The Pumpkin Ash is a large tree as found 

 in the swampy bottom-lands of easter.i 

 Arkansas and southeastern Missouri, where it 

 attains the height of 100 ft. or more, with 

 columnar trunk 3 or 4 ft. in diameter above 

 its wide base. 



It inhabits deep swamps, the banks of 

 sloughs and streams of eastern Arkansas and 

 southeastern Missouri, and of the valley of the 

 Appalachicola River in western Florida. It 

 occupies these localities, inundated during a 

 considerable portion of the year, in company 

 with the Bald Cypress, Leitneria, Cotton and 

 Water Gums, Planer-tree, Swamp Poplar, 

 Water Locust, etc. The singular name, 

 Pumpkin Ash, by which it is popularly known, 

 is said to be given to it on account of its wide 

 swollen base which gives it stability in the 

 soft miry ooze in which it grows. The oc- 

 currence of the Pumpkin Ash, Leitnaria and 

 certain other Floridian species in southeastern 

 Missouri and eastern Arkansas indicates an 

 interesting extension of the Floridian flora 

 into those regions which is noteworthy, espe- 

 cially as few, if any, of these species have been 

 found in the intermediate regions.
