Oriastrum

Oriastrum is a largely obsolete or historical term referring to a specific type of wild or uncultivated fruit tree, often a plum or other similar stone fruit. It generally describes a fruit tree that grows spontaneously, without deliberate planting or cultivation by humans. The term can also imply a fruit that is of inferior quality compared to its cultivated counterparts, often being smaller, less flavorful, or more prone to disease and pest infestation. It lacks modern botanical precision, and its usage is more common in older agricultural or horticultural texts.
