| Sumario: | This paper describes the plant communities found in the Paraná River valley. Several islands and parts of the floodplain of the Paraná River within the Province of Santa Fe (Argentina) were explored. The vegetation in this area is so complex that it is not possible to describe all communities in detail, but those that can be defined are referred to as noda. For descriptive purposes, they were divided into three main physiognomic groups.
Among the arboreal communities, the most evolved noda are the Forestum nigrum, Forestum insularis, and Forestum candicans (the latter lying outside the study area). Variants of these and other related noda include the Cathormietum, Sapietum, and Erythrinetum. The less evolved noda are the willow forest (Salicetum), with two variants, and the Tessarietum. Finally, there is a more xerophytic nodum, the mimosa forest or parkland of Acacia caven.
Among the shrubby communities, the best-defined noda are the Bambusetum and the Baccharisetum salicifoliae. Several other shrubby and bushy communities are either very heterogeneous or poorly defined.
The herbaceous communities include the Eichhornietum, Pistietum, Panicetum elephanthipes, and other floating types; the Polygonetum, Scirpetum, and Cyperetum; the Panicetum prionitis, Eragrosto-Fimbristyletum, and Distichletum. There are also a large number of mixed herbaceous communities and heterogeneous ones that cannot be segregated into definite noda.
The distribution of communities around water bodies is discussed, but no attempt is made to describe vegetation dynamics. |
