Var. ANcusTIFOLIUM, Fenzl, l.c. i. 413, with cauline leaves narrowly 
oblong to linear, attenuate at the base, much fascicled and 9-15 lines 
in length, and var. LATIFOLIUM, Fenzl, 1. c. i. 412, with shorter oblong 
leaves, 6-8 lines long, broad at the base, are forms strikingly different 
in their extremes, but rather freely intergrading and often difficult to 
distinguish. The latter is perhaps a little more common in the Rocky 
Mountains but extends eastward to Labrador. Better marked are 
the following.
