We present the comparative vegetative morphology, a key to the species, distribution, ecology, preliminary conservation assessments, utilization, and specimens examined. <jats:italic>Korthalsia flagellaris<\/jats:italic> is lectotypified here in a second-step. Three Thai <jats:italic>Korthalsia<\/jats:italic> species are confined to the peninsular region: <jats:italic>K. flagellaris<\/jats:italic>, <jats:italic>K. scortechinii<\/jats:italic> and <jats:italic>K. rigida<\/jats:italic>. The first, <jats:italic>K. flagellaris<\/jats:italic>, is known only from Narathiwat province and is restricted to peat swamp forests. The second, <jats:italic>K. scortechinii<\/jats:italic>, is myrmecophilous and found only in Narathiwat in lowland tropical evergreen rainforests. The third, <jats:italic>K. rigida<\/jats:italic> has a wider distribution and is known from Ranong, Trang and Narathiwat provinces in lowland tropical evergreen rainforests. Lastly, <jats:italic>Korthalsia laciniosa<\/jats:italic> is the most widespread species of the genus in both the south-eastern and peninsular regions of Thailand in lowland tropical evergreen rainforests. All Thai <jats:italic>Korthalsia<\/jats:italic> species are currently assessed as Least Concern (LC) under the IUCN conservation status. In Thailand, <jats:italic>Korthalsia<\/jats:italic> is used for traditional tools, furniture components, and fishery equipment. Its stems are valued in local crafts, while the young shoots are occasionally consumed as food.<\/jats:p>","DOI":"10.7717\/peerj.19935","type":"journal-article","created":{"date-parts":[[2025,8,19]],"date-time":"2025-08-19T08:51:01Z","timestamp":1755593461000},"page":"e19935","source":"Crossref","is-referenced-by-count":1,"title":["An account of <i>Korthalsia<\/i> (Arecaceae) rattans and their uses in Thailand"],"prefix":"10.7717","volume":"13","author":[{"given":"Chatchai","family":"Ngernsaengsaruay","sequence":"first","affiliation":[{"name":"Department of Botany, Faculty of Science, Kasetsart University, Chatuchak, Bangkok, Thailand"},{"name":"Biodiversity Center Kasetsart University (BDCKU), Kasetsart University, Chatuchak, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nittaya","family":"Mianmit","sequence":"additional","affiliation":[{"name":"Department of Forest Management, Faculty of Forestry, Kasetsart University, Chatuchak, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nisa","family":"Leksungnoen","sequence":"additional","affiliation":[{"name":"Department of Forest Biology, Faculty of Forestry, Kasetsart University, Chatuchak, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phruet","family":"Racharak","sequence":"additional","affiliation":[{"name":"Department of Forest Biology, Faculty of Forestry, Kasetsart University, Chatuchak, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2459-8564","authenticated-orcid":true,"given":"Suwimon","family":"Uthairatsamee","sequence":"additional","affiliation":[{"name":"Department of Forest Biology, Faculty of Forestry, Kasetsart University, Chatuchak, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7325-6109","authenticated-orcid":true,"given":"Pichet","family":"Chanton","sequence":"additional","affiliation":[{"name":"Suan Luang Rama IX Foundation, Nong Bon Subdistrict, Prawet District, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tushar","family":"Andriyas","sequence":"additional","affiliation":[{"name":"Department of Food and Pharmaceutical Chemistry, Faculty of Pharmaceutical Sciences, Chulalongkorn University, Pathumwan, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wirongrong","family":"Duangjai","sequence":"additional","affiliation":[{"name":"Department of Silviculture, Faculty of Forestry, Kasetsart University, Chatuchak, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4443","published-online":{"date-parts":[[2025,8,19]]},"reference":[{"key":"10.7717\/peerj.19935\/ref-1","doi-asserted-by":"publisher","first-page":"117","DOI":"10.3897\/zookeys.150.2109","article-title":"Supporting red list threat assessments with GeoCAT: geospatial conservation assessment tool","volume":"150","author":"Bachman","year":"2011","journal-title":"ZooKeys"},{"issue":"1","key":"10.7717\/peerj.19935\/ref-2","doi-asserted-by":"publisher","first-page":"39","DOI":"10.3767\/000651909X476003","article-title":"Specialty rattans of the ASEAN","volume":"54","author":"Baja-Lapis","year":"2009","journal-title":"Blumea-Biodiversity Evolution and Biogeography of Plants"},{"key":"10.7717\/peerj.19935\/ref-3","first-page":"323","article-title":"Arecaceae","volume-title":"Flora of Thailand","volume":"11","author":"Barfod","year":"2013"},{"key":"10.7717\/peerj.19935\/ref-4","first-page":"7","article-title":"Piante ospitatrici","volume":"2","author":"Beccari","year":"1884","journal-title":"Malesia"},{"issue":"3","key":"10.7717\/peerj.19935\/ref-5","first-page":"1","article-title":"Asiatic palms-Lepidocarye\u00e6: the species of the genera","volume":"12","author":"Beccari","year":"1918","journal-title":"Annals of the Royal Botanic Garden, Calcutta"},{"key":"10.7717\/peerj.19935\/ref-6","first-page":"402","article-title":"Palmeae","volume-title":"Flora of British India","volume":"6","author":"Beccari","year":"1893"},{"key":"10.7717\/peerj.19935\/ref-7","volume-title":"Rumphia, sive commentationes botanicae imprimis de plantis Indiae Orientalis","volume":"2","author":"Blume","year":"1843"},{"issue":"4","key":"10.7717\/peerj.19935\/ref-8","doi-asserted-by":"publisher","first-page":"2010","DOI":"10.1016\/j.ygeno.2021.04.023","article-title":"Draft genome of Korthalsia laciniosa (Griff.)
