Abstract
Pavonia stands out as one of the most diverse genera within the Malvaceae, boasting 270 species with a widespread distribution throughout the Americas. The defining characteristics of the genus include the presence of an epicalyx, five carpels, 10 stigmas, and the absence of nectaries in the leaf and foliaceous bracts. This research focuses on presenting the Pavonia species in the state of Pernambuco, located in Northeastern Brazil, utilizing herbarium consultations. Among the 13 Pavonia species documented in Pernambuco, the majority are distributed across the Caatinga (7 species) and the Mata (5 species) phytogeographic zones. Notably, P. cancellata is found in all zones. This study unveils two new records for Pernambuco—P. hexaphylla and P. repens. Additionally, the distribution of P. ducke-limae, originally endemic to the Atlantic Forest, is expanded. Within the Caatinga, three species—P. glazioviana, P. repens, and P. varians are identified as endemic. Furthermore, lectotypification is performed for the names P. blanchetiana, P. glazioviana, and P. varians.
