Abstract
The Department of Ñeembucú is one of the least well-documented areas of eastern Paraguay, and the flora is composed of a mixture of forest and Chaco elements. Regions like Ñeembucú are often considered of lower diversity and interest that more forested regions; this results from both actual species richness figures and from under-collecting due to perception as uninteresting. We present here a checklist of the vascular plants of Ñeembucú, which includes 676 taxa (including infraspecific taxa and collections identified only to genus) in 100 families and 374 genera. Four hundred and thirty nine (439) of these are new records for Ñeembucú and of these, 4 are new published records for Paraguay. Synonyms, distribution details within Paraguay and a voucher specimen or literature record are provided for each taxon, and a brief analysis of the diversity and importance of the flora is presented.
Highlights
Paraguay is a land-locked country between 19° and 28° south latitude and 54° and 63° west longitude at the heart of the South American continent, and lies entirely within the Río de la Plata drainage system, second only in size to the Amazon basin
A total of 439 taxa not previously recorded for the department are included here; 254 of these are new additions for the department resulting from our studies, 171 have been cited in other sources but not in Zuloaga et al (2008), and 4 taxa have not been cited previously as occurring in Paraguay
Nine families have more than 20 taxa in Ñeembucú (Table 1)
