}}Virola elongata (syn. Virola theiodora ) is a species of tree in the Myristicaceae family. The tree is native to Panama, Guyana, Brazil (Acre, Amazonas, Mato Grosso, Pará, Rondônia and Roraima), Bolivia, Colombia, Ecuador and Peru.[1][2] It is also found in Suriname.[2] Virola elongata is thin and {{convert|7.5-23|m|abbr=on|sigfig=2}} tall, sometimes {{convert|30|m|abbr=on}} tall.[2] The trunk is about {{convert|43|cm|abbr=on|sigfig=2}} in diameter, cylindrical and has smooth brown and gray bark. The fruit is ellipsoidal to subglobular, {{convert|11–20|mm|abbr=on}} long, {{convert|10–15|m|abbr=on}} in diameter and comes in groups of 40.[2] The tree is found in evergreen forests and in scrub up to {{convert|800|m|abbr=on}} in altitude.[2] The Yanomami people use the powdered resin as an entheogen known as nyakwána which is inhaled or "snuffed" into the nasal cavity, it contains a high concentration of 5-MeO-DMT and DMT.[3] Virola elongata extracts have weak antibacterial activity against Enterococcus faecalis and Staphylococcus aureus.[4]Fruit and seeds{{multiple image| align = left | direction = horizontal | image1 = Virola elongata fruit.jpg | caption1 = Virola elongata fruit | image2 = Virola elongata seeds.jpg | caption2 = Virola elongata seeds }}{{clear left}} References1. ^1 2 {{GRIN | accessdate=2008-04-05}} {{Taxonbar|from=Q7934861}}2. ^1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 {{cite web |url = http://www.plantes-botanique.be/e1-Myristicaceae-Virola-elongata |archive-url = https://archive.is/20070519184701/http://www.plantes-botanique.be/e1-Myristicaceae-Virola-elongata |dead-url = yes |archive-date = 2007-05-19 |title = Plantes et botanique :: Virola elongata |publisher = www.plantes-botanique.be |accessdate = 2008-04-30 |last = |first = }} 3. ^{{cite journal | pmid = 5806312 | year = 1969 | last1 = Agurell | first1 = S | last2 = Holmstedt | first2 = B | last3 = Lindgren | first3 = JE | last4 = Schultes | first4 = RE | title = Alkaloids in certain species of Virola and other South American plants of ethnopharmacologic interest | volume = 23 | issue = 3 | pages = 903–16 | journal = Acta Chemica Scandinavica | doi=10.3891/acta.chem.scand.23-0903}} 4. ^{{Cite journal | url = http://www.scielo.br/pdf/bjid/v10n6/a08v10n6.pdf | title = Antibacterial Activity of Brazilian Amazon Plant Extracts | journal = Brazilian Journal of Infectious Diseases | volume = 10 | issue = 6 | doi = 10.1590/S1413-86702006000600008 | year = 2006 | last1 = Suffredini | first1 = Ivana Barbosa | last2 = Paciencia | first2 = Mateus Luís Barradas | last3 = Varella | first3 = Antonio Drauzio | last4 = Younes | first4 = Riad Naim }} 13 : Entheogens|Virola|Medicinal plants|Flora of Brazil|Flora of Bolivia|Flora of Colombia|Flora of Ecuador|Flora of Guyana|Flora of Panama|Flora of Peru|Flora of Suriname|Flora of Rondônia|Flora of the Amazon |
