Meghalaya is home to the mother of all citrus fruitsNokrek National Park, in the West Garo Hills district of the State of Meghalaya, is home to Citrus Indica (locally known as Memang Narang), or the Wild Orange. This variety is found only in this region of the world.
The Wild Orange was discovered by chance and this led to Nokrek National Park being recognized by UNESCO as a Biosphere Reserves in May 2009. Nokrek National Park has a ‘National Citrus Gene Sanctuary’
“This wild orange plant is likely one of the ancestors of today's cultivated citrus fruits, if not the main one. It is considered to be the most "primitive" citrus. It can be used as a citrus rootstock for cultivating citrus. Recent searches of the plant's reported home range confirmed its presence only in Meghalaya, where it grows in the Garo Hills.” Source
