Prunus brigantina explained

Prunus brigantina, called Briançon apricot (French: Abricotier de Briançon), Briançon plum (French: Prunier de Briançon), marmot plum (French: Marmottier), and Alpine apricot, is a wild tree species native to France and Italy.^{[1] [2]} Its fruit is edible and similar to the commercial apricot P. armeniaca,^[3] but it is smooth unlike apricots.^[4] An edible oil produced from the seed, 'huile des marmottes', is used in France.

It is disputed whether P. brigantina is an apricot or a plum. It is grouped with plum species according to chloroplast DNA sequences,^[5] but more closely related to apricot species according to nuclear DNA sequences.^[6]
