tentative as our knowledge of the phylogeny of these groups lies chiefly 
in the future, but it is just as well to express the little knowledge we 
have. The details of the list are carefully worked out as follows: 
name of family, with authors, synonyms and dates: number of genera 
and their general distribution; approximate number of species; name 
of genus, with author, place and date of publication; synonyms and 
dates; number and distribution of living species; number of extinct 
species if any have been recorded ; name of species, with full synon- 
ymy, dates, etc.; North American and local distribution; representa- 
tion in Minnesota collections. It will be seen that this gives a very 
large amount of information concerning the bibliography and range 
of each plant and will be of very great service to botanists. The list 
Is summarised as follows: families, 106; genera, 407; species and 
Varieties, 1174. :
