specific name should retain its earlier form, rigidior, and not be changed 
as by several recent writers to the positive degree. The restoration of 
the varietal name ambiqua is necessitated by Art. 48 of the Vienna Rules 
and rests upon the fact that ambigua, not longifolia, was the name 
first applied to this plant in the varietal category.

THE DISCOVERY or CRYPTOGRAMMA STELLERI IN MAINE.— 
Cryptogramma Stelleri (Gmel.) Prantl (Pellaea gracilis Hook.) has 
not been reported, I believe, from Maine. On July 29, 1906, I found 
it growing in abundance at Berry Ledge in West Paris. The plants 
were not on limestone, but upon a coarse granitic formation. When 
acid was applied to the rock, however, it caused effervescence, show- 
ing the presence of lime in the rock.— WALTER L. Bacon, Norway,

Two ADDITIONS TO THE LICHEN FLORA or THE BLUE Hirrs.— 
I have found lately in my herbarium the following species of lichens
