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.
Genoplesium citriodorum
The lemon scented midge orchid was first formally described in 1991 by David Jones and Mark Clements who gave it the name "Genoplesium citriodorum" and published the description in "Australian Orchid Research". In 2002, Jones and Clements changed the name to "Corunastylis citriodora". The specific epithet ("citriodorum") is derived from the Latin words "citrea" meaning "the citron-tree" and "odor" meaning "smell", referring to the strongly lemon-scented flowers.
