First field collections from Swabi revealed diagnostic characters including deeply lobed leaves, yellow ephemeral flowers, elongated floral tubes, and cylindrical capsules. Chloroplast <i>rbcL</i> sequences confirmed identity. Global records show a broad but discontinuous distribution across North America, Europe, and East Asia, with sparse occurrences in Africa, South America, Australia, and South Asia, including eight verified records from Pakistan. Climatic analyses showed a narrow temperature niche (mean 17.69°C ± 3.41 SD; range 3.08°C–26.20°C), with a strong latitudinal relationship (<i>R</i><sup>2</sup> = 0.133), while longitudinal influence was weak (<i>R</i><sup>2</sup> = 0.003). Hydroclimatic analyses revealed a broader precipitation niche (mean 735.84 mm ± 385.58 SD; range 149–2917 mm), with occurrences in semi-arid to sub-humid regions, avoiding extreme arid and hyper-humid environments. Precipitation variation was governed by longitude (adjusted <i>R</i><sup>2</sup> = 0.100). These findings suggest that although the species possesses high dispersal capacity, its realized distribution remains structured by temperature and precipitation constraints. This study expands Pakistan's floristic diversity, provides the confirmed record of <i>O. laciniata</i> from South Asia, and highlights the importance of combining taxonomy with DNA barcoding for documenting overlooked alien species.</p>\u0000 </div>","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"137 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study compared the population structure, regeneration, and health condition of <i>U. kirkiana</i> between these ecologically distinct reserves. Fifty circular sample plots were established, 20 in Perekezi and 30 in Kaning'ina. Mature individuals were measured for diameter at breast height (DBH), height, crown diameter, and health condition, while juveniles were counted to assess regeneration. Data were analyzed using independent-samples <i>t</i>-tests and gamma distribution fitting, following normality and variance homogeneity tests. Kaning'ina had significantly larger, older trees (mean DBH = 20.58 ± 9.38 cm) than Perekezi (11.42 ± 5.08 cm; <i>p</i> &lt; 0.001). Perekezi had more healthy trees and greater juvenile abundance, indicating active recruitment. Both sites displayed an inverted <i>J</i>-shaped distribution typical of regenerating populations, but Kaning'ina showed recruitment decline linked to urban proximity and disturbance. These findings reveal site-specific demographic trends and underscore the need for differentiated management, including community-based protection, to sustain <i>U. kirkiana</i> across northern Malawi's miombo landscapes.</p>\u0000 </div>","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"137 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
