Equisetum ramosissimumDesf., known as branched horsetail, [2] is a species of evergreen horsetail (genus Equisetum , subgenus Hippochaete). [1]
Horsetail with untidy branches from the lower parts (which may be prominent or not apparent), with or without main upright stems, able to form a colony from underground roots. Rocky ground tends to constrict root-spread and favours a bushy appearance, unrocky ground favours more slender plants arising from spreading roots, and trampling or cutting affects shape. The general colour may have a blue-grey tinge, sometimes quite strongly, the stem when broad is fairly hollow and compressible, narrower branches rather tough and wiry, the stem ridges are conspicuous (not fine and obscure) and slightly rough. The fertile cones when visible are from stems arising as part of the main plant (not arising early separately) and have pointed cone tips (sometimes obscure).
Habitat: Damp places (stream banks, moist meadows, watered edges, path edges) and shingle. [3] [4] [5]
Equisetum is the only living genus in Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds.
Equisetum fluviatile, the water horsetail or swamp horsetail, is a vascular plant that commonly grows in dense colonies along freshwater shorelines or in shallow water in ponds, swamps, ditches, and other sluggish or still waters with mud bottoms. It is a perennial herbaceous species, growing 30–100 cm tall with erect dark green stems 2–8 mm in diameter, smooth, with about 10–30 fine ridges. At each joint, the stem has a whorl of tiny, black-tipped scale leaves 5–10 mm long. Many, but not all, stems also have whorls of short ascending and spreading branches 1–5 cm long, with the longest branches on the lower middle of the stem. The side branches are slender, dark green, and have 1–8 nodes with a whorl of five scale leaves at each node. The water horsetail has the largest central hollow of the horsetails, with 80% of the stem diameter typically being hollow.
Equisetidae is one of the four subclasses of Polypodiopsida (ferns), a group of vascular plants with a fossil record going back to the Devonian. They are commonly known as horsetails. They typically grow in wet areas, with whorls of needle-like branches radiating at regular intervals from a single vertical stem.
Equisetum sylvaticum, the wood horsetail, is a horsetail native to the Northern Hemisphere, occurring in North America and Eurasia. Because of its lacy appearance, it is considered among the most attractive of the horsetails.
Lycopodium clavatum is the most widespread species in the genus Lycopodium in the clubmoss family.
Mentha longifolia, also known as horse mint, brookmint, fillymint or St. John's horsemint, is a species of plant in the family Lamiaceae. It is native to Europe excluding Britain and Ireland, western and central Asia, and northern and southern Africa.
Equisetum giganteum, with the common name southern giant horsetail, is a species of horsetail native to South America and Central America, from central Chile east to Brazil and north to southern Mexico.
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.
Equisetum palustre, the marsh horsetail, is a plant species belonging to the division of horsetails (Equisetopsida). It is widespread in cooler regions of North America and Eurasia.
Equisetum pratense, commonly known as meadow horsetail, shade horsetail or shady horsetail, is a widespread horsetail (Equisetophyta) fern. Shade horsetail can be commonly found in forests with tall trees or very thick foliage that can provide shade and tends to grow closer and thicker around streams, ponds and rivers. The specific epithet pratense is Latin, meaning pasture or meadow dwelling.
Equisetum telmateia, the great horsetail or northern giant horsetail, is a species of Equisetum (puzzlegrass) with an unusual distribution, with one subspecies native to Europe, western Asia and northwest Africa, and a second subspecies native to western North America. The North American subspecies is often simply but ambiguously called "giant horsetail", but that name may just as well refer to the Latin American Equisetum giganteum and Equisetum myriochaetum.
Equisetum laevigatum is a species of horsetail in the family Equisetaceae. It is known by the common names smooth horsetail and smooth scouring rush. This plant is native to much of North America except for northern Canada and southern Mexico. It is usually found in moist areas in sandy and gravelly substrates. It may be annual or perennial. It grows narrow green stems sometimes reaching heights exceeding 1.5 meters. The leaves at the nodes are small, scale-like brownish sheaths and there are occasionally small, spindly branches. The stems are topped with rounded cone-shaped sporangia.
Juncus acutus, the spiny rush, sharp rush or sharp-pointed rush, is a flowering plant in the monocot family Juncaceae. It is native to the Americas, Northern and Southern Africa, Western and Southern Europe and West Asia, and is found in a variety of wet habitats, such as bogs, fens, meadows, and salt marshes, and along the edges of ponds and lakes.
Equisetum hyemale is a perennial herbaceous fern in the horsetail family Equisetaceae. It is a native plant throughout the Holarctic Kingdom, found in North America, Europe, and northern Asia.
Sambucus racemosa is a species of elderberry known by the common names red elderberry and red-berried elder.
Bromus madritensis is a species of brome grass known by the common name compact brome. The specific epithet madritensis refers to Madrid, Spain. It has a diploid number of 28.
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.
Equisetum scirpoides Michx., Fl. Bor.-Amer. 2: 281 (1803). 2 n = 216.The smallest of the currently occurring representatives of the genus Equisetum (horsetail).
Urtica gracilis, commonly known as the slender nettle, tall nettle, or American stinging nettle, is a perennial plant plant without woody stems that is well known for the unpleasant stinging hairs on its leaves and stems. It is native to much of the North America from Guatemala northwards and temperate areas of South America. It is easily confused with the visually very similar Eurasian species Urtica dioica and is still listed in some resources as a subspecies of this plant. However, genetic analysis and experiments show that they are genetically distinct.
Equisetum ramosissimum var. huegelii, with synonyms including Equisetum debile and Equisetum huegelii, is a variety of Equisetum ramosissimum, a plant in the family Equisetaceae, found in parts of tropical Asia and China.
