REPORT ON THE BOTANY OF JACKSON COUNTY. 



BY B. FRANK BUSH. 



In December, 1882, the writer published a list of the plants he had 

 found growing in Jackson County, which included 609 species and mark- 

 ed varieties. 



During the season of 1883 and '84, with the assistance of Mr. 

 Cameron Mann, of Kansas City, he was enabled to increase the number 

 of species native to that county to 906, and the result of their united 

 labor was published in February, 1885. 



It was the opinion of the authors of the supplement to the Flora of 

 Jackson County that the number of species inhabiting our district would 

 not fall short of 1,000, and the appended list shows how well that opin- 

 ion was founded. 



Particular attention has been given to the Sedges, Grasses and Com- 

 posites, and the reader will not wonder if their number is out of pro- 

 portion. 



The largest family in our district is the compositae being represen- 

 ted by 140 species. Graminacae follows next with 117 species, and then 

 come the Sedges with 91 species. 



The largest genera of our Flora are Carex, Panicum and Cypems, 

 having respectively 54. 22 and 19 species. 



It is thought best that the numbering should be continuous, and 

 when the work is re-written references may be given to plants by num- 

 bers. 



The writer is under many obligations to Prof. Sereno Watson, Prof. 

 N. L. Britton and Dr. Geo, Vasey, for assistance rendered in kindly de- 

 termining obscure species, and by notes and suggestions given. 



The following list brings the Flora of Jackson county up to date, 

 and should the reader notice any omission he will confer a favor by in- 

 forming the writer of it:
