horsetail


horsetail,

any plant of the genus Equisetum [Lat.,=horse bristle], the single surviving genus of a large group (Equisetophyta) of primitive vascular plants. Like the ferns and club mosses, relatives of the living horsetails thrived in the Carboniferous period (when they contributed to coal deposits); the group as a whole is now considered relictual. Horsetails have whorls of small scalelike leaves around a hollow, jointed stem that is green and carries on photosynthesis. They reproduce by an alternation of generations (see reproductionreproduction,
capacity of all living systems to give rise to new systems similar to themselves. The term reproduction may refer to this power of self-duplication of a single cell or a multicellular animal or plant organism.

) similar to that of the ferns; in some horsetails, special nongreen shoots have at their tops strobili (see conecone

) that bear the spores. Fossil evidence indicates that many extinct horsetails were treelike and attained a far greater size than do living types, although the stems of a sprawling tropical American species (E. giganteum) grows to more than 30 ft (9.1 m) in length. Other species, mostly under 3 ft (91 cm), are found in all temperate and tropical regions except New Zealand and Australia; the common types of North America and Eurasia are E. arvense in drier habitats and E. hyemale, the scouring rush, in moist and wooded areas. The latter was formerly utilized for scouring purposes and it is still included in some scouring and abrasive powders; its typical coarse texture is due to the presence of silica. Other horsetails have been used for home remedies. Horsetails are classified in the division EquisetophytaEquisetophyta
, small division of the plant kingdom consisting of the plants commonly called horsetails and scouring rushes. Equisetum, the only living genus in this division, is descended evolutionarily from tree-sized fossil plants.

A strange plant that starts with having fertile off-white beige stalks with scaly fingers on top in the spring, which wither and get replaced by non-fertile green stems resembling horse tails.
