Twig Key

John Poland, Chair of BSBI's Publications Committee and co-author of the celebrated Vegetative Key to the British Flora, has been working for some years on a new book and this September, the Field Key to Winter Twigs will be published. John says "This guide hopes to make winter botany fun! The book is a fully illustrated A5 softback with detailed keys, stunning full colour photographs and diagnostic B&W line illustrations, making winter ID easy for native and planted taxa". Click on the link to download the Twig Key flyer.

The pre-publication offer, available to both BSBI members and non-members, has now opened.

Use the links below to purchase your copy for £15. This includes P&P to Britain, Northern Ireland and the Channel Islands. We regret that, in order to cover postal costs, we will have to charge a further £4 P&P to the Republic of Ireland and £6.50 to the rest of the world. The secure PayPal facility below can be used whether or not you have a PayPal account, and we've added options for various P&P rates and so you can buy multiple copies if required.
