picture info	Equisetum ''Equisetum'' (; horsetail, snake grass, puzzlegrass) is the only living genus in Equisetaceae, a family of ferns, which reproduce by spores rather than seeds. ''Equisetum'' is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests. Some equisetids were large trees reaching to tall. The genus ''Calamites'' of the family Calamitaceae, for example, is abundant in coal deposits from the Carboniferous period. The pattern of spacing of nodes in horsetails, wherein those toward the apex of the shoot are increasingly close together, is said to have inspired John Napier to invent logarithms. Modern horsetails first appeared during the Jurassic period. A superficially similar but entirely unrelated flowering plant genus, mare's tail (''Hippuris''), is occasionally referred to as "horsetail", and adding to confusion, the name "mare's tail" is sometimes ap ...

picture info	Equisetum Hyemale ''Equisetum hyemale'' (commonly known as rough horsetail, scouring rush, scouringrush horsetail and, in South Africa, as snake grass) is a perennial herbaceous vascular plant in the horsetail family Equisetaceae. It is a native plant throughout the Holarctic Kingdom, found in North America, Europe, and northern Asia. Distribution In nature ''Equisetum hyemale'' grows in mesic (reliably moist) habitats, often in sandy or gravelly areas. It grows from between sea level to in elevation. It is primarily found in wetlands, and in riparian zones of rivers and streams where it can withstand seasonal flooding. It is also found around springs and seeps, and can indicate their presence when not flowing. Other habitats include moist forest and woodland openings, lake and pond shores, ditches, and marshes and swamps. Description ''Equisetum hyemale'' has vertical jointed reed-like stalks of medium to dark green. The hollow stems are up to in height. The stems are seldom branched. The ...

	Equisetum Variegatum ''Equisetum variegatum'', commonly known as variegated horsetail or variegated scouring rush, is a species of vascular plant in the horsetail family Equisetaceae. It is native to the Northern Hemisphere where it has a circumpolar distribution. Description It is a variable species with several ecotypes, some of which are distinct subspecies. The stems can grow to 40 cm (occasionally 80 cm) in height but are often much smaller. Some forms have prostrate stems that creep along the ground while other forms grow more erect. The stems are dark blue-green, slender and rough to the touch. They may be unbranched or have branches growing from the base. The stem nodes are covered with a sheath that is marked with a black band and has dark teeth with white edges. The stems are tipped with a small cone, 3–4 mm across, which is usually green with a black, bluntly-pointed tip. Distribution and habitat It has a circumpolar distribution in the northern hemisphere, where it is o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
