What is Tutu (plant)?
{{redlinks|date=June 2020}} '''Tutu''' is a common name of [[Māori people|Māori]] origin for plants in the genus ''[[Coriaria]]'' ([[Coriaria]]ceae) found in [[New Zealand]]. [[File:Coriaria arborea 11.JPG|thumb|right|''Coriaria arborea'', a '''tutu''' plant.]] Six New Zealand native species are known by the name: *''[[Coriaria angustissima]]'' *''[[Coriaria arborea]]'' *''[[Coriaria lurida]]'' *''[[Coriaria plumosa]]'' *''[[Coriaria pteridoides]]'' *''[[Coriaria sarmentosa]]'' They are [[shrub]]s or [[tree]]s; some are [[Endemism|endemic]] to New Zealand. Most of the plant parts are [[poison]]ous, containing the [[neurotoxin]] [[tutin (toxin)|tutin]]. Both the seeds and sap of tutu are highly poisonous, resulting in many [[cattle]] deaths in the early days of European settlement. After removing the poisonous seeds, Māori people prepared a drink from the fruit, which they often boiled with a type of [[seaweed]] ('''rimu'''). The resulting [[jelly]] ('''rehia''') was then fermented.<ref>{{cite web|url=http://www.teara.govt.nz/en/shrubs-and-small-trees-of-the-forest/page-3|work=Te Ara Encyclopedia of New Zealand|title=Broadleaf colonisers - Shrubs and small trees of the forest|accessdate=5 April 2013}}</ref> [[Honey]] containing tutin can be produced by [[bee|honey bee]]s feeding on [[honeydew]] produced by [[Plant sap|sap]]-sucking vine [[Treehopper|hopper]] insects (''[[Scolypopa australis]]''<ref>{{cite web|url=http://www.environment.gov.au/biodiversity/abrs/online-resources/fauna/afd/taxa/Scolypopa_australis|title=Australian Faunal Directory|accessdate=5 April 2013|archive-date=5 October 2012|archive-url=https://web.archive.org/web/20121005190459/http://www.environment.gov.au/biodiversity/abrs/online-resources/fauna/afd/taxa/Scolypopa_australis|url-status=dead}}</ref>) feeding on tutu.<ref>[http://www.nzfsa.govt.nz/animalproducts/publications/info-pamphlet/bee-products/toxic-honey.htm Background on toxic honey], New Zealand Food Safety Authority</ref> The toxin is in the sap of the Tutu bush.
