| English abstract | Background: Attaining a reasonable floristic knowledge for any given region is a progressive task, of gradual, periodic accumulation of data with no deadline, beyond programmatic or budgetary limitations. The knowledge gained synthesized in floristic checklist, regional taxonomic treatments, and floras. The taxonomic studies of particular groups, traditionally known as treatments, frequently reveal changes in the knowledge of biodiversity that must be incorporated periodically into floristic checklist and floras. Also, phylogenetic systematics, especially that based on molecules, has yielded dramatic changes in the way we understand relationships and classify organismic diversity, and also needs to be taken into account. No less important are the regional taxonomic novelties and new species for Science described from material originally collected and / or exclusively in the area of interest, in this case, the Mexican portion of the Yucatan Peninsula (MYP). Finally, practicing systematists often change their opinion in relation to circumscriptions of particular organisms as a consecuence of the evaluation of new evidence. Also, we make mistakes that must be corrected. This work summarizes the daily task of increasing and updating the floristic knowledge of the MYP. Question: How many species of vascular plants grow wild in the MYP? How many of these are endemic to this area? What important floristic and taxonomic changes have occurred since the publication of the last checklist? What human resources and infrastructure are currently available to study this flora? What are the gaps in our floristic and taxonomic knowledge? Studied species: Gimnosperms, ferns and related groups, Angiosperms. Study site and and years of study: The MYP is made up of the states of Campeche, Quintana Roo, and Yucatan. As a biogeographic unit, its extends to the northern portion of Belize (Departments of Belize, Corozal, and Orange Walk) and the Peten in Guatemala. This is a co |
