—Dr Pease is correct in stating that the umbellifer on the cover of the Nov 27 issue of JAMA is not D carota (Queen Anne's lace). It is difficult to determine precisely the species illustrated without seeing a specimen or knowing where the photograph was taken, but it appears to be a species of Angelica, perhaps A venenosa of the eastern United States or a related species.
