140 MISSOURI BOTANICAL GARDEN. 



ical Garden only, I did not collect sets for distribution, but 

 have since put up what duplicates I had left, in a few sets, 

 at the suggestion of Dr. Trelease. 



The result of the work is, that we now know that we 

 have a Floridan and Georgian flora, which extends up the 

 Mississippi Valley in a northwesterly direction to South- 

 eastern Missouri, where it meets a Texan Flora, which 

 extends south westwards to Texas.
