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. 



RANUNCULACKAE. 



Clematis virginiana L. Not rare. 

 Anemone cylindrica Gray. Very common.* 

 A. virginiana L. Not rfire. 

 Thalictruni purptirascens L. 



Ranunctiltis acris L. Vwry abundant in low grounds. 

 R . abortivus L 



Isopyrum biternatum, T. and G. 

 Aquilegia canadensis L. 



Delphinium azureum. Ait. Low grounds. Common. 

 D. exaltatum Ait. Very rare. One specimen in tiie 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.
