“…This pattern was also reported for FRA (Ferreira et al 2007) and CAG (Bovini et al 2014). Some species are widespread on those three sets of islands (e.g., Sesuvium portulacastrum, Temnadenia odorifera, Syagrus romanzoffiana, Cyrtocymura scorpioides, Cereus fernambucensis, Ipomoea cairica, Maranta divaricata, Guapira opposita, Sporobolus virginicus, Talinum paniculatum and Chiococca alba).…”

“…Species richness on QGI is lower than that on CAG (Bovini et al 2014) and close to that on FRA (an island of only 16 ha; Ferreira et al 2007) -which is apparently related to the distance of QGI from the coast, making the arrival and establishment of propagules more difficult. The very low richness on ABR (Kemenes 2003) can also be related to its greater distance from the coast.…”

“…Small island plant inventories are even more scarce (Kemenes 2003, Ferreira et al 2007, Bovini et al 2014). These studies have frequently indicated that the floras of coastal islands are basically composed of mainland Atlantic Forest complex species (sensu Oliveira-Filho & Fontes 2000, Scarano 2002, and are related to their recent histories of isolation from the mainland.…”

Studies of the vegetation on islands off the coast of southeastern Brazil are still very scarce, despite their importance for assessing, managing, and conserving insular biodiversity. We present here a list of the vascular flora of Queimada Grande Island (QGI; 24°29′10″ S, 46°40′30″ W, 57 ha, 33.2 km from the coast) in southeastern Brazil and describe its phytophysiognomies. The island is covered mainly by Atlantic Forest (Dense Ombrophilous Forest), as well as with rock outcrop and anthropogenic vegetation with herbaceous-shrub phytophysiognomies. QGI showed relatively low species richness (S = 125) when compared to other Brazilian coastal islands. Herbaceous (52) and climbing species (31) predominated on QGI. The richest families were Fabaceae (11 species), Poaceae (9), and Apocynaceae, Asteraceae and Orchidaceae (8 species each). Most species (S = 112) are autochthonous from different phytophysiognomies of the southeastern Brazilian Atlantic Forest complex. Many species associated with anthropically disturbed areas (S = 26) can be found on QGI, including the invasive grass Melinis minutiflora. There was a slight predominance of zoochory (S = 50). We did not identify any species endemic to QGI. One of its species (Cattleya intermedia, Orchidaceae) is vulnerable at both national and regional levels, and another (Barrosoa apiculata, Asteraceae) is presumably extinct on the mainland in São Paulo State. The vascular flora of QGI originated from the mainland Atlantic Forest complex, following the pattern of other coastal islands in southeastern Brazil. The flora and vegetation of QGI reflect the combination of insular conditions, the small size of the island, habitat restriction, steep topography, incipient soils, and the past use of the area with the introduction of several foreign species. We recommend permanent monitoring of the vegetation cover of QGI and its management, in order to ensure the conservation of the local native biota.

Flora vascular e vegetação da Ilha Queimada Grande, São Paulo, sudeste do BrasilResumo: Estudos sobre a vegetação de ilhas costeiras no sudeste do Brasil ainda são muito escassos, apesar de sua importância para a avaliação, manejo e conservação da biodiversidade insular. Nós apresentamos aqui uma lista da flora vascular da Ilha Queimada Grande (IQG; 24°29′10″ S, 46°40′30″ W, 57 ha, 33,2 km da costa), sudeste do Brasil, e descrevemos suas fitofisionomias. A ilha é recoberta principalmente por Floresta Atlântica (Floresta Ombrófila Densa), bem como por vegetação sobre afloramento rochoso e vegetação antrópica com fisionomias herbáceo-arbustivas. A IQG apresentou riqueza relativamente baixa (S = 125) comparada a de outras ilhas costeiras do Brasil. Espécies herbáceas (52) e trepadeiras (31) predominaram na IQG. As famílias mais ricas foram Fabaceae (11 espécies), Poaceae (9), Apocynaceae, Asteraceae e Orchidaceae (8 espécies cada). A maioria das espéc...
