Our latest publication has just been released, on reticulate evolution and asymmetric hybridization in a lovely group of rockferns (genus Asplenium) in the Mediterranean. This study is part of an ongoing collaboration with Jose María Gabriel y Galán at the Universidad Complutense de Madrid, and is our second paper published together!
