. In 2016, Poinar announced the discovery of a new plant species that is a 45-million-year-old relative of coffee he found in amber. Named '' Strychnos electri'', after the Greek word for amber (electron), the flowers represent the first-ever fossils of an asterid. In 2017, Poinar published a paper describing a fossilized flower and its tentative
