THE ALLEGHANY SLOE (Prunus Alleghaniensis, Port) A shrub or small tree with gnarled, thorny branches, that spreads in thickets on mountain slopes, near watercourses, on both sides of the Allegheny Mountains, in Pennsylvania. Fruit black, small, juicy, sour, fine-flavored when made into jams, jellies, and preserves. The Black Sloe (Prunus umbellate Ell.), found on sandy bottom land, near the coast from South
Carolina all the way to the Mississippi delta, and up the river to Arkansas, supplies the tart wild fruit to local markets, where people far south are quite as fond of preserves made of their black sloe as are the Pennsylvanians. The drupes are pea size in both species.
