The first use of "Prunus" as a genus name was by Carl Linnaeus in "Hortus Cliffortianus" of 1737, which went on to become "Species Plantarum". In that work, Linnaeus attributes the word to "Varr.", who it
Prunus brigantina to other "Prunus" species are not yet clear, as an initial molecular phylogeny found that various DNA sequences gave ambiguous indications, and it did not appear to belong in a clade with "Prunus armeniaca". Prunus brigantina Prunus brigantina, called Briançon apricot, marmot plum, and alpine apricot, is a wild tree species native to France and Italy. It is the only apricot-like "Prunus" species native to Europe. The fruit is similar to the commercial apricot "Prunus armeniaca", and is edible. An edible oil produced from the seed, 'huile des marmottes', is used in France. Unlike the other closely related species known
