PRELIMINARY LIST OF THE FLOWERING PLANTS 
OF ADAIR COUNTY. 
BY JAMES E. GOW. 
The collections on which this report is based were made 
chiefly during the summer of the year 1900, some of the 
work, however, having been done some years earlier. It 
is the hope of the author that he may in the course of time 
be able to supply a complete account of the flora of the 
county — one which will be exhaustive to the last detail. 
Heretofore such an undertaking has not been possible for 
him. The work has been done in the intervals of other 
work and has taken into account chiefly the more common 
species. It is here presented as preliminary to the more 
complete report which, it is hoped, will follow it. The 
grasses and sedges have been purposely reserved for a 
separate report. 
The nomenclature used is that of the sixth edition of 
Gray’s Botany. While more recent systems may have good 
claims to superiority, the nomenclature of Gray is more 
generally known than any other, and is better understood 
by the majority of amateur botanists. 
RANUNCULACEAE. 
Clematis virginiana L. Not rare. 
Anemone cylindrica Gray. Very common.* 
A. virginiana L. Not rare. 
Thalictrum purpurascens L. 
Ranunculus acris L. Very abundant in low grounds. 
R. abortivus L 
Isopyrum biternatum T. and G. 
Aquilegia canadensis L. 
Delphinimn azureum Ait. Low grounds. Common. 
D. exaltatum Ait. Very rare. One specimen in the author’s 
collection is certainly of this species. 
*In the case of the more common prairie species no attempt is here made to describe the 
habitat, or abundance of the species, except in cases where Adair county shows features which 
are novel and unusual. Most of the species are common and generally known As a rule, 
woodland species are noted in the text.
