Limu, otherwise known as rimu, remu or {{okina}}imu (from Proto-Austronesian *limut){{cite web|url=https://acd.clld.org/cognatesets/30638#2/-10.7/151.9|title=*limut: moss, algae|last1=Blust|first1=Robert|author-link1=Robert Blust|last2=Trussel|first2=Stephen|website=Austronesian Comparative Dictionary|date=2010|publisher=Max Planck Institute for Evolutionary Anthropology|access-date=7 December 2022}} is a general Polynesian term for edible plants living underwater, such as seaweed, or plants living near water, like algae.{{Cite web|url=http://www.temarareo.org/PPN-Limu.html|title=Limu: Seaweed, mosses and algae of polynesia|website=Te Māra Reo: The Language Garden|year=2022|publisher=Benton Family Trust}}{{Cite web|url=http://wehewehe.org/gsdl2.85/cgi-bin/hdict?e=q-11000-00---off-0hdict--00-1----0-10-0---0---0direct-10-ED--4-------0-1lpm--11-haw-Zz-1---Zz-1-home-limu--00-3-1-00-0--4----0-0-11-00-0utfZz-8-00&a=d&d=D11135|title=Nā Puke Wehewehe ʻŌlelo Hawaiʻi|website=wehewehe.org|access-date=2019-04-26}} In Hawaii, there are approximately one hundred names for kinds of limu, sixty of which can be matched with scientific names.{{Cite web | url = http://www.botany.hawaii.edu/ethnobotany/pdf/Limu-092107AKC.pdf | title = Limu | accessdate = 2008-09-05 | first = Isabella | last = Aiona Abbott

Uses

Several species of limu are used as food throughout Polynesia and is typically eaten raw as accompaniment to meals, usually fish.

In Hawaii, limu was seen as a major component of the Hawaiian diet alongside fish and poi. Hawaiians cultivated several varieties of seaweed for food as well as to feed fish farmed within fish ponds. As many as 75 types of limu were used for food, more than the 35 used in Japanese cuisine, which is also well known for its use of seaweed. In modern times, limu is often used as a condiment, typically in raw fish dishes such as poke.{{Cite web|url=http://www.hawaii.edu/gk-12/evolution/pdfs/algae.uses.highschool.pdf|title=Got limu? Uses for algae in Hawaii and beyond|last=Spalding|first=Heather|website=University of Hawaii|access-date=April 25, 2019}}

Limu was used in hoʻoponopono, the ancient Hawaiian process of conflict resolution. Injured and accused parties gathered to pray, seek forgiveness and eat {{lang|haw|limu kala}} leaves as a symbol of reconciliation.{{Cite web|url=https://www.mauimagazine.net/the-lure-of-limu/|title=The Lure of Limu|last=Wianecki|first=Shannon|date=2010-03-01|website=mauimagazine.net|language=en-US|access-date=2019-04-22}} It is also used in traditional hula attire{{Cite web|url=https://www.papahanaumokuakea.gov/news/new_species_algae.html|title=New Algae Species Discovered in Hawaii's Deep Waters|website=www.papahanaumokuakea.gov|access-date=2019-04-26}} and as medicine.{{Cite book|url=http://scholarspace.manoa.hawaii.edu/handle/10125/42229|title=Economic seaweeds of Hawaii and their food value.|last=Reed|first=Minnie|date=1907|publisher=Washington, U.S. Government Printing Office|hdl=10125/42229}}

Due to the shape of its foliage, the Maori also applied the name {{lang|mi|rimu}} to the native tree Dacrydium cupressinum.

Types

Limu comes from multiple genera{{Cite web|url=http://www.hawaii.edu/reefalgae/publications/ediblelimu/|title=Edible Limu of Hawaii|website=www.hawaii.edu|access-date=2019-04-22}}

Threats

Limu has become increasingly difficult to find because of over-picking, pollution, and urban development,{{Cite web|url=https://www.hawaiipublicradio.org/post/cultivating-future-hawaiian-seaweed|title=Cultivating a Future for Hawaiian Seaweed|last=Hiraishi|first=Ku`uwehi|website=www.hawaiipublicradio.org|date=12 April 2018 |language=en|access-date=2019-04-26}} especially construction in watersheds. Many important kinds of limu grow best in brackish water where fresh water empties into the sea. Another threat to limu is the spread of marine alien invasive species, such as members of the genus Kappaphycus (smothering seaweed), Gracilaria salicornia (gorilla ogo), Avrainvillea amadelpha (leather mudweed), Hypnea musciformis (hook weed) and Acanthophora spicifera (prickly seaweed).{{Cite web|url=https://dlnr.hawaii.gov/ais/invasivealgae/|title=Invasive Algae|date=2013-12-09|website=Aquatic Invasive Species|language=en|access-date=2019-04-22}}
