A Flushing correspondent asks: "May I trouble you to tell me where the name of Diervilla was given to Weigela, and when?" [Diervilla was never given to Weigela. It is just the other way. The original name is Diervilla; Weigela is a newer name. It was thought to constitute a new genus, and was separated from Diervilla, but as our knowledge of the genus increased, it was found that there was not sufficient character to found a separate genus and so the name Weigela has to be dropped, and the individuals composing it go back to Tourneforts older name of Diervilla, in accordance with botanical laws of priority in nomenclature.- Ed.
