Plum
A plum is a fruit of the subgenus Prunus of the genus Prunus. The subgenus is distinguished from other subgenera (peaches, cherries, bird cherries, etc.) in the shoots having terminal bud and solitary side buds (not clustered), the flowers in groups of one to five together on short stems, and the fruit having a groove running down one side and a smooth stone (or pit).
Mature plum fruit may have a dusty-white waxy coating that gives them a glaucous appearance. This is an epicuticular wax coating and is known as “wax bloom”. Dried plum fruits are called “dried plums” or prunes, although, in many countries, prunes are a distinct type of dried plum having a wrinkled appearance.
Prune
A prune is a dried plum of any cultivar, mostly Prunus domestica or European Plum. The use of the term for fresh fruit is obsolete except when applied to varieties grown for drying.Most prunes are freestone cultivars (the pit is easy to remove), whereas most other plums grown for fresh consumption are clingstone (the pit is more difficult to remove).
