“…The split between the two genera of Begoniaceae, Begonia and Hillebrandia, is estimated as 29 (41-18) Myr old, roughly the age of the Hawaiian archipelago (ca 30 Myr), where Hillebrandia is endemic (Clement et al 2004 figure 2).…”

Knowing the geographical origin of economically important plants is important for genetic improvement and conservation, but has been slowed by uneven geographical sampling where relatives occur in remote areas of difficult access. Less biased species sampling can be achieved when herbarium collections are included as DNA sources. Here, we address the history of Cucurbitaceae, one of the most economically important families of plants, using a multigene phylogeny for 114 of the 115 genera and 25 per cent of the 960 species. Worldwide sampling was achieved by using specimens from 30 herbaria. Results reveal an Asian origin of Cucurbitaceae in the Late Cretaceous, followed by the repeated spread of lineages into the African, American and Australian continents via transoceanic long-distance dispersal (LDD). North American cucurbits stem from at least seven range expansions of Central and South American lineages; Madagascar was colonized 13 times, always from Africa; Australia was reached 12 times, apparently always from Southeast Asia. Overall, Cucurbitaceae underwent at least 43 successful LDD events over the past 60 Myr, which would translate into an average of seven LDDs every 10 Myr. These and similar findings from other angiosperms stress the need for an increased tapping of museum collections to achieve extensive geographical sampling in plant phylogenetics.

“…However, comparing the floristic checklists of Usina São José and Serra do Urubu, this assertion is not confirmed. It is noteworthy that some families such as Bignoniaceae and Polygalaceae are more diverse in lowland forests , unlike Gesneriaceae and Begoniaceae that are richer in middle and high elevation areas (Clement et al 2004;Perret et al 2013). Piperaceae is another example of the richness of the flora of Serra do Urubu being more pronounced in higher altitude forests than in lowland forests (Guedes 1998;Sacramento et al 2007;Soares Jr. et al 2008;Alves et al 2013).…”

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.

“…O gênero Begonia possui aproximadamente 1.400 espécies e está amplamente distribuído nas regiões tropicais e subtropicais do mundo (Clement et al 2004;Forrest et al 2005;Forrest & Hollingsworth 2003), ausente apenas na Australásia (Heywood et al 2007). No Brasil, o gênero está representado por cerca de 200 espécies, distribuído em todas as formações vegetais, excetuando-se os manguezais.…”

RESUMO(Begonia lunaris E.L.Jacques (Begoniaceae), uma nova espécie para o estado do Rio de Janeiro, Brasil) Uma nova espécie de Begonia, endêmica da mata atlântica do Brasil, é descrita e ilustrada. Begonia lunaris é conhecida somente da sua localidade típica, Estação Ecológica Estadual do Paraíso, localizada nos municípios de Guapimirim e Cachoeiras de Macacu, Rio de Janeiro, Brasil (22º2'-22º32'S e 42º50'-42º56'W), crescendo próxima às margens dos rios. Destaca-se prontamente das demais espécies brasileiras do gênero por apresentar alas da cápsula inflexas, flores alaranjadas a vermelho-alaranjadas e folhas semi-lunares. Caracteres diagnósticos, descrição, ilustração detalhada e comentários taxonômicos são fornecidos e suas afinidades são discutidas. Palavras-chave: taxonomia, mata atlântica, endemismo. ABSTRACT(Begonia lunaris E.L.Jacques (Begoniaceae), a new species from the state of Rio de Janeiro, Brazil) A new narrow endemic species of Begonia from the Atlantic rain forest of Brazil is described and illustrated. Begonia lunaris is known only from the type locality, Estação Ecológica Estadual do Paraíso, localized in the Municipality of Guapimirim and Cachoeiras de Macacu, Rio de Janeiro, Brazil (22º26'-22º32'S e 42º50'-42º56'W), growing near rivers. It promptly differs from the other Brazilian species of the genus in having wings of the capsule bent inwards, orange to orange-red flowers and crescent-shaped leaves. Diagnostic characters, description, detailed illustration and taxonomic comments are given and its relationships are discussed.
