Branched Horsetail
''Equisetum ramosissimum'' , known as branched horsetail, is a species of evergreen horsetail (genus ''Equisetum'', subgenus ''Hippochaete''). It is not the same species as ''Equisetum ramosissimum'' , which is a Synonym (taxonomy), synonym of ''Equisetum giganteum''. Botanists today recognize two subspecies. The type subspecies, ''E. ramosissimum'' subsp. ''ramosissimum'', is native through much of Asia, Europe, and Africa, with an introduced population in the southeast United States. ''E. ramosissimum'' subsp.''debile'', sometimes treated as the separate species ''Equisetum debile, E. debile'', is found in southeast Asia and some Pacific islands. The type subspecies has more obvious branching from the aerial stem than subspecies ''debile''. References Equisetum, ramosissimum Flora of Malta {{fern-stub ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...
