Ramírez-Morillo, Jorge Cortés-Flores, José Arturo de-Nova, Rodrigo Duno de Stefano, Germán Carnevali Fernández-Concha","doi":"10.3100/hpib.v28iss1.2023.n13","DOIUrl":"https://doi.org/10.3100/hpib.v28iss1.2023.n13","url":null,"abstract":"The increased availability of phylogenetic, morphological, and geographic information from different biological groups has allowed for the testing of several scenarios on the origin and assembly of the biota around the world. The biogeographical approaches used to understand the origin of the Yucatan Peninsula Biotic Province (YPBP) flora were previously based on floristic comparisons and do not consider the phylogenetic relationships among taxa, complicating the understanding of their biogeographical history. In order to improve the understanding of biogeographical and evolutionary processes implied in the occurrence of the endemic flora of the YPBP, we constructed a geobiotic scenario, which integrates lineage divergence events obtained from previous phylogenetic and biogeographical studies, along with geological/tectonic and climatic events occurring in the area. To strengthen the biogeographical hypotheses, we constructed a phylogenetic tree as a framework for an approximation of the periods of history with the greatest influence on the evolution of the flora. Additionally, we searched for morphological traits of relevance for dispersal, establishment, and adaptation to the current environmental conditions of the YPBP. The evidence gathered in the present work strongly suggests that the origin of the endemic flora of the YPBP has been driven by various factors and processes that occurred at different times in the history of the Earth (mainly in the Pliocene and early Pleistocene). These include hybridization, isolation after long-distance dispersal from the Antilles, as well as the influence of environmental changes during the Pleistocene. Those climatic fluctuations reduced the geographic range of some ancestral lineages, leading to geographic isolation of populations in the northern part of the YPBP, where the climate has been more stable over time.","PeriodicalId":39248,"journal":{"name":"Harvard Papers in Botany","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136365819","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}

Magnolia pajarito, a new species from the Andean slopes of the Eastern Cordillera of Colombia, is described and illustrated, and its morphological relationships with other similar Magnolia species are discussed. This new species is a tree between 9 and 30 m tall from montane forest remnants and pasture lands with dispersal trees (1500–1700 m), and it does not appear to be closely allied to any particular Magnolia species. This new species shares several features with four other species (M. arcabucoana, M. caricifragans, M. santanderiana, and M. virolinensis) in section Talauma. Morphologically it has some similarity to M. arcabucoana, but it differs in the length of the adaxial scar of the petiole, the size and shape of the leaf blade, the sepal and inner petal, and in the number of secondary veins, vaginal hypsophyl, and stamens. Additionally, habitat information, a distribution map, and data on Magnolia conservation status are included. An identification key of species of Magnolia found in Colombia is also provided. This new species elevates to 40 the number of Magnolia taxa for the flora of Colombia, of which 31 are endemic. Colombia has the highest diversity of the genus in the neotropics. Resumen. Magnolia pajarito una nueva especie de las vertientes de la Cordillera Oriental de los Andes de Colombia, es descrita, ilustrada y se discuten sus relaciones morfológicas con otras especies similares. Esta nueva especie es un árbol entre 9 y 30 m de altura, que se encuentra en remanentes de bosques montanos y con árboles dispersos (1500–1700 m) y aparentemente no esta cercanamente relacionada con ninguna especie en particular de Magnolia. M. pajarito comparte algunos caracteres con cuatro especies (M. arcabucoana, M. caricifragans, M. santanderiana y M. virolinensis) de la sección Talauma.
