| Cultivar | Lumia |
The lumia (Citrus × limon var. 'Lumia', Citrus lumia Risso. & Poit., or Citrus aurantiifolia (Christm. et Panz.) Swingle var. lumia hort.[1]) is also called the pear lemon (Citrus x lumia 'pyriformis'), remarking it's shape that resembles a pear. It is also called French lime and sometimes sweet lemon, even-though it is not necessarily sweet.
In German, the lumia is called Birnenlimone, Patriarch-Citrone, Süsse Limone[2] or Birnenlumie, in French it is called Poire du commandeur.[3] In Chinese it is called Lu mi (露蜜), in Japanes Rumii (ル ミー), Vietnamese, Chanh Pháp.[4]
The fruit resembles a pear in shape, has a thick peel and is not very juicy. Like a citron, it can grow to a formidable size.
Pomum Adami
There is variety of Lumia called Pomme D'Adammo or Adam's apple, and is also included under the name Citrus lumia, according to Risso & Poit, the variety name is pomum adami. Pomme D'Adammo is genetically the same kind but in a rounded form.[5]
Other cultivated varieties of Lumia includes: Bornéo (Indonesia), Balaingue, Bitrouni and Otrodj (Iran).
Origin and Genetics
The most known origin for the Lumia is from the Mediterranean basin. The Lumia is also classified as: Citrus limon var. lumia by Swingle which places it under the taxonomy of lemon, and Citrus medica L. var. lumia that suggests it as similar to citron.
Usually the lumia is referred to as a citron hybrid, because of it's size, thick peel and dryness of pulp. Pomo d'Adamo was also described by Johann Christoph Volckamer as a Cedrato which is Italian for a citron hybrid, whilst Cedro refers to a true citron.[6]

A group of scientists working in the University of Catania, Italy has shown by studying its chromosomes that the Pear lemon was first a hybrid of pommelo and citron, which then hybridized with regular lemon. In University of California, Riverside they call it Citrus × limon L. Burm.f., with conflicting reports if it's acidic or not, suggesting that it's a citron x lemon hybrid.
A chromosomal study by researchers at the University of California found the lumia's DNA composed of pommelo, citron and sour orange DNA.[7]
Georges Gallesio has already reported that Pomme d'Adam is a hybrid with the orange.[8] Others are associating or confusing it with the limetta.[9]
Chemistry
According to a Japanese study of 1996, the albedo extract of the Lumia, was shown to possess the highest inhibitory activity against cyclooxygenase (IC50 = 24 μg/mL), among other citrus studied. Flavedo extract of ripe Lumia inhibited cyclooxygenase to the same degree as the albedo, more than the pulp extract.[10]
