publication of Torrey and Gray’s Flora of North America no 
systematic arrangement of our Ranunculi has been attempted. 
A number of our species ars now referred to older names than 
those generally cited, and some additional ones are charac- 
terized. KR. aguatilis, var. divaricatus, Gray, of the Manual (var. 
stagnatilis, DC.) is regarded as a good species under the name 
R. circinatus, Sibth; R. hederaceus, L., occurs in fresh-water 
marshes at Norfolk, Va., probably introduced from Europe; X&. 
triternatus, Gray, is a new species from Klikitat County, Oregon, 
distributed by Howell, as R. Hookeri; R. Arizonicus, Lemmon, 
from the Southwest, is recognized, and two varieties of it are 
noted; &. Suksdorfii, from Mt. Adams, Washington, is here 
first described; R. occidentalis, Nutt., includes R. Nelson, Gray, 
and five varieties are made of it; A. acriformis, Gray, from the 
Rocky Mountains, is the R. acris of Hooker. R. hispidus, 
Michx., a northern and western species, is distinguished from 2. 
Pennsylvanicus, L.£; R. septentrionalis, Poir., includes most of 
our forms which have gone as R&. repens, L., the latter species 
being mainly confined to low grounds near the coast, where it 
has been introduced, but is also indigenous in some localities ; 
R. fascicularis, Muhl., is regarded as distinct.
