A list of angiosperms from Serra do Urubu, a montane forest area in the state of Pernambuco, is here provided. Based on 14 botanical expeditions and material deposited in herbaria, 832 taxa belonging to 442 genera and 118 families have been recorded in this area, with about 90% of the taxa identified to species level. The richest families are Orchidaceae (86 spp.), Fabaceae (51 spp.) and Rubiaceae (42 spp.). Miconia and Solanum (14 spp. each), and Psychotria (13 spp.) are the richest genera. About 15% of the recorded species are endemic to the Atlantic Forest, and another 10% are disjunct between this area and the Amazon Rainforest. The results indicate that the Serra do Urubu is one of the richest areas in terms of number of species of the Atlantic Forest in the Northeast, and corroborates the Pernambuco Endemism Center.
