A new species of Hedeoma (Lamiaceae) is described based on samples collected in Misiones Province, Argentina. A botanical illustration, photos of the new taxon, information about its habitat, status of conservation, and importance for local people is also provided, including a key to the species of Hedeoma from the Southern Cone of America.

Azorella is a genus with 26 species of Azorelloideae (Apiaceae) that grow from Costa Rica to the subantartic islands, being distintive and dominant in different environments of the Andean Cordilleras from Venezuela to Patagonia. The species of Azorella that grow in Argentina have been revised taxonomically in a previous study. However, knowledge of the remaining species is fragmentary and uneven. The aim of this paper is to update and standardize the information of the 11 species of Azorella absent in Argentina and present in Bolivia, Chile, Colombia, Ecuador, Peru and/or Venezuela. We provide descriptions for those species and update distributional maps, and we solve nomenclatural and typification problems for 41 names, designating 2 type species, 16 lectotypes and 1 neotype. In addition, we provide 10 new illustrations, and an identification key for all the species of the genus.

The aim of the present study was to characterize karyologically species of Passiflora L. from Felix Perez Cardozo District, Guaira, Paraguay. The chromosome numbers in meiosis 2n = 9II for P. alata Curtis and P. caerulea L. are reported for the first time. Chromosome number for P. edulis Sims (2n = 9II) is also confirmed. Meiotic behaviour in all studied species was normal with regular chromosome segregation. The most frequent chromosome associations were bivalents at diakinesis and metaphase I. Few meiotic irregularities were observed, such as lagging chromosomes and asynchronous phases of meiosis II, however, pollen viability was high, between 78.83% and 98.6%. The obtained results confirms x = 9 as the basic chromosome number for subgenus Passiflora. The present study is a relevant contribution to the knowledge on the cytogenetics of species of Passiflora subg Passiflora from Paraguay.

En este trabajo se confirma que el area de distribucion de Lygodium venustum incluye el noreste de la Argentina, a partir de la reciente coleccion de ejemplares en el Parque Provincial Mocona, provincia de Misiones, y de la identificacion de material de herbario, que corroboran una antigua cita dudosa de esta especie. Este registro representa el limite austral de distribucion de la especie. Se describen e ilustran los caracteres diagnosticos y se brinda una clave de identificacion, asi como material de referencia de las especies de Lygodium del Cono Sur de America. Se lectotipifican Lygodium venustum, L. pohlianum y L. palmatilobum, se sinonimiza a L. palmatilobum bajo Lygodium venustum. Se considera a Lygodium hastatum, L. palmatilobatum y L. potentilloides como nombres invalidos

Lythrum salicaria , una de las especies de mas amplia distribucion geografica del genero, crece en ambientes riparios en varios paises y resulta altamente invasiva fuera de su area de distribucion natural. En este trabajo se informa por primera vez la presencia de una poblacion espontanea de L. salicaria en Argentina.
