쇠뜨기-[정명] Equisetum arvense L.
국표에 없다.
Equisetum arvense, the field horsetail or common horsetail, is an herbaceous perennial plant in the Equisetidae (horsetails) sub-class, native throughout the arctic and temperate regions of the Northern Hemisphere. It has separate sterile non-reproductive and fertile spore-bearing stems growing from a perennial underground rhizomatous stem system. The fertile stems are produced in early spring and are non-photosynthetic, while the green sterile stems start to grow after the fertile stems have wilted and persist through the summer until the first autumn frosts. It is sometimes confused with mare's tail, Hippuris vulgaris.
Rhizomes can pierce through the soil up to 6 feet (1.8 m) in depth. This allows this species to tolerate many conditions and is hard to get rid of even with the help of herbicides.
Taxonomy
Linnaeus described field horsetail with the binomial Equisetum arvense in his Species Plantarum of 1753. The specific epithet arvense is from the Latin "arvum", meaning "ploughed", referencing the growth of the plant in arable soil or disturbed areas. The common name "common horsetail" references the appearance of the plant that when bunched together appears similar to a horse's tail.
Many species of horsetail have been described and subsequently synonymized with E. arvense. One of these is E. calderi, a small form described from Arctic North America.
Names
Some other common names include "horse pipes", "bottle-brush", "snake-grass", "devil's-guts", "horsetail fern", "pine-grass", "meadow-pine", and "foxtail-rush". It is also known as "marestail", primarily in the UK, but this common name is also used for the flowering aquatic plant Hippuris vulgaris and the common North American weed Erigeron canadensis.
