Equisetum sylvaticum (Wood Horsetail)
A deciduous, colony-forming herb which generally grows on deep, mildly acidic, often peaty soils that are kept permanently damp by flushing. It occurs on the lower slopes of mountain valleys, steep streamsides, wet ledges and open flushes, beside lakes and on the edges of drainage ditches. It also occurs on wet road verges and railway embankments. 0-850 m (Breadalbanes, Mid Perth).
There is little evidence of a decline in upland areas since the 1962 Atlas. The decline in the British lowlands was already apparent then, and has continued.
Circumpolar Boreo-temperate element.
Inland rock (quarries, cliffs, screes)
