	Equisetum sylvaticum
		Fasset (1944) studied the occurrence of scabrosity in mass collections from Maine to Alaska, and found that there was complete intergradation from scabrous to glabrous, and that there was a cline of increasing scabrosity across the continent from Maine to Alaska (see Table).
		Fassett reported that even among the stems from one rhizome there can be variation in amount of scabrosity.

	Equisetum species, The Horsetails and Scouring Rushes
		Equisetum are still unknown in North America, but they should be sought, especially north of 45° N latitude.
		Because Equisetum are rarely encountered as lone stems in the field, a quick survey of the clump is sufficient to determine subgenus.
		Equisetum is the sole surviving genus of a complex group of primitive plants which covered the planet during the Carboniferous period more than 300 million years ago.

	Horsetail - Wikipedia, the free encyclopedia
		The horsetails are vascular plants, comprising 15 species of plants in the genus Equisetum.
		The name horsetail arose because it was thought that the stalk resembled a horse's tail; the name Equisetum is from the Latin equus, "horse", and seta, "bristle".
		The superficially similar flowering plant, Mare's tail (Hippuris vulgaris), unrelated to the genus Equisetum, is occasionally misidentified and misnamed as a horsetail.

		Equisetum arvense is a herbaceous plant up to fifty centimetres high, with a long underground rhizome and two distinct types of aerial stems, both articulated into nodes and internodes.
		Equisetum arvense is also used in traditional medicine as a diuretic, haemostat and particularly as a source of mineral salts because of its high content (up to 15%) of silicic acid, soluble in water.
		Equisetum is restorative to damaged pulmonary tissue after pulmonary tuberculosis and other lung disease, as the silicic acid is said to stabilise the scar tissue.

	Equisetum in Flora of North America @ efloras.org
		Equisetum occurs in moist places such as riverbanks, lakeshores, roadsides, ditches, seepage areas, meadows, marshes, and wet woodlands.
		Aerial stems of Equisetum vary considerably in habit and appearance, even on individual plants, because of environmentally induced modifications affecting height and branching.
		Reticulation in Equisetum is summarized in the reticulograms, which show the known and expected hybrids in North America.

	botanical.com - A Modern Herbal \| Horsetails - Herb Profile and Information
		The class includes only a single genus, Equisetum, the name derived from the Latin words equus (a horse) and seta (a bristle), from the peculiar bristly appearance of the jointed stems of the plants, which have also earned them their popular names of Horsetail, Bottle-brush and Paddock-pipes.
		Though mostly inhabitants of watery places, flourishing where they can lodge their perennial roots in water or string clay which holds the wet, the Equisetums will grow in a garden near water, under a wall, or in the shade and will spread rapidly.
		It is readily recognized by the elegant appearance of the whorls of recurved branches, generally twelve or more branches to a whorl, which are very slender, about 5 inches long, quadrangular and beset by several secondary whorls so that the plant resembles a miniature pine tree.

		This gem is called Equisetum sylvaticum, one stem of which is represented in the accompanying figure.
		Equisetum sylvaticum is a British plant, very scarce generally, but plentiful enough in some districts.
		By many this will be considered more beautiful than sylvaticum, for the slender branches divide and subdivide into the most hair-like ramifications; indeed, it looks as if constructed of hair, but in a manner that would be impossible to human fingers even if only in imitation of its beauty.

		Equisetum ×mildeanum Rothm., the hybrid between Equisetum pratense Ehrh.
		and Equisetum sylvaticum L. was described by Rothmaler (1951) based upon material that he collected on the baltic isle of Rügen in northeastern Germany.
		Because of the morphological plasticity that characterizes horsetail taxa in general, it is indispensable to check the quality of the spores in order to separate mere growth forms from true hybrids.

	Horsetail - CreationWiki
		A Horsetail is any plant of the genus Equisetum the single surviving genus of a large group of primitive vascular plants.
		It is named the "horsetail" because the stalk resembles a horse's tail.
		The name Equisetum came from the Latin roots equus, meaning "horse" and seta, meaning "bristle." It doesn't make flower, but produces spores like the fern.
