British helleborines: an object lesson in plant taxonomy


Date & Time

Date: Friday, 13 March 2020

Time: 7:00 pm - 8:00 pm

With Prof. John Richards, Newcastle University

Join us for a Friday Night Talk on British helleborines.

In the British Isles we have eight species of Epipactis, four of which are outbreeding, pollinated by wasps, and the other four primarily self-fertilize. Our concept of species boundaries differs fundamentally between the two groups. Many of the recent developments in our understanding in the genus result from studies of populations in Northumberland. In several cases there is a sharp incongruity between the findings from DNA and those from morphological analysis which raises interesting philosophical questions.

Professor Richards is Emeritus Professor of Botany at the University of Newcastle. He is Joint County Recorder for Plants for South Northumberland for the BSBI, and is a past President of the Alpine Garden Society.


Friday Night Talks are held at Newcastle University, in Ridley Building room RIDB2.1.65.
