sub-species there is diversity, A being for climates of short season, 
C for long seasons, while B in general is intermediate, although a 
climate suitable for C can grow A and B. Sub-species A is the 
only kind represented in our more Northern collections of Z. zn- 
durata from Lake of the Woods, Northeastern Canada and North 
Dakota; of Z, amylacea from Manitoba; of Z. inmdentata from — 
North Dakota; of Z. saccharata from Northern Maine and North- 
€rn Minnesota. Sub-species B comes from a little south of the 
before-mentioned range, and extending south especially through- 
out the elevated regions. Sub-species C is yet more southern, 
and rarely comes to me from regions of short season.
