phytosociological analysis of Butia yatay (Arecaceae) palm groves and gallery forests in Entre Rios, Argentina [2017]
Estela E.; Rodriguez; Pablo G.; Aceñolaza; et al.
Multivariate floristic analyses of Butia yatay palm groves and gallery forest associated with the Uruguay River basin of Entre Rios Province (Argentina) were performed, including vegetation stands of Rio Grande do Sul State (Brazil). Several new phytosociological associations were identified. These include Eugenio myrcianthisâButietum yatay association, which represents palm groves on sandy soils evolved from ancient river deposits, and Bignonio callistegioidisâTerminalietum australis association, which represents some gallery forests on regular floodplains of the Uruguay River. Both are placed in the new Pampean alliance Guettardo uruguensisâBution yatay, which is part of the Dyckio brevifoliaeâTerminalietalia australis order and Sebastianio schottiaeâTerminalietea australis class, which has been described for Brazil.
