Neesia Aquatica: "Cemenang"
[edit]I want to add Cemenang as a redirect to a page in wikipedia, but I am not a biologist. This is my research:
Neesia Aquatica is not at Neesia
Neesia aquatica occurs in texts by people studying Suaq orangutans Sumatran orangutan:
https://pmc.ncbi.nlm.nih.gov/articles/PMC5041519/ Tool use can be divided into two broad classes: insect tool use, where sticks are used to get access to insects or their products in tree holes, nests and other substrates, and fruit tool use, where sticks are inserted into the valves of the fruits of Neesia aquatica to facilitate seed extraction

https://onlinelibrary.wiley.com/doi/abs/10.1002/ajpa.1045 In this study, we compare the feeding techniques and tool-using skills used by orangutans to extract the nutritious seeds from Neesia fruits between Suaq Balimbing on Sumatra and Gunung Palung on Borneo, and map the distribution of Neesia tool use in Sumatran swamps.

https://suaq.org/orangutans/the-suaq-culture/ At the edge of the Suaq peat swamp forest, there are Neesia trees (Neesia aquatica) with fruits filled with nutritious seeds, a highly preferred food of the Suaq orangutans. These seeds are hidden inside a football-shaped, extremely hard-shelled husk and protected by a mass of razor-sharp needles inside the husk.
http://www.malvaceae.info/Genera/Neesia/Neesia.php Neesia aquatica is widely mentioned in the context of regional variations in Orang-Utang culture. (The fruits of Neesia are a significant component of the diet of Orang-Utangs, who use tools - sticks - to separate the irritant hairs from the edible portions of the fruit.) I am unaware of the status of this name.

contains:
Local name - Cemengang
Scientific name - Neesia aquatica
Family - Bombaceae (Bombacaceae), however, Genera of tribe Durioneae excluded from Bombacaceae after Heywood et al. 2007 and that should be included in Durionaceae, thus:
Family - Durionaceae

Orangutans in Suaq Balimbing were recorded to develop a tool kit for use in foraging which consisted of both insect-extraction sticks for use in the hollows of trees and seed-extraction sticks for harvesting seeds from hard-husked fruit. - Orangutan#Tool use and culture

Plant databases like Plants of the World Online and International Plant Names Index don't recognize the name Neesia aquatica.
Include one or more reliable references - Plants of the World Online, World Flora Online, IPNI, Tropicos, etc. - which confirm the plant's accepted binomial.
Neesia synandra seeds are eaten by some orangutans
[edit]It would be a worthy addition to this article if something about the fruits and seeds of these plants is mentioned. ~2025-42565-19 (talk) 18:22, 23 December 2025 (UTC)
