Summary Philippe van Tieghem's Recherches sur la structure du pistil et sur l'anatomie comparee de la fleur is shown to have been issued as a separate in I87I, although the volume of the journal in which it appeared was not completed until I875. The accurate citation for the journal is Mem. Pres. Divers Savants Acad. Sci. Inst. Imperial France. The frequently encountered citation Mem. Savants ?trangers is a ghost reference and thus should not be used. It is recommended that in bibliographies the reference be dated "I875" but that the following note be added after the citation: "Issued as a separate in 1871". In an addendum it is shown that G. Henslow's "second edition" (I893) of The origin of floral structures ... is merely a reprinting and not a second edition.
