New images of the largest fossilized flower to be discovered in amber have recently been published in the journal Scientific ReportsEstablished in 2011, <em>Scientific Report</em>s is a peer-reviewed open-access scientific mega journal published by Nature Portfolio, covering all areas of the natural sciences. In September 2016, it became the largest journal in the world by number of articles, overtaking <em>PLOS ON</em>E.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>Scientific Reports. The flower, measuring 28 millimeters across, is nearly three times larger than other preserved flowers.

The fossilized flower, encased in amber from the Baltic forests of Northern Europe and dating back almost 40 million years, is believed to be from an ancient flowering evergreen plant referred to as Stewartia kowalewskii.

Eva-Maria Sadowski and Christa-Charlotte Hofmann reanalyzed the exceptionally large fossilized flower, which was originally described and named in 1872. The flower is dated to the Late Eocene, from between 38 million to 33.9 million years ago.

The authors extracted pollen from the sample and their analysis suggests that the flower is closely related to the Asian speciesA species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>species of Symplocos. The authors propose a new name for the flower of Symplocos kowalewskii.

The authors propose that the rare size of S. kowalewskii is likely from a large resin outpouring that would have encased the flower. The properties of the resin would have helped to prevent organisms from growing on the flower and causing damage, they add.
