Horsetails

Equisetaceae

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 and 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.
