MACAGNAN, Tomas André; SMIDT, Eric de Camargo e AZEVEDO, Cecília Oliveira de. The subtribe Cranichidinae Lindl. (Orchidaceae) in the Paraná State, Brazil. Rev. bras. Bot. [online]. 2011, vol.34, n.3, pp. 447-461. ISSN 0100-8404. http://dx.doi.org/10.1590/S0100-84042011000300017.
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.
