Citron
The citron ("Citrus medica") is a large fragrant citrus fruit with a thick rind. It is one of the original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial hybridization. Though citron cultivars take on a wide variety of physical forms, they are all closely related genetically. It is used widely in Asian cuisine, and also in traditional medicines, perfume, and for religious rituals and offerings. Hybrids of citrons with other citrus are commercially prominent, notably lemons and many limes.
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.
