Distribution: — Anthurium gladiifolium is endemic to Brazil, occurring in Bahia, Espírito Santo, Minas Gerais, and Rio de Janeiro ( Flora do Brasil 2020). It was found at the Pedra do Pato trail (central PESB) and this is the first record of the species for this Park.

Ecology and phenology: —Flowering period from November to January ( Camelo et al. 2020), probably flowering throughout the year. In the PESB, it was found with flowers in February. Only one individual per phorophyte was observed.

Taxonomic notes: —Differs from other Anthurium species found in the PESB by its concolorous leaf blade with obscure primary lateral veins, its vinaceous spadix and by its reddish berries with yellow base.
