| − | '''''Acorus''''' is a [[genus]] of [[monocot]] [[flowering plant]]s. This genus was once placed within the family [[Araceae]] (aroids), but more recent classifications place it in its own family '''Acoraceae''' and order '''Acorales''', of which it is the sole genus of the oldest surviving line of monocots. The exact relationship of Acorus to other monocots, however, is still debated by scientists. Some studies indicate that it is placed in a lineage (the order Alismatales), that also includes aroids (Araceae), [[Tofieldiaceae]], and several families of aquatic monocots (e.g., Alismataceae, [[Posidoniaceae]]). Common names include '''Calamus''' and '''[[Sweet Flag]]'''. It is known as ''vasambu'' in [[Tamil language]].
| + | ==Cultivation== |
| − | | + | {{edit-cult}}<!--- Type cultivation info below this line, then delete this entire line --> |
| − | The name 'acorus' is derived from the Greek word 'acoron', a name used by [[Dioscorides]], which in turn was derived from 'coreon', meaning 'pupil', because it was used in [[herbalism|herbal medicine]] as a treatment for [[inflammation]] of the [[eye]].
| |
| − | | |
| − | The genus is native to [[North America]] and northern and eastern [[Asia]], and [[naturalised]] in southern Asia and [[Europe]] from ancient cultivation. The known wild populations are [[diploid]] except for some [[tetraploid]]s in eastern Asia, while the cultivated plants are sterile [[triploid]]s, probably of [[hybrid]] origin between the diploid and tetraploid forms.
| |
| − | | |
| − | ==Taxonomy==
| |
| − | | |
| − | Although the family Acoraceae was originally described in 1820, since then ''Acorus'' has traditionally been included in Araceae in most classification systems, as in the [[Cronquist system]]. The family has recently been resurrected as molecular systematic studies have shown that ''Acorus'' is not closely related to Araceae or any other [[monocot]] family, leading plant systematists to place the genus and family in its own order. This placement currently lacks support from traditional plant morphology studies, and some taxonomists still place it as a subfamily of Araceae, in the order [[Alismatales]].
| |
| − | | |
| − | The [[APG II]] system recognizes order Acorales, distinct from the Alismatales, and as the [[sister group]] to all other monocots.
| |
| − | | |
| − | ==Characteristics== | |
| − | | |
| − | [[Image:Acorus-calamus2.jpg|thumb|left|Sweet Flag - leaves]]
| |
| − | These grasslike evergreen plants are '''hemicryptophytes''', (i.e. perennial plants of which the overwintering buds are at the soil surface) or '''geophytes''' (i.e. the overwintering buds are found underground, usually attached to a bulb, corm, tuber, etc.). Their natural habitat is at the waterside or close to marshes, often found with reedbeds.
| |
| − | | |
| − | The inconspicuous [[flower]]s are arranged on a lateral [[spadix]] (a thickened, fleshy axis). Unlike aroids, there is no [[spathe]] (large bract, enclosing the spadix). The spadix is 4-10 cm long and is enclosed by the foliage. The bract can be ten times longer than the spadix. The [[leaf|leaves]] are linear with entire margin.
| |
| − | | |
| − | The parallel-veined leaves of some species contain ethereal oils that give a sweet scent when dried. Fine-cut leaves used to be strewn across the floor in the Middle Ages, both for the scent, and for presumed efficacy against [[pest (animal)|pest]]s.

| − | | |
| − | == Species ==
| |
| − | In older literature and on many websites, there is still much confusion, with the name ''Acorus calamus'' equally but wrongfully applied to ''Acorus americanus''.
| |
| − | | |
| − | The genus includes :
| |
| − | *''[[Acorus americanus]] (Raf.) Raf. '' (formerly known as ''A. calamus'' var. ''americanus'') - '''American Sweet Flag'''; fertile diploid (2''n'' = 24); occurring in Alaska, Canada and northern USA. Diploid plants in [[Siberia]] and temperate Asia may also belong here, but have not been fully investigated ([http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=222000002]). Recently recognised as a distinct species by the ''Flora of North America''.
| |
| − | *''[[Acorus calamus]]'' L. - '''Common Sweet Flag'''; sterile triploid (3''n'' = 36); probably of cultivated origin. It is native to [[Europe]], temperate [[India]] and the [[Himalaya]]s and southern Asia, widely cultivated and naturalised elsewhere.
| |
| − | *''[[Acorus gramineus]]'' Sol. ex Aiton - '''Japanese Sweet Flag''' or '''Grassy-leaved Sweet Flag'''; fertile diploid (2''n'' = 18); occurring in the Himalayas to Japan, Myanmar, Thailand, the Philippines.
| |
| − | *''[[Acorus triqueter]]'' Turcz. ex Schott (syn. ''A. calamus'' var. ''angustatus'') - fertile tetraploid (4''n'' = 48); occurring in eastern Asia, Japan and Taiwan.
| |
| − | *''[[Acorus latifolius]]'' Z.Y.Zhu : native to China
| |
| − | *''[[Acorus xiangyeus]]'' Z.Y.Zhu : native to China

