"Keying out" is a daunting but essential skill for anyone interested in Botany.

This one-day introduction will explain how dichotomous keys work, how to find your way around them, and will guide you through their use and application - and their limitations.

We will work mainly from The Vegetative Key to the British Flora by Poland and Clements (with reference to Rose, and Stace) and the FSC's Tree Name Trail, a copy of which is yours to keep.

This practical course will take us outside as much as possible. Based in Bushy Park.
