Symplocos kowalewskii - the largest amber-preserved flower

First described over 150 years ago as Stewartia kowalewskii, a corolla preserved in amber from at least 34 million years ago was reanalysed and reclassified by researchers. Measuring 28 mm in diameter, it is the largest-known fossilised flower to be preserved in amber, nearly three times the size of other preserved flowers. The analysis of pollen extracted from the anthers of the flower inclusion, revealed strong affinities to Asian species of Symplocos. Renamed Symplocos kowalewskii, the fossilised flower represents the first record of Symplocaceae from Baltic amber.
