• Abstract:

  The phenological events of three species from the Marantaceae family were studied in the Mendanha hill Municipal Natural Park, namely: Maranta cristata Ker. Gawl., Maranta leuconeura (E. Morren.) and Goeppertia monophylla (Vell) Borchs & S. Suárez. Observations were carried out over 67 months (October 2014 to April 2020). The flowering and fruiting of the species are seasonal, annual and regular. Flowering of M. cristata and M. leuconeura occurs from August to March and fruiting from August to April. The flowering period of G. monophylla occurs from November to February, with fruiting between January and March. The flowering peak of all species occurs in the months of November to January and the fruiting peak in the months of January and February, during the rainy season. The species have capsule-type fruits, with ca. 10 mm long, with one seed. For species of the Marantaceae family, in the Mendanha hill, the correlation is significantly positive between the phenophases (flowering and fruiting) and the abiotic factors (average temperature and precipitation).
