These 420 species must form the most conspicuous elements 
of our flora taken as a whole; and if there were roo: e, 
as follows: 
Composite, 57 minose, 14 
Cyperaceze, 53 Ranunculacer, 12 
Graminex, 39 late, il 
; 20 Salicaces, 11 
Serophulariacez, 15 Polygonaceze, 10 
{the former having a much larger number both of wid 
and of social plants than the latter); that the Hricacee and 07- 
chidacee fall to a low position, and that in their stead the Sali- 
cacee and the Polygonacee are among the largest orders. This 
is Owing to the general absence of Hricacee in our open oF pral- 
rie country west of the Alleghanies, and to the small number 
of Orchidacee which endure much diversity of climate.
