Without getting into the details here, all of the observations of Andropogon glomeratus in Texas (among some other areas) should be swapped into Andropogon tenuispatheus. There are over 3,700 observations in Texas, so manually changing all of the observations and hoping to get enough identifiers to agree seems overly cumbersome and impractical. We can’t just swap all of A. glomeratus into A. tenuispatheus, because A. glomeratus is still a valid taxon in other areas. Is there a way to swap only the A. glomeratus observations in Texas to A. tenuispatheus?
For those interested in the swap, search the observations for those two taxa for the most discussions, and review the following paper:
