Expedition to Patagonia, Tierra del Fuego and Antarctica0 abotanical collections Pteridophyta and Spermatophyta of the AMF   a455-5340 v323 aOur paper consists of an annotated list of the collections and some notes on the vegetation of the localities we have visited during our journey. Originally, we intended to add a chapter on the origin and palaeontonlogical history of the Patagonian flora, but the scarce representation of specimens from that region in the European herbaria, the consideration that there is no possibility of dealing with this subject without taking into account the flora of Chile, and, finally, the fact that too many plants not collected by us would hav been involved in this research, convinced us to give up this project. Nevertheless, we have regarded it advisable to utilize the data accumulated during our research-work and to add some phytogeographical considerations in the comments to species. Our considerations are fragmentary and do not allow us to achieve a synthetic view on this subject, but the few data we have assembled show very clearly how fascinating and interesting would be a study on the genesis and evolution of the flora of the southern regions of the American continent.10aJuncaginaceae, Tetroncium magellanicum10aPatagonia, Tierra del Fuego, Antarctica1 aPichi Sermolli, Rodolfo, E G1 aBizzarri, Maria Paola  uhttps://juncaginaceae.myspecies.info/node/275
