There is debate over the existence of Quercus cerris x Q. robur hybrids. Such intermediates have been documented in the UK with characteristic Q. cerris features (persistent stipules and pubescence), but with a more Q. robur-like leaf shape. These possible hybrids may simply be Q. cerris when considering its variable leaf morphology, and also the relatively long phylogenetic distance between these two Quercus species, meaning a lower likelihood of a such a hybrid arising. An MSc project at Reading University is attempting to establish their true identity, and requires intermediate specimens for morphological and molecular analysis. The student would be extremely thankful to hear from any members who have any information about such specimens. Please contact Kevin McGinn, k.j.mcginn@student.reading.ac.uk, for more details.
