That is exactly the misinformation I was talking about. Waxberries are emphatically not Myrica rubra.
QuoteWaxberries are Gaultheria appressa, from Australia Myrica pensylvanica, from eastern North America Pollichia campestris, from eastern Africa and Arabia Symphoricarpos, a genus of the honeysuckle family. The name "waxberry" is also a common mistranslation to the Chinese fruit, Yangmei (杨梅) Zhang gao or Myrica rubra.
