2 numbers being the short-scaled tree, 7 the long-scaled. Fruiting 
specimens from Newfoundland and Labrador are wanting, but it is 
significant that nearly all material at hand from Connecticut (6 out 
of 7 collections), New York (9 out of 10) and Tennessee (2) are of 
the long-scaled extreme. Whatever factor may influence the dis- 
tribution of the two it would seem that the typical short-scaled B. 
lutea cannot be regarded as generally of more southern range than 
the other. 
To summarize, the two varieties of Betula lutea are:
