Robert Northridge talks us through Horsetails. More than half the world's horsetails grow in Robert's home county of Fermanagh and, by extension, Ireland and the UK. His presentation has pictures of all the Irish species together with several of the hybrids, as well as pictures of key features which are useful in identification.
Robert's book recommendation for Horsetail ID is Britain’s Ferns, Clubmosses, Quillworts, and Horsetails: A Field Guide which can be purchased here: [ Ссылка ]
