Equisetum hyemale (Rough Horsetail)
A slow-growing, evergreen herb forming colonies of shoots from branching rhizomes. It prefers heavy soils derived from sand or clay which are permanently moist and have a high mineral and silica content. It is usually found in shaded open woodland beside streams and rivers, but also grows in base-rich moorland flushes and sand dunes. 0?610 m (Glen Lyon, Mid Perth).
Most losses of E. hyemale occurred before 1930, probably due to drainage and an increase in grazing and trampling of riverbanks by livestock. However, many new sites have been discovered since the 1962 Atlas.
