We have no doubt but that this is the Lythrum datum 

 of Pursh, though he describes the flowers as being very 

 small and the leaves acute ; the first circumstance may be 

 accounted for from the author's having seen the dried plant 

 only, in which state the flowers shrink almost to nothing, 

 and as to the second, although we have generally found the 

 leaves obtuse, sometimes even a round-oval, yet we have 

 seen one specimen in which they were narrow and acute. 



Native of Georgia and South-Carolina. Flowers in June, 

 July, and August. A herbaceous perennial, requiring pro- 

 tection from severe frost. Propagated by parting its roots, 

 or by seeds. Introduced by Mr. Lyons, in 1812. Com- 

 municated by Mr. Knight, of the Exotic Nursery.
