Lycophytes, which appeared some 420 million years ago, are the oldest existing vascular plant group. For a long time, they dominated the forests of the ancient world, and took a broad range of forms, including several arborescent species more than 30 metres tall. Mass extinctions and competition with other plant groups led to the disappearance of these large specimens, and the only remaining members of the group are herbaceous forms no more than a few centimetres tall. These modern species are now being used as a model to study the evolution of terrestrial plants. © D. Barthélémy, CIRAD
