Scientific classification
Kingdom: Plantae Division: Magnoliophyta Class: Magnoliopsida Subclass: Rosidae Order: Myrtales Family: Lythraceae Subfamily: Punicoideae (Horan.) Graham, Thorne & Reveal Genus: Punica
Species
Punica granatum L. Punica protopunica Balf.

Punica is a small genus of fruit-bearing deciduous shrub or small trees. Its better-known species is the Pomegranate (Punica granatum). The only other species in the genus, the Socotra Pomegranate (Punica protopunica), is endemic on the island of Socotra. It differs in having pink (not red) flowers and smaller, less sweet fruit.

Although previously placed in its own family of Punicaceae, recent phylogenetic studies have shown that Punica belongs in the family Lythraceae, and it is classified in that family by the Angiosperm Phylogeny Group.
