However, the morphological similarities with\n                    <jats:italic>C. brevipes<\/jats:italic>\n                    have long challenged the taxonomic status of\n                    <jats:italic>C. oligantha<\/jats:italic>\n                    . Following the rediscovery of the species at its type locality in 2024, we conducted an integrative taxonomic reassessment of\n                    <jats:italic>C. oligantha<\/jats:italic>\n                    and\n                    <jats:italic>C. brevipes<\/jats:italic>\n                    based on the newly collected materials using combined analyses of molecular phylogenetics and morphological comparisons. Both molecular and morphological evidence congruently support the conspecificity of\n                    <jats:italic>C. oligantha<\/jats:italic>\n                    and\n                    <jats:italic>C. brevipes<\/jats:italic>\n                    . We therefore propose synonymizing\n                    <jats:italic>C. oligantha<\/jats:italic>\n                    under\n                    <jats:italic>C. brevipes<\/jats:italic>\n                    and recommend its exclusion from extinction lists. This study underscores the importance of robust taxonomic frameworks in preventing conservation misprioritization, and highlights the value of integrative, multidisciplinary approaches for establishing accurate biodiversity baselines prior to biological conservation action.\n                  <\/jats:p>","DOI":"10.3897\/phytokeys.278.203604","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T07:36:18Z","timestamp":1786952178000},"page":"157-176","source":"Crossref","is-referenced-by-count":0,"title":["Rediscovery and reexamination of a declared 'extinct' plant in South China: The species delimitation and conservation implications of Callicarpa oligantha (Lamiaceae)"],"prefix":"10.3897","volume":"278","author":[{"given":"Huimin","family":"Cai","sequence":"first","affiliation":[{"name":"National Demonstration Center for Experimental Plant Science Education, College of Agriculture, Guangxi University, Nanning, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiyi","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Plant Diversity and Specialty Crops, Guangdong Provincial Key Laboratory of Applied Botany, South China Botanical Garden, Chinese Academy of Sciences, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yicheng","family":"Xu","sequence":"additional","affiliation":[{"name":"Luofu Mountain State-owned Forest Farm, Huizhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tieyao","family":"Tu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Plant Diversity and Specialty Crops, Guangdong Provincial Key Laboratory of Applied Botany, South China Botanical Garden, Chinese Academy of Sciences, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhonghui","family":"Ma","sequence":"additional","affiliation":[{"name":"National Demonstration Center for Experimental Plant Science Education, College of Agriculture, Guangxi University, Nanning, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2258","published-online":{"date-parts":[[2026,8,17]]},"reference":[{"key":"203604_B1","doi-asserted-by":"publisher","DOI":"10.31234\/osf.io\/7awm6"},{"key":"203604_B2","doi-asserted-by":"publisher","DOI":"10.2307\/25065534"},{"key":"203604_B3","doi-asserted-by":"publisher","DOI":"10.1006\/mpev.1998.0545"},{"key":"203604_B4","doi-asserted-by":"publisher","DOI":"10.3732\/ajb.89.7.1093"},{"key":"203604_B5","doi-asserted-by":"publisher","DOI":"10.5962\/bhl.title.23084"},{"key":"203604_B6","doi-asserted-by":"publisher","DOI":"10.1007\/s12225-013-9456-y"},{"key":"203604_B7","doi-asserted-by":"publisher","DOI":"10.3389\/fpls.2023.1133157"},{"key":"203604_B8","unstructured":"Chang HT (1951) A review of the Chinese species of Callicarpa.
