A Lepidoptera-flower known to be fertilized by moths and 
butterflies in North Norway, Scotland, England, and the Alps. 
Some differences in the length of the spur are to be noted ; it 
is recorded as 10-11 mm. long in North Norway, 15 mm. in 
South Sweden, 13-14 mm. in the Alps, and is 10-12 mm. 
long at Clova. We have watched flowers at night without 
observing insects to visit them.
