“…Studies of internal and external Psychotria morphology have shown great anatomical and morphological variation (Davis, Bridson, Jarvis, & Govaerts, 2001;Quinteiro, Teixeira, Moraes, & Silva, 2007;Moraes, Rabelo, Alexandrino, Silva Neto, & Cunha, 2011;Nery, Ribas, & Koehler, 2014;Pinheiro, Kolb, & Rossatto, 2018), which makes it difficult to establish determinative morphological structures for the group taxonomy. Domatia was considered determinant for the taxonomy of P. viridis in Atlantic Forest (Quinteiro et al, 2007).…”
