Amelanchier lamarckii, commonly known as the Snowy Mespilus or Juneberry, is native to eastern Canada and north east USA. This species is believed to be a hybrid and should technically be know as Amelanchier x lamarckii. This tree has naturalised over much of western Europe.

The etymological root of the binomial name Amelanchier is from French Provencal name ‘Amelancier’, an old name for Amelanchier ovalis. Lamarckii is named after Jean Baptiste de Monet Lamarck, a 19th century French naturalist and author.
