Duplicate Binomials—My attention has recently been drawn 
to the use of specific names identical with the generic by H. 
Karsten, in his “ Deutsche Flora,” a pharmaceutical work of great 
value published in Berlin (?) from 1880 to 1883. As this ante- 
dates their acceptance in America, I here abstract those which 
apply to indigenous or introduced American plants. Our copy 
does not indicate the exact dates of the pages. Presumably the 
book was published in parts, and reference to an unbound copy 
will most likely be necessary for closer approximation than that 
given above.
