89. Fraxinus Americana profunda. 



Abundant in the swamps of Dunklin and New 

 Madrid counties. Sept. So far as can be seen from 

 his figure, the same as Wenzig's F. platycarpa Flori- 

 dana, but it is possible that his figure is actually from 

 young specimens of platycarpa. Differs from the 

 usual form of Americana in the strong pubescence of 

 the shoots, the large size of the leaves, and the very 

 large fruit, the shaft of which is often strongly 

 six-sided. 



90. Fraxinus viridis pubescens Hitchc. 



Common in the swamps of Dunklin county. Sept, 

 I would suggest that the subspecific name ought to 

 have been subpubescens, as there is some likelihood of 

 confusing this with F. pubescens which I take to be a 

 good species. 



91. Asclepias perennis Walt. 



Common in the swamps of Butler, New Madrid and 

 Dunklin counties. Sept.
