Ferns & Horsetails
For information about what to record for flora, see our guidance page.
Horsetails are the relicts of an ancient family that once included tree-sized species, the fossils of which formed huge coal deposits.
Underground rhizomes produce numerous aerial stems; the stems and branches appear jointed and there is a ring of sheaths modified from leaves at each node. The size of the hollows inside a stem, the appearance of the sheaths and the number of stem ridges/sheaths are all used in identification. Cut through a stem-internode with your thumbnail to check photograph the arrangement of hollows in the cross-section.
The spores are borne on cones at the top of the stems - sometimes on a separate brown or whitish stem.
