Laeliinae (Orchidaceae) do parque nacional do Caparaó, Estados do Espírito Santo e Minas Gerais, Brasil

Abstract

-(Laeliinae (Orchidaceae) from Parque Nacional do Caparaó, Espírito Santo and Minas Gerais States, Brazil). This work aims to identify and characterize species of subtribe Laeliinae (Orchidaceae) occurring in the Parque Nacional do Caparaó, between Minas Gerais and Espírito Santo States. The vegetation in the area comprises forests and campos de altitude, occurring at around 2,000 m, and the highest peak is the Pico da Bandeira, the highest point in the Southeastern region of Brazil with 2,890 m. Laeliinae is represented in that area by five genera and a total of nineteen species:

Ecological data for an orchid diversity hotspot show that the subtribe Laeliinae may be endangered in the Brazilian Atlantic Forest

“…E. patens). The results of the present study corroborate data presented by Forster and Souza (2007). These authors reported that Encylia patens, Epidendrum armeniacum (widely distributed throughout South America) and E. secundum (throughout the Americas) are well represented in Caparaó.…”

“…The greatest diversity of Laeliinae in Brazil is found in the Atlantic Forest (Flora do Brasil 2020), and new species from this phytogeographic domain have frequently been described (Barberena and Gonzaga 2016). The richness of Laeliinae species in PARNA Itatiaia is higher than in other Brazilian Atlantic Forest remnants where taxonomic studies of the subtribe have been conducted (Barbero 2007, Forster and Souza 2007, Romanini and Barros 2007, Nardy et al 2016). Most of the Laeliinae species (73%) in PARNA Itatiaia are found exclusively in montane vegetation, whereas four species (12%) are restricted to upper montane forest and two species (Epidendrum chlorinum and E. secundum) occur in both phytophisiognomies.…”

“…These authors reported that Encylia patens, Epidendrum armeniacum (widely distributed throughout South America) and E. secundum (throughout the Americas) are well represented in Caparaó. Conversely, Forster and Souza (2007) classified C. bicolor, E. chlorinum, E. saxatile and at least six other taxa as rare or vulnerable to local extinction due to few individuals found or the absence of recent collections, even though recent attempts have been made to find them. Nardy et al (2016) highlighted human influence as a concern for the conservation of Laeliinae species.…”

Inventários florísticos na região do Caparaó Capixaba revelam novos registros para a flora do Espírito Santo

“…A baixa representatividade de coleções para a região do Caparaó é mais expressiva para a vertente capixaba, para a qual há apenas uma listagem florística de plantas vasculares disponível na literatura (Zorzanelli et al 2017). Os demais estudos da vegetação publicados até o presente momento para a região, foram realizados em localidades situadas no estado de Minas Gerais, por exemplo Leoni & Chautems (2004), Mazine & Souza (2008), Forster & Souza (2013) e Moraes et al (2014).…”

Verbenaceae no Parque Nacional do Caparaó, Serra da Mantiqueira, Brasil

“…Foster, G. Hatschbach, M. Brugger, L. Krieger, V. C. Souza e L. Leoni (Mota 2012). Em relação aos trabalhos taxonômicos sobre a flora do Caparaó, foram publicados tratamentos para vários grupos como: Violaceae (Souza & Souza 200), Plantaginaceae (Souza & Souza 2002), Ericaceae (Romão & Souza, 2003), Gesneriaceae (Leoni & Chautems 2004), Eriocaulaceae (Trovó et al 2006), Melastomataceae (Faria et al 2006), Myrtaceae (Mazine & Souza 2008), Begoniaceae (Feliciano et al 2010), Laeliinae-Orchidaceae (Forster & Souza 2013) e Bromeliaceae (Mota et al 2016).…”
