This usually very common and somewhat variable species was 

 not detected in the upper portions of our territory, althou<>'h 

 many localities seemed favorable for its growth. There has been 

 no attempt to segregate the numbers given above into forms. 

 Three forms have been separated, however, by others and are 

 quoted below.
