<div>Orchidaceae in Santa Catarina: Update, geographic distribution and conservation</div>

Abstract

This study consists of a checklist and an analysis of the spatial distribution of the species of Orchidaceae of the Brazilian state of Santa Catarina. Based on literature, the accepted names and current synonyms for the species in the state are cited. The occurrence of 121 genera and 560 accepted species was detected, 12 of them endemic. Of the three subfamilies represented in the state, Epidendroideae is the most representative, with 94 genera and 432 species, followed by Orchidoideae with 25 genera and 122 species, and Vanilloideae, with only two genera and six species. According to the criteria of the International Union for Conservation of Nature, 24 species fall within the vulnerable category, seven are endangered and four are critically endangered. The life form, plant formation and habitat of each species are also presented.

Anatomical study of Orchidaceae epiphytes species occurring in indigenous territory in the Parque Estadual da Serra do Tabuleiro (P.E.S.T.), Santa Catarina, Brazil

“…The family Orchidaceae is the second largest angiosperm family, in number of species, and includes 736 genera in five subfamilies (Chase et al 2015). The most derived and richest subfamily is Epidendroideae, which includes approximately 650 genera and 18,000 species (Dressler 2005;Siqueira et al 2014). Orchidaceae are herbaceous, sometimes mycoheterotrophic, and can be epiphytic (73% of the species in the family), hemiepiphytic, terrestrial or rupicolous (Koch et al 2014).…”

“…In Brazil, orchids are present on the indigenous culture, such as in Guarani traditional histories, and also as a source of income through the commercialization of orchid species by Guarani indigenous people in the southern part of the country (Stehmann et al 2009;Siqueira et al 2014;Blanco 2017). In the urban centers of south Brazil, Guarani groups acquire part of their income commercializing handicrafts and living plants, mostly orchids.…”

PROPAGAÇÃO IN VITRO DE Coppensia ranifera (LINDL.) F. BARROS & V.T. RODRIGUES (ORCHIDACEAE)

“…Orchidaceae é umas das famílias botânicas com a maior biodiversidade dentre as angiospermas, com cerca de 25.000 espécies, com grande ocorrência nas regiões neotropicais (WANGLER et al, 2015). No Brasil, existem registradas 2539 espécies de orquídeas (BARROS et al, 2016) e em Santa Catarina cerca de 560 espécies (SIQUEIRA et al, 2014), dentre elas Coppensia ranifera (Lindl.) F. Barros & V. T. Rodrigues (sinônimo Gomesa ranifera (Lindl) M. W. Chase & N. H. Williams) (BARROS et al 2016).…”

“…A técnica "thin cell layer" tem sido usada para diversas espécies de orquídeas no cultivo in vitro, como em Cymbidium spp. TANAKA, 2006;TANAKA, 2009;HOSSAIN et al, 2010), Dendrobium gratiosissimum (JAIPHET; RANGSAYATORN, 2010), Coelogyne cristata (NAING et al, 2011), Paphiopedilum (LIAO et al, 2011), Renanthera Tom Thumb 'Qilin' (WU et al, 2012), Brasilidium forbesii (GOMES et al, 2015).…”

Novelties in the orchid flora of the Municipality of Benedito Novo, Santa Catarina, Brazil, and an updated checklist

“…There are few studies with Orchidaceae for the state of Santa Catarina (Favretto & Geuster 2011, Reis et al 2011, Siqueira, Zanin & Menini Neto 2014, and the most important research, conducted between 40 and 60 years ago, focused on the capital Florianopolis and its surroundings (Rohr 1951, Pabst 1951, 1952, 1953, 1954, 1956, 1957, 1959, Klein, Bresolin & Reis 1977/1978. A vegetation inventory of the Itajaí Valley, including 200 orchid species, was published by Klein (1979).…”
