During botanical surveys in northeastern Thailand, an unusual population of Typhonium was discovered in mixed deciduous forest and dry evergreen forest at 300\u2013400 m elevation. Detailed morphological study of living plants and herbarium specimens, together with comparisons with relevant protologues, regional floras, and recently described species, confirmed that this population represents a species new to science. It is here described as Typhonium mukdahanense Chatan &amp; Promprom, sp. nov. The new species is morphologically most similar to T. fornicatum, but differs by its taller habit, larger hastate to trisect leaf blades, more numerous primary lateral veins, larger and nearly symmetrical spathe tube, triangular reflexed spathe limb, dark red stigma with a cream-colored depressed center, sterile interstice bearing 10\u201314 staminodes arranged in two whorls, slightly curved and not spreading\u2013declinate appendix, and pyriform mottled berries. It also differs from T. acetosella by its broader leaf blades, reflexed triangular spathe limb, dark red stigma, and pyriform fruits. The new species is currently known only from the type locality and is therefore provisionally assessed as Critically Endangered (CR) according to the IUCN Red List Categories and Criteria. A detailed description, diagnosis, information on distribution, habitat, phenology, conservation status, and an identification key to morphologically similar species are provided.<\/jats:p>","DOI":"10.3390\/life16081376","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T12:57:53Z","timestamp":1787230673000},"page":"1376","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Discovery of Typhonium mukdahanense (Araceae), a New Species from Northeastern Thailand"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8821-2267","authenticated-orcid":false,"given":"Wilawan","family":"Promprom","sequence":"first","affiliation":[{"name":"Department of Biology, Faculty of Science, Mahasarakham University, Maha Sarakham 44150, Thailand"},{"name":"Plant and Innovation Research Unit, Mahasarakham University, Maha Sarakham 44150, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7247-2873","authenticated-orcid":false,"given":"Phukphon","family":"Munglue","sequence":"additional","affiliation":[{"name":"Plant and Innovation Research Unit, Mahasarakham University, Maha Sarakham 44150, Thailand"},{"name":"Program of Biology, Faculty of Science, Ubon Ratchathani Rajabhat University, Ubon Ratchathani 34000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-7656-8436","authenticated-orcid":false,"given":"Chuthep","family":"Phannasri","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Science, Mahasarakham University, Maha Sarakham 44150, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3941-7626","authenticated-orcid":false,"given":"Wannachai","family":"Chatan","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Science, Mahasarakham University, Maha Sarakham 44150, Thailand"},{"name":"Plant and Innovation Research Unit, Mahasarakham University, Maha Sarakham 44150, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,20]]},"reference":[{"key":"ref_1","unstructured":"POWO (2026, June 08).
