The name "ground elder" comes from the superficial similarity of its leaves and flowers to those of elder ("Sambucus"), which is unrelated.  It is the type species of the genus "Aegopodium".

Kaneshiro Kofuku: Kaneshiro Kofuku (born Kofuku Kaneshiro; February 27, 1953 - December 29, 2002) was a sumo wrestler from Takanabe, Miyazaki, Japan.  He made his professional debut in September 1969, and reached the top division in September 1974.  His highest rank was sekiwake.  After being runner-up in the January 1979 tournament and winning the Fighting Spirit prize he changed his shikona or fighting name to Tochihikari, in honour of ozeki Tochihikari Masayuki, who also fought for Kasugano stable.  However, after falling back to the juryo division in 1985, he was no longer considered worthy of such a prestigious name and so reverted to Kaneshiro, his birth name.  He left the sumo world upon retirement in May 1987, unable to acquire elder stock in the Japan Sumo Association and remain as a coach.  This was because the Sumo Association had introduced a rule in 1976 requiring Japanese citizenship to become an elder, and Kaneshiro, because of his Korean parentage, was not eligible until it was too late.

Privet: A privet is a flowering plant in the genus Ligustrum.  The genus contains about 50 species of erect, deciduous or evergreen shrubs, sometimes forming small or medium-sized trees, native to Europe, north Africa, Asia, many introduced and naturalised in Australasia, where only one species extends as a native into Queensland.  Some species have become widely naturalized or invasive where introduced.  "Privet" was originally the name for the European semi-evergreen shrub "Ligustrum vulgare", and later also for the more reliably evergreen "Ligustrum ovalifolium" used extensively for privacy hedging, though now the name is applied to all members of the genus.  The generic name was applied by Pliny the Elder (23–79 CE) to "L. vulgare".  It is often suggested that the name "privet" is related to "private", but the OED states that there is no evidence to support this.
