DIL has a listing under the headword "elefleog" for a plant identified
as atriplex or goose-foot. In modern nomenclature atriplex and
chenopodium are not the same, although they are related and look
rather alike, so this may indeed be an Irish name for the plant in
Variants given include "elefreog" and "elethreog", all of which have a
distinctly foreign look to them. Any ideas on the source word?
