VASCULAR FLORA OF A SEASONAL SEMIDECIDUAL FOREST REMNANT IN MARINGÁ, BRAZIL

Abstract

The floristic composition of a remnant forest is characterized and will contribute towards knowledge on flora of the state of Paraná, Brazil. Botanic material was collected between May 2009 and October 2011 and in June 2014 by randomized rambling. Arboreal, shrub, herbaceous, liana and epiphytes specimens were collected, pressed following the usual methods and deposited at HUEM. Specific bibliography identified the flora collected and compared to the material deposited at HUEM and HCF, following APG III system for angiosperms. Further, 279 taxa were collected and identified, comprising 66 families, 213 genera and 244 species. The families with the largest number of species were Fabaceae (31), Asteraceae (24), Solanaceae (15), Sapindaceae (12), Euphorbiaceae and Malvaceae (11), Myrtaceae (10), Bignoniaceae (9), Rutaceae (8), Apocynaceae, Malpighiaceae, Meliaceae, Piperaceae and Rubiaceae (7). The above mentioned families comprised 59.5% of the species. Arboreal plants were predominant, with 107 specimens (38.4%); 95.5% (236 spp.) of the species were native plants and only 4.5% (11 spp.) were naturalized. Nine species are on the endangered list. Current analysis revealed high floristic diversity, similar to that by other authors who researched Semidecidual Seasonal Forests.
