According to ancient literature, this is the 'true Kadam' which is associated with Lord Krishna in Vrindavana, rather than the well-known tree Neolamarckia cadamba. But this is definitely a case of mistaken identity. Neolamarckia cadamba is not found naturally in the hot, dry Vrindavana region. M. parviflora is not only native to the Vrindavana forests but is their dominant tree. Interestingly, M. parviflora are still found almost everywhere in Vrindavana.[5]
