A subtribo Cranichidinae Lindl. (Orchidaceae) no Estado do Paraná, Brasil

Abstract

-(The subtribe Cranichidinae Lindl. (Orchidaceae) in the Paraná State, Brazil). The aim of this study was to describe the species of the subtribe Cranichidinae occurring in the Paraná State, due to the few information available about its flora. Eight species of Cranichidinae, originally collected in 38 localities, were found through the analysis of herbarium specimens. Cranichidinae are terrestrial herbs, with sessile to petiolate leaves, racemose inflorescence and non-resupinate flowers, usually green or white. Baskervilla Lindl. is represented only by B. paranaensis (Kraenzl.) Schltr.. Cranichis Sw. is characterized by a cochlear white and green spotted lip, and the genus is represented by C. muscosa Sw. and C. candida (Barb. Rodr.) Cogn.. Prescottia was the most diverse genus with five species, P. densiflora (Brongn.) Lindl., P. lancifolia Lindl., P. oligantha (Sw.) Lindl., P. montana Barb. Rodr. and P. stachyodes (Sw.) Lindl., and is recognized by a hooded lip with involute margins. Cranichidinae occurs mainly in Estepe Ombrófila and Floresta Ombrófila Densa. Baskervilla paranaensis, C. muscosa, P. lancifolia and P. montana are endangered species in Paraná. The lectotype of Cranichis candida, Prescottia epiphyta Barb. Rodr., P. microrhiza Barb. Rodr., P. pubescens Barb. Rodr. and P. nivalis Barb. Rodr. were designated herein. Prescottia epiphyta is a new synonym for P. lancifolia, and P. microrhiza and P. nivalis are new synonyms for P. oligantha.Key-words -Baskervilla, Cranichis, Flora of Paraná, IUCN, Prescottia RESUMO -(A subtribo Cranichidinae Lindl.

Oito espécies de Cranichidinae coletadas em 38 localidades foram encontradas a partir de análises de espécimes de herbários. Cranichidinae são ervas terrestres, com folhas sésseis a pecioladas, inflorescência racemosa e flores não ressupinadas, normalmente verdes ou brancas. Baskervilla Lindl., representada apenas por B. paranaensis (Kraenzl.) Schltr., possui labelo saciforme projetado para trás em bolsa arredondada e pétalas unguiculadas. Cranichis Sw. possui labelo cocleado, branco com manchas verdes, e o gênero é representado por C. muscosa Sw. e C. candida (Barb.Rodr.) Cogn.. Prescottia é o gênero mais diverso, com cinco espécies, P. densiflora (Brongn.) Lindl., P. lancifolia Lindl., P. oligantha (Sw.) Lindl., P. montana Barb. Rodr. e P. stachyodes (Sw.) Lindl., e pode ser reconhecido por possuir labelo calceolado com margens involutas. Cranichidinae ocorrem principalmente em Estepe Ombrófila e Floresta Ombrófila Densa. Baskervilla paranaensis, C. muscosa, P. lancifolia e P. montana são consideradas espécies ameaçadas no Paraná. Cranichis candida, Prescottia epiphyta Barb. Rodr., P. microrhiza Barb. Rodr., P. pubescens Barb. Rodr. e P. nivalis Barb. Rodr. tiveram seus lectótipos determinados. Prescottia epiphyta é considerada como sinônimo novo de P. la...

Bioecological Assessment of the State of the Adventitious Fraction of the Dendroflora of Recreational and Park Landscapes (Dnipro)

“…However, during the operation of recreational facilities, in the absence of constant care, there is a gradual decrease in the viability of plantations (Skrobala, Diniljuk, 1996). In this connection, the spread of invasive species to new territories is the greatest threat to global biodiversity, and we are already talking about biological invasions here (Macagnan et al, 2011), which can become a problem for the conservation of aboriginal species (Dongli et al, 2022;de Barros Ruas et al, 2022). The aim of the work is the bioecological analysis of the adventitious fraction of dendroflora and its diversity within recreational and park landscapes using the example of Kyrylivka Park (Dnipro, Ukraine).…”

First record of the genus Cranichis Sw. (Orchidaceae) for the state of Pará, Brazil

“…Cranichis muscosa is distributed from South Florida to South Brazil (WCSP, 2013), being cited for Brazil in Amazonas, Paraná, and São Paulo (Macagnan et al, 2011;Barros et al, 2013), and is here recorded for the first time Figure 1. Map of geographic distribution of Cranichis in Brazil.…”
