Abstract
Abstract: The Porto Ferreira State Park (PFSP) is located in the State of São Paulo southeastern Brazil, in an intriguing transitional area between the Atlantic Forest and Cerrado - both hotspots of biodiversity - represented mainly by the cerradão (CER), and the seasonal semideciduous forest (SSF), with its alluvial variation vegetation type (riparian forest - RP). Ecotonal areas play an important role in providing ecological and phytogeographic knowledge regarding the flora and vegetation of this region. Despite various studies on the PFSP, knowledge of this region remains fragmented. In this study, we aim to conduct an updated checklist of the PFSP vascular flora, including a compilation of all the studies conducted in this protected area, plus field work carried out by the authors from 2014 to 2017. In addition, given its ecotonal characteristics, we completed a floristic similarity analysis between the PFSP and other floristic surveys that examined the same vegetation types present in this study, to gain a better understanding of their phytogeographic relationships. Overall, 684 species, belonging to 387 genera and 107 families, were recorded. The SSF presented the richest vegetation type (478 species), followed by the CER (418) and the RP (231). The most diverse families were Fabaceae (64 species), Myrtaceae (41), Orchidaceae (39), Rubiaceae (37), Asteraceae (35), Bignoniaceae (26) and Malvaceae (20). Moreover, eight threatened species, at regional and national levels, were found. To date, 412 species have been added to the floristic list produced for the PFSP. The life forms with the highest number of species were trees (286 species), herbs (176) plus shrubs and subshrubs (123). Our research findings indicate floristic patterns with higher levels of similarity among species in geographical proximity, including those in ecotonal areas encompassing different vegetation types. These results rank the PFSP among some of the most species-rich conservation units with seasonal climates, and therefore is of great importance for plant conservation in the southeast of Brazil.

Abstract
Resumo Com base em dados publicados sobre a ocorrência de espécies de plantas vasculares no estado de São Paulo, avaliamos a performance das unidades de conservação (UCs) na proteção dessas espécies, considerando especialmente aquelas endêmicas do estado e as ameaçadas de extinção. Das 648 espécies de samambaias e licófitas no estado, 71% ocorrem em UCs, 10 são endêmicas de São Paulo e 30 estão ameaçadas de extinção. Pouco menos da metade das espécies de samambaias e licófitas ameaçadas não foram registradas em UCs, e três são endêmicas do estado. Para as plantas com semente, das 8.521 espécies registradas, 48% ocorrem em UCs, 361 são endêmicas do estado e 676 estão ameaçadas de extinção. Entretanto, 65% das espécies ameaçadas estão desprotegidas, e 51 destas são endêmicas do estado, a maioria nativa da Mata Atlântica. Muitas UCs ainda possuem grande lacuna de conhecimento sobre a flora, de esforço de coleta de material botânico e de registro em herbários, com destaque para as Reservas Particulares do Patrimônio Natural (RPPNs). Nossos dados reforçam a necessidade de ampliação de coletas botânicas em UCs, bem como a criação de novas áreas no estado, a fim de proteger espécies ameaçadas e endêmicas da flora paulista.
