Araceae no Núcleo Curucutu, Parque Estadual Serra do Mar, Estado de São Paulo, Brasil

This paper presents a taxonomic survey of Araceae in the Núcleo Curucutu. For distinction of the species, we elaborated an identification key, morphological descriptions, illustrations, alongside geographical distribution, and phenological data. The family is represented in the area by twelve species: Anthurium acutum N.E.Br., A. comtum Schott, A. loefgrenii Engl., A. longicuspidatum Engl., A. marense K.Krause, A. pentaphyllum (Aubl.) G.Don, A. sellowianum Kunth, Monstera adansonii Schott, Philodendron appendiculatum Nadruz & Mayo, P. glaziovii Hook.f., P. propinquum Schott., and P. roseopetiolatum Nadruz & Mayo. Ten of these species are endemic to Brazil, with nine classified under some category of extinction risk.
