Lumia (citrus)
A recent genomic analysis of several species commonly called 'lemons' or 'limes' revealed that the various individual lumias have different genetic backgrounds. The 'Hybride Fourny' was found to be an F1 hybrid of a citron- pomelo cross, while the 'Jaffa lemon' was a more complex cross between the two species, perhaps an F2 hybrid. The Pomme d'Adam arose from a citron-micrantha cross, while two other lumias, the ‘Borneo’ and ‘Barum’ lemons, were found to be citron-pomelo-micrantha mixes.
Rangpur (fruit)
"Citrus" × "limonia" was introduced into Florida in the late nineteenth century by Reasoner Brothers of Oneco, who obtained seed from northwestern India. Though often described as a lemon hybrid, genomic analysis has shown it to be an F1 hybrid of a female citron ("Citrus medica") and a male mandarin orange ("Citrus reticulata").
