A New and Threatened Species of Passiflora Section <I>Decaloba</I> (Passifloraceae) from Minas Gerais State, Brazil

Abstract

ResumoO presente estudo teve como objetivo caracterizar a flora fanerogâmica da região da Serra Negra localizada no sul da Zona da Mata de Minas Gerais, entre os municípios de Lima Duarte, Rio Preto, Santa Bárbara do Monte Verde e Olaria. Embora considerada de importância biológica alta, esta região não possui nenhum registro anterior de dados florísticos, o que levou ao desenvolvimento deste levantamento, durante o período de 2003 a 2010. A vegetação é caracterizada por um mosaico de formações florestais e campestres onde se destacam os campos rupestres e florestas nebulares em altitudes que variam de 1300 a ca. 1700 m. Um total de 1033 espécies foi encontrado, distribuídas em 469 gêneros e 121 famílias sendo as mais representativas Orchidaceae (115 spp.), Asteraceae 54 spp.), Melastomataceae (56 spp.), Myrtaceae (53 spp.), Fabaceae, Poaceae e Rubiaceae (48 spp. cada), Bromeliaceae (43 spp.), Solanaceae (38 spp.) e Piperaceae (33 spp). Novos registros e endemismos para a flora mineira foram encontrados e 58 espécies estão citadas na lista de espécies ameaçadas de Minas Gerais.

AbstractThe present study aims to characterize the phanerogamic flora of the region of Serra Negra, located in the southern of Zona da Mata of Minas Gerais, between the municipalities of Lima Duarte, Rio Preto, Santa Bárbara do Monte Verde and Olaria. Although this region is considered of high biological importance, it has no previous record of floristic data, which led to the development of this survey, during the period 2003 to 2010. The vegetation is characterized by a mosaic of forests and grassland, especially cloud forests and "campos rupestres" (rocky grasslands), occurring at altitudes between 1300 to 1700 m. A total of 1033 species was recorded, distributed in 469 genera and 121 families. The most representative families are Orchidaceae (115 spp.), Asteraceae 54 spp.), Melastomataceae (56 spp.), Myrtaceae (53 spp.), Fabaceae, Poaceae e Rubiaceae (48 spp. cada), Bromeliaceae (43 spp.), Solanaceae (38 spp.) and Piperaceae (33 spp). New records and endemic species to flora of Minas Gerais were found and 58 species are cited in the list of endangered species of Minas Gerais.

Pliocene seeds of Passiflora subgenus Decaloba (Gray Fossil Site, Tennessee) and the impact of the fossil record on understanding the diversification and biogeography of Passiflora

“…Comparisons to modern Passiflora seeds with ridged‐and‐sulcate sculpture were made on the basis of direct observation and the extensive literature documenting Passiflora seed morphology, which includes photographs, drawings, and descriptions (Killip, 1930, 1938; Wiggins, 1970; Porter, 1982; Jørgensen et al, 1987; Escobar, 1989; MacDougal, 1989a, 1989b, 1995, 2001a, 2004, 2006, 2011, 2013; Jørgensen and MacDougal, 1997; J.

Passifloraceae sensu stricto de Minas Gerais, Brasil

“…É semelhante a P. pohlii, porém esta difere-se por apresentar lâminas foliares sem oceolos. A ilustração da espécie pode ser encontrada em Bernacci et al (2014, fig. 1).…”

Passifloroideae from coastal Piauí, Brazil

“…and Passiflora L. (Bernacci, 2003; Cervi, 2005; Silva et al, 2013), together comprising 161 species (89 endemic). The plants are diverse in habit, including trees, shrubs, sub‐shrubs, climbing vines and lianas (Bernacci et al, 2014; “Passifloraceae in Flora do Brasil 2020 em construção”, 2020) and are most characteristically woody or herbaceous vines with axillary tendrils, alternate leaves, extrafloral nectaries, petiolar glands, axillary flowers with an extra‐ staminal filamentous corona and an androgynophore, and berry or capsule type fruits (Joly, 2002; Bernacci, 2003; Milward‐de‐Azevedo & Valente, 2004).…”

“…Taxonomic studies of Passifloroideae have already been carried out in some Brazilian states and regions of Brazil, such as Amazonia (Souza & Hopkins, 2011; Cervi & Linsingen, 2010; Koch et al, 2015; Mezzonato‐Pires et al, 2016), southeast of Pará in the Serra dos Carajas (Koch & Ilkiu‐Borger, 2016), Mato Grosso (Cervi & Imig, 2013; Mezzonato‐Pires, Silva & Oliveira, 2021; Silva et al, 2013), Mato Grosso do Sul (Koch et al, 2019), São Paulo (Groppo & Pirani, 2005), Espírito Santo (Imig & Cervi, 2014; Ferreira et al, 2007; Borges & Milward‐de‐Azevedo, 2017), Minas Gerais (Bernacci et al, 2014; Cervi & Imig, 2013; Imig et al, 2018), Paraíba (Tölke et al, 2011) and the Chapada do Araripe in northeast Brazil (Souza, Silva & Loiola, 2021). Passiflora is the most species‐rich genus (153 species, 85 endemics), and is widely distributed (“Passiflora in Flora do Brasil 2020 em construção,” 2020).…”
