about three miles south of Port Allen, La. This levee had a 

 longer and Hatter base which is very sandy and in places mixed 

 with silt loam. On this bench the vegetation was not as thick 

 as on the new levee. However the slope of the levee proper 

 had a thick sod and contained a smaller variety of plants as 

 compared to the slope of the new levee. As this spot had never 

 been visited before, it is impossible to compare the effects of 

 the flood on the old levee. A study of the lists of plants from 

 both sites does not show many differences. 



In October 1927 the writer visited Melville, La. and other 

 points in the flooded region. All along the road one could see 

 the high water mark, on fences, trees, and buildings. The 

 water mark was a foot or so above the ground in some places, 

 a foot or more above the tops of the windows of the houses 

 in others. 



In this region the most striking feature was the abundance 

 of two weeds, Xanthium chinense Mill, and Croton sp. These 

 were so abundant as to appear as if they were planted crops. 

 An examination of this region in March 1928 shows that there 

 is a high percentage of germination of the cocklebur as well as 

 other weeds. 



Specimens of most of the plants listed have been preserved 

 in the Louisiana State University Herbarium. Many duplicates 

 have been sent to the New York Botanical Garden and to the 

 University of Michigan Herbarium. 



The nomenclature mainly follows that of Small's "Flora of 

 Southeastern United States."