| − | [[Image:Acorus calamus illustration.jpg|thumb|right|Sweet Flag (drawing)]]
| |
| − | | |
| − | ''Acorus'' from Europe, [[China]] and Japan have been planted in the [[United States]].
| |
| − | | |
| − | == Chemistry ==
| |
| − | Both triploid and tetraploid calamus contain [[asarone]], but diploid does not contain any. Asarone is a possible precursor in the synthesis of the psychedelic phenethylamine TMA-2. The chemical itself is reportedly without activity at doses up to 70 mg.
| |
| − | | |
| − | == Regulations ==
| |
| − | Calamus and products derived from calamus (such as its oil) were banned in 1968 as food additives and medicines by the [[United States]] [[Food and Drug Administration]].
| |
| − | | |
| − | == Usage ==
| |
| − | Calamus has been an item of trade in many cultures for thousands of years. Calamus has been used medicinally for a wide variety of ailments.
| |
| | | | |
| − | In antiquity in the Orient and Egypt, the rhizome was thought to be a powerful aphrodisiac. In Europe ''Acorus calamus'' was often added to wine, and the root is also one of the possible ingredients of [[absinthe]]. Among the northern Native Americans, it is used both medicinally and as a [[stimulant]]; in addition, the root is thought to have been used as an [[entheogen]] among the northern Native Americans. In high doses, it is [[Psychedelics, dissociatives and deliriants|hallucinogenic]]; Calamus has been used as a "street drug alternative".

| − | == Cultural symbolism == | + | ===Pests and diseases=== |
| − | The calamus has long been a symbol of male love. The name is associated with a Greek myth: [[Kalamos]], a son of the river-god [[Maeander]], who loved [[Karpos]], the son of [[Zephyrus]] and [[Chloris]]. When Karpos drowned, Kalamos was transformed into a reed, whose rustling in the wind was interpreted as a sigh of lamentation.
| + | {{edit-pests}}<!--- Type pest/disease info below this line, then delete this entire line --> |
| | | | |
| − | The plant was a favorite of [[Henry David Thoreau]] (who called it sweet flag), and also of [[Walt Whitman]], who added a section called ''The Calamus Poems'', celebrating the love of men, to the third edition of ''[[Leaves of Grass]]'' (1860). In the poems the calamus is used as a symbol of love, lust, and affection. It has been suggested that the symbology derives from the visual resemblane of the reed to the erect human penis.
| + | ==Species== |
| | + | <!-- This section should be renamed Cultivars if it appears on a page for a species (rather than genus), or perhaps Varieties if there is a mix of cultivars, species, hybrids, etc --> |
| | | | |
| − | The name ''Sweet Flag'' refers to its sweet scent (It has been used as a strewing herb) and the wavy edges of the leaves which are supposed to resemble a fluttering flag.

| − | ==Etymology of the word Calamus==
| + | <gallery> |
| − | [[Cognate]]s of the [[Latin]] word ''Calamus'' are found in both [[Greek language|Greek]] (''[[kalamos]]'', meaning "reed") and [[Sanskrit]] (''kalama'', meaning "reed" and "pen" as well as a sort of rice) — strong evidence that the word is older than all three languages and exists in their parent language, [[Proto-Indo European]]. The [[Arabic language|Arabic]] word ''qalam'' (meaning "pen") is likely to have been borrowed from one of these languages in antiquity, or directly from Indo-European itself.
