PART II. 



FLORA. 



The aim of the following flora is to include every na- 

 tive, naturalized or adventive higher plant, wrhich is known 

 certainly to grow in Boone county. Practically the flora 

 is complete only for the immediate vicinity of Columbia. 

 Over nine-tenths of the whole number of plants listed oc- 

 cur within a radius of five miles of Columbia. The flora 

 of the cliffs, bottoms and shores of the Missouri river is 

 but imperfectly known, and no work whatever has been 

 done in the more remote northern, eastern and south- 

 eastern portions of the county. 



Nevertheless the list contains 1058 species belonging to 

 435 genera and 101 families. There can be no doubt but that 

 when the whole county shall have been adequately explored, 

 the number of species will considerably exceed that found in 

 Jackson county, from which 1141 species are known. There 

 are appended also 85 species reported by Tracy in the Flora 

 of Missouri, but which have not been verified for this list, 

 though many of them doubtless are to be found in Boone 

 county. 



No plant that has not passed through the author's hands 

 has, with perhaps two exceptions, been admitted to the list. Of 

 most of them specimens are to be found in the Boone County
