The Gunma Ecological Park - PEG (Santa Bárbara do Pará, Pará state, Brazil) is one of the few preserved forest remnants in the metropolitan region of Belém. The PEG has a rich phanerogamic flora with rare species, but nothing is known about its seedless vascular-plant flora. Our aim is to present a floristic survey of ferns and lycophytes from Gunma Ecological Park. The 56 recorded species belong to 28 genera and 15 families. This is the first record for Lellingeria suspensa (L.) A.R. Sm. & R.C. Moran in Pará state and also for Polyphlebium diaphanum (Kunth) Ebihara & Dubuisson in the Brazilian Amazon. The richest families were Hymenophyllaceae (15 spp.), Dryopteridaceae (8 spp.), Polypodiaceae (7 spp.) and Pteridaceae (6 spp.). The genera with highest number of species were Trichomanes (7 spp.) and Elaphoglossum (6 spp.). The majority of the species were herbaceous (52 spp.), with epiphytic (30 spp.) and terrestrial (23 spp.) habitat, occurred exclusively in the understory (35 spp.) and presented American distribution (34 spp.). This result demonstrates the importance of Gunma Ecological Park for local/regional seedless vascular-plant flora preservation. |
