The phytogeographic and floristic connections of the “Montes de Maria” (MM: north of Colombia) were analyzed through Geographic Information Systems, at worldwide, Neotropical and in Colombia scales in order to determine its geographical origin and floristic affinities. We estimated that genera are mostly of the Neotropical (74%) and Nearctic (26%) origin. At the Neotropical level, MM is located at the Pacific dominion and shares species with the Mesoamerican dominion. In addition, shares species with the Chaqueña, Antilles subregions, and the South American and Mexican transition zones. At the regional level, the MM is located between Guajira and Magdalena provinces, although is floristically more similar to Guajira province. MM shape a floristic unit together with other fragments of dry forest in the Colombian Caribbean, which is highly related to dry forests of the inter-Andean valleys. In addition, the floristic origin of MM is associated to dry flora of Mesoamerica, nonetheless it was also influenced by the Amazonian and the Sabana province.

“Los Montes de María”中木本植物的植物地理学和植物区系亲缘关系，哥伦比亚加勒比地区的热带干燥森林片段

“Montes de Maria”（MM：哥伦比亚北部）的植物地理和植物区系联系通过地理信息系统在全球、新热带和哥伦比亚范围内进行分析，以确定其地理起源和植物区系亲缘关系。我们估计属主要来自新热带 (74%) 和近北 (26%) 起源。在新热带级别，MM 位于太平洋自治领，与中美洲自治领共享物种。此外，与 Chaqueña、安的列斯次区域以及南美和墨西哥过渡区共享物种。在区域层面，MM 位于瓜希拉省和马格达莱纳省之间，尽管在植物区系上与瓜希拉省更相似。MM与哥伦比亚加勒比地区的其他干燥森林片段一起形成一个植物区系，这与安第斯山谷间的干燥森林高度相关。此外，MM 的植物区系起源与中美洲的干燥植物区系有关，但它也受到亚马逊和萨巴纳省的影响。
