We investigated colour change and pollinator visitation in\n                    <jats:italic>Firmiana daweishanensis<\/jats:italic>\n                    , a Plant Species with Extremely Small Populations endemic to southeastern Yunnan, China. Using a 25\u2010m scaffold, we observed 16 flowering branches on one adult tree for 128 branch\u2010hours. We combined these observations with measurements of linalool emission, nectar accumulation, reproductive function, calyx reflectance and bee visual modelling. Six hymenopteran taxa visited the tree, with\n                    <jats:italic>Megachile<\/jats:italic>\n                    bees dominating visitation. Mixed models showed that yellow flowers received more visits and greater cumulative visitation time per flower\u2010hour than red flowers within both sexes. Neither the omnibus sex tests nor the colour \u00d7 sex interactions were significant. Branch\u2010level floral abundance and colour composition were not significantly associated with visitation. This contrast was consistent with, but did not demonstrate, selection at a fine spatial scale; limited statistical power remained an alternative explanation. Yellow flowers showed higher linalool emission and stronger modelled green\u2010receptor contrast against a green background. Nectar availability and reproductive function were generally greater during earlier floral stages. Neither pollinator\u2010excluded nor artificially geitonogamously self\u2010pollinated flowers produced fruit, whereas naturally exposed flowers showed 6.19% fruit set. These observations support a contribution of floral visitors to fruit set, but the absence of a hand\u2010cross\u2010pollinated control prevented a conclusive assessment of self\u2010incompatibility. Because colour, age, scent, reward and reproductive state covaried, their individual contributions to visitation could not be distinguished. Floral colour change may therefore form part of a multimodal indicator of floral state, while any display function of retained red flowers remains hypothetical. This within\u2010tree case study documents canopy visitation patterns whose generality requires replication across individuals and populations.\n                  <\/jats:p>","DOI":"10.1002\/ece3.74490","type":"journal-article","created":{"date-parts":[[2026,10,13]],"date-time":"2026-10-13T03:46:48Z","timestamp":1791863208000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Pollinator Visitation Within a Single Crown of the Rare Rainforest Tree\n                    <i>Firmiana daweishanensis<\/i>\n                    Is Associated With Floral Colour Change"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-7745-289X","authenticated-orcid":false,"given":"Bo\u2010Qiang","family":"Wang","sequence":"first","affiliation":[{"name":"Yunnan Key Laboratory for Integrative Conservation of Plant Species With Extremely Small Populations, Kunming Institute of Botany Chinese Academy of Sciences  Kunming China"},{"name":"University of Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Si\u2010Yue","family":"Xiao","sequence":"additional","affiliation":[{"name":"Yunnan Key Laboratory for Integrative Conservation of Plant Species With Extremely Small Populations, Kunming Institute of Botany Chinese Academy of Sciences  Kunming China"},{"name":"University of Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng\u2010Jie","family":"Li","sequence":"additional","affiliation":[{"name":"Yunnan Key Laboratory for Integrative Conservation of Plant Species With Extremely Small Populations, Kunming Institute of Botany Chinese Academy of Sciences  Kunming China"},{"name":"University of Chinese Academy of Sciences  Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan\u2010Mei","family":"Ping","sequence":"additional","affiliation":[{"name":"Forestry and Grassland Bureau of Hekou County  Hekou Yunnan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin\u2010Guo","family":"Zhang","sequence":"additional","affiliation":[{"name":"Maguan Gulinqing Provincial Nature Reserve Management and Protection Bureau  Maguan Yunnan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5246-9226","authenticated-orcid":false,"given":"Wei\u2010Bang","family":"Sun","sequence":"additional","affiliation":[{"name":"Yunnan Key Laboratory for Integrative Conservation of Plant Species With Extremely Small Populations, Kunming Institute of Botany Chinese Academy of Sciences  Kunming China"},{"name":"State Key Laboratory of Plant Diversity and Specialty Crops, Kunming Institute of Botany Chinese Academy of Sciences  Kunming China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Yang","sequence":"additional","affiliation":[{"name":"Yunnan Key Laboratory for Integrative Conservation of Plant Species With Extremely Small Populations, Kunming Institute of Botany Chinese Academy of Sciences  Kunming China"},{"name":"State Key Laboratory of Plant Diversity and Specialty Crops, Kunming Institute of Botany Chinese Academy of Sciences  Kunming China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,12]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1890\/03\u20108024"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0169\u20105347(96)81046\u20109"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.es.21.110190.002151"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/1365\u20102435.12537"},{"key":"e_1_2_10_6_1","volume-title":"Pollination Ecology: A Practical Approach","author":"Dafni A.","year":"1992"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpls.2020.601700"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.3732\/ajb.90.12.1751"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ecolsys.29.1.83"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/ele.12386"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1663\/0006\u20108101(2006)72[1:DADOFS]2.0.CO;2"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/beheco\/12.4.447"},{"key":"e_1_2_10_13_1","volume-title":"Forest Canopies","author":"Lowman M.
