The article "Exploring biodiversity of Uruguayan vascular plants through DNA barcoding" published in Frontiers in Genetics on October 15, 2024, discusses the use of DNA barcoding to study the biodiversity of Uruguayan vascular plants. The study aims to address the decline in biodiversity in Uruguay by establishing a DNA barcode national network. By analyzing 171 sequences from four loci for 50 vascular plant species, the researchers identified suitable markers for plant DNA barcoding and contributed to the Uruguayan Barcode of Life Initiative. The study highlights the importance of creating a comprehensive public database for species identification and biodiversity research. [Extracted from the article]

Galianthe valerianoides (Spermacoceae-Rubiaceae) is recorded for the first for the Uruguayan flora (Dpto. Rivera), and as a consequence, its distribution area extends to its southernmost limit. A detailed morphological description, a distribution map in Uruguay, and photographs of the habitat are given for G. valerianoides. Also, a key to the Galianthe species present in Uruguay is provided. [ABSTRACT FROM AUTHOR]

Telmatoblechnum, with the species Telmatoblechnum serrulatum (Blechnaceae), is recorded for the first time for the Uruguayan flora. The species, so far known from southern Brazil and Northeastern Argentina as its southernmost distribution limit, was collected for the first time in crevices between rocks of basalt and sandstone in a small hill in Uruguay (Rivera). Its morphological characteristics and the novel habitat for the species are included; photographs, a map with the location of the new record, as well as a key to the genera of Blechnaceae in Uruguay are provided.
