Pompia(Citrus medicavar.tuberosa), also calledpumpia,sa pompia,spompia,andChina citron,is aCitrushybridcultivated for its ediblefruit.[1]It is a taxonomical synonym ofCitrus medica.[2]
Distribution
[edit]Pompia originated and is found only inSardinia,especially the eastern half, where it can be found growing wild incitrusgroves and cultivated in backyards and orchards.[3]The earliest descriptions of it date back to 1780 and it likely originated around 1760 inMilis.[4]
Description

Thefruitis moderately large (at least as large as agrapefruit), round and sometimesoblateor square in shape, and has a rough, warty, yellow (green when unripe), thick, and sometimes ribbedrind.It sometimes has a circular depression in the top or bottom. The inner pulp is acidic, yellow, and mostly dry and is generally considered inedible;[5]it has been described as bitter and chewy. It has a subtle fragrance and contains 13–14 wedges with largevesicles.It is usually seedless but may contain one to threepolyembryonicseeds which measure 8 to 12 millimeters (0.31 to 0.47 inches) in length and are roughly triangular in shape. It weighs up to 1.5 pounds (0.7 kilograms). The tree is densely branched and grows 2 to 3 meters (6.6 to 9.8 feet) in height and has an expanded and erect posture. Thepetioleis unwinged and measures 6–10 millimeters in length. The leaves areellipticalin shape and are dark green in color; they are leathery and theapexis rounded in anovatetolanceolateshape. Themarginisentireand themidribis very defined. Theflowersare white in color and are either solitary or in clusters of two to eight; they usually have fivepetals.They have numerousstamensanddorsifixedanthers,and thestigmais round and green in color and irregularly lobed. The tree fruits from October to February or March.[4]

The fruit has been grown and cultivated for at least two centuries inSardinia;however, it did not gain international popularity until the 1990s, when a large orchard of pompia trees were planted as part of a social farming project. Since then, it has become a presidium ofSlow Food.[6]It is most notably used insa pompia intrea,a traditional dessert ofSiniscolain which the rind of the fruit is candied and then covered with honey and served on an orange leaf. It is also used in variousliquors[7]and is sometimes grafted ontosour orange.[4]
Genetics
[edit]Before the parentage was confirmed, the pompia was thought to be a hybrid of acitronandgrapefruitor citron andlemon;however, recent studies have proven the pompia to be a hybrid of the citron (Citrus medica) and thesour orange(Citrus aurantium), with the citron being the pollen parent and the sour orange being the seed parent. The variety of the citron parent has not been confirmed, but it is likely aDiamante citronor a common poncire. The pompia is genetically synonymous with theRhobs el Arsaand Poncire de Collioure citrons. Theessential oilcomposition in the leaf is closer to that of a citron, while the essential oil composition in the zest is closer to that of a sour orange.[1]The major compound in the fruit islimoneneat 94%, and it contains smaller amounts ofsesquiterpenesand its derivatives.[8]The rind of the fruit containsantioxidantsubstances[9]and the leaves containantimicrobialsubstances that killListeriabacteria on foods.[10]
