New flower of Staphylea preserved in amber from Miocene of Simojovel de Allende, Chiapas, Mexico.

The amber deposits from Simojovel de Allende, Chiapas, Mexico are one of the most important resin deposits from the Cenozoic in the world; however paleontological studies are few for this zone, especially those related with plants. Recently, a new fossil record of a flower Staphylea (Staphyleaceae) was added to the other reports in the same deposits. This flower is bisexual, small, pedicelled, pentamerous, with differentiated perianth and superior ovary, furthermore the presence of stamens with pubescent filaments suggests a major morphologic similarity with S. bumalda and S. yuanjiangensis species that nowadays grow in Asia and template zones. The presence of Staphylea in the Miocene of the southern Mexico is evidence of the large history of floristic elements that form the Mexican vegetation that can be explained with the Boreotropical Hypothesis.
