Talk:Pongamia

Names in other languages
There are a series of common names for this tree. Adding every alternate name this tree has would probably overwhelm the article. I am removing the name - kanuga in telugu - from the article as of now. If someone else can come up with a compelling reason to keep it, feel free to reinsert it, but please state your reason here.

 * Well, the edit you reverted was clearly putting the name in the wrong place, so no objections to that. My general philosophy is that we should provide the names used when writing in English, and leave the others to dictionaries and interwiki links. Not sure how far I'd push this (especially for plants which are not commonly discussed in English). Kingdon (talk) 20:56, 17 May 2010 (UTC)

In the English version, it is given that all parts of the tree are toxic. But in Tamil version, it is given that the juice of the leaves cures stomach problems. " புங்கை இலைக்கு அல்சர் எனப்படும் வயிற்றுப் புண்ணை போக்கும் சக்தி உள்ளது. புங்கன் மர இலையை இடித்து சாறு பிழிந்து 30 முதல் 60 மில்லி அளவு குடித்து வர வயிற்றுப்புண் மற்றும் அதனால் ஏற்படும் வயிற்று வலி குணமாகும்."

 * Toxicity is a complicated subject; there is a level below which even a very toxic substance will show no toxic effects. This reference states that both the oils and residues are toxic and then goes into great detail regarding the traditional uses including for stomach problems. The article does mention this fact, but it is not followed by a reference, so I will add it in. Killian441 (talk) 15:39, 17 May 2012 (UTC)

Correct name
According to The Plant List, Millettia pinnata appears to be a synonym of Pongamia pinnata. So should we use the latter name? MKwek (talk) 08:22, 1 February 2013 (UTC)
 * The Plant List uses information from International Legume Database & Information Service which hasn't been updated since 2006. The ILDIS has two relevant entries, one for Pongamia pinnata and one for Millettia pinnata, both entries refer to the same basionym (Fabaceae Cytisus pinnatus) but don't seem to refer to each other. Millettia pinnata has the newer entry dating to 1989, while Pongamia pinnata dates to 1899. Since Pongamia has the longer history it will have more references, but from what I've been reading consensus is in favor of replacing Pongamia with Millettia. In fact, the Smithsonian National Museum of Natural History has a record of the proposal that the genus Pongamia be rejected in favor of Millettia in the International Code of Botanical Nomenclature (ICBN). It was first proposed in 1981, and looks like it was ratified in 1988. In 2011 the United States Department of Agriculture updated its database and made Pongamia pinnata a synonym of Milletia pinnata. Given that the Plant List is mostly an algorithmically generated database based on multiple sources it is perhaps not surprising that entries such as this will not reflect the new consensus. I believe the name Millettia pinnata is the more correct name at this point and should be kept. -Killian441 (talk) 18:46, 4 February 2013 (UTC)

At present, in Plant list, the accepted name is "Pongamia pinnata", which is based on the data from International Legume Database & Information Service provided on 2010-07-14. Now, in this database "Millettia pinnata" is only a synonym of "Pongamia pinnata", and no more an accepted name. Therefore the name of the page may be changed to Pongamia pinnata? Baluperoth (talk) 04:54, 25 July 2018 (UTC)
 * Hi, as mentioned above it was ratified that "Millettia" would replace "Pongamia" in 1988. Many other sources have not been updated yet. The International Legume Database & Information Service website is upgrading and currently under construction. Perhaps after it comes back online with updated data we can continue this discussion. -Killian441 (talk) 02:26, 2 August 2018 (UTC)

Proposed Edits
1. In paragraph 3 of the description section, add "in natural form" so that the last sentence reads "The seeds are about 1.5–2.5 centimetres (0.59–0.98 in) long with a brittle, oily coat and are unpalatable in natural form to herbivores.[5][6]"
 * Reason for the change: they are unpalatable only in natural form
 * References supporting change: https://www.foodnavigator-asia.com/Article/2020/08/04/Going-carbon-negative-TerViva-establishes-world-first-organic-pongamia-bean-supply-chain-in-India


 * Hello, the provided source says nothing to support this request. However, the page citation does support this request. Done. Heartmusic678 (talk) 16:36, 22 July 2021 (UTC)
 * ✅(ref name=daff_AU/) Heartmusic678 (talk) 17:11, 22 July 2021 (UTC)

2. In paragraph 2 of the uses section, add "The basic nutritional components of Pongamia pinnata seeds may change depending on the season and maturity of the tree but in general, it contains oil (27-39%), protein (17-37%), starch (6-7%), crude fiber (5-7%), moisture (15-20%) and ash content (2-3%)" to the beginning of paragraph 2.
 * ✅ Done. This fact was taken verbatim from, so I revised it. Heartmusic678 (talk) 17:11, 22 July 2021 (UTC)

3. While the oil and residue of the plant are toxic and will induce nausea and vomiting if ingested in natural form, the fruits and sprouts, along with the seeds, are used in many traditional remedies.[8] In this sentence, add the phrase "in natural form."
 * References supporting change: A report commissioned by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GmbH) and published by the New Delhi-based The Energy and Resources Institute (TERI). Page 7 https://www.terviva.com/wp-content/uploads/2020/10/GIZ-Pongamia-Report-2020.pdf
 * ✅ Done with minor revisions. Heartmusic678 (talk) 17:24, 22 July 2021 (UTC)

4. In the last paragraph of the uses section, delete sentence: If not managed carefully it can quickly become a weed leading some, including Miami-Dade County, to label the tree as an invasive species.
 * ✅ Removed Miami-Dade reference. Found evidence to keep first part of sentence, . Heartmusic678 (talk) 17:46, 22 July 2021 (UTC)

5. In the last paragraph of the uses section, add sentence: Long used as shade tree, M. pinnata is heavily self-seeding and can spread lateral roots up to 9 m (30 ft) over its lifetime. '''M. pinnata can reproduce itself from seed and after being introduced to some new habitats, it has become naturalized. In some areas, such as Miami-Dade County, M. pinnata is considered a controlled plant species. In other environments (e.g. Hawaii), observations of planted M. pinnata indicate that it is not displaying invasive tendencies. However''' this dense network of lateral roots makes this tree ideal for controlling soil erosion and binding sand dunes.[7]
 * Reference supporting change: https://www.miamidade.gov/environment/library/guidelines/controlled-species.pdf


 * ✅ Done, but provided reference doesn't support the request. Found one to support what was previously written in Uses paragraph 3 and another to support the general uncertainty of the nativity of M. pinnata in the regions it can be found. Heartmusic678 (talk) 13:41, 23 July 2021 (UTC)

6. In the research efforts section, add the following: A report commissioned and financed by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH found that M. pinnata seed meal, which is a by-product of oil recovery in plants, contains a higher percentage of protein, can be free from alkaloids and could be a source of supplementary protein for human diet.

I was able to find other references to the idea of using this plant's oil for use in generators to produce electricity, although it may simply be that they've sourced this information from this Wikipedia page:
