eFLOWER is a collaborative, international research project aimed at answering key questions on the evolution of flowers.

• What were flowers like in deep nodes of the angiosperm tree?
• Which floral innovations are linked with major increases in diversification rates?
• How are floral characters correlated with one another?
• To what extent has floral diversification been driven by pollination?
• Where do fossil flowers fit on the phylogeny of extant angiosperms?

To answer these questions, we are building a database of floral traits for a large sample of angiosperm species. eFLOWER is currently coordinated by a team of researchers from France and Austria.
