Juglans boliviana

Juglans boliviana (), also known as Bolivian walnut is a tree in the family Juglandaceae and the walnut genus ("Juglans"). According to a paper in 1960 entitled "The Genus Juglans in South America and the West Indies" by American horticulturist and botanist Wayne Eyer Manning, it occurs in the Andes of northern Bolivia and central and southern Peru. 
Wayne Manning included the species "Juglans peruviana", described by French botanist Louis-Albert Dode in 1909 from nuts collected at an unknown locality in Peru, because the nuts closely match those of "J. boliviana" and apparently came from Metraro, where only "J. boliviana" is known.
