that the Mertensiæ of north-western North America 
consist of several nearly related species, and F. v. HERDER (Plante Rad- 
deanæ, in Rapper, Reisen in den Süden von Ostsibirien, Bd. IV, Heft 1, 18 
p. 229) is wrong in reducing Pulmonaria pilosa Cuam., P. lanceolata 
PursH, etc., to synonyms of Mertensia paniculata (Aır.) Don. 
The rich material collected by the Gjöa Expedition agrees well with 
the detailed description of Pulmonaria pilosa by A. DE Cuamisso (I. c.), 
with the exception that the corolla is not »circiter sesqui pollicaris«; but 
this is decidedly a lapsus calami by CHamisso, the corolla being only 
three quarters of an inch long. The same species — probably — has
