First record of Gymnosiphon tenellus (Benth.) Urb. (Burmanniaceae) in Paraná state and southern Brazil

Abstract

Gymnosiphon tenellus (Bentham) Urban is recorded for the first time in the state of Paraná and in southern Brazil. Until now it has only been known to occur in Central America, the Amazonian Rainforest, and in the Atlantic Rainforest of the state of Rio de Janeiro in southeastern Brazil. An updated description is provided, along with original, detailed pictures of the species.

Thismia panamensis (Standl.) Jonker (Thismiaceae): first record for southern Brazil

“…Another species of mycoheterotrophic plant has recently been recorded in the same conservation area, signaling that the mycoheterotrophic flora of Paraná state may still be underestimated and that additional studies of mycoheterotrophic plants should be conducted at Parque Estadual Serra da Baitaca and in the Serra do Mar mountain range (Souza et al 2019). The occurrence of T. panamensis in the Cfb climate (according to the Köppen system) suggests that the distribution of this species may extend further south in tropical rainforests under 1000 m (Köppen 1948;Roderjan 1994;Maack 2012;Alvarez et al 2013).…”

“…Such habits may account for their poor documentation, with several species having been recorded only once (e.g., Thismia macahensis (Miers) F.Muell. and T. prataensis) and other species having significant gaps between records (e.g., Thismia neptunis Beccari, rediscovered after 151 years: Sochor et al 2018) (Maas et al 1986;Souza et al 2019). Some species of Thismia, along with other mycoheterotrophic plants like Dictyostega Miers and Gymnosiphon Blume (Burmanniaceae), have wide and remarkably disjunct distributions, which have usually been interpreted as an indication of their families' great antiquity (Jonker 1938;Leake 1994;Merckxet al 2008).…”

Lacandonia brasiliana A. Melo & M. Alves (Triuridaceae), New Occurrence for the State of Ceará, Brazil

“…In the Southeastern region, we have representatives from Burmanniaceae (Souza, Blum, & Brotto, 2019), Thismiaceae (Guilherme, Coelho, Smidt, Gomes, & Souza, 2016), Orchidaceae (Bittencourt & Gasper, 2016;Mancinelli & Quadros, 2016). In the South region we have studies with the family Triuridaceae (Valadares, Arçari, Martins, & Schneider, 2015).…”

New records of four tree species in the state of Paraná, southern Brazil: Canellaceae, Lauraceae, Melastomataceae, and Myristicaceae

“…estimated about 6,430 species of native vascular plants in Paraná, including 5,990 angiosperms, 436 ferns and lycophytes, and four gymnosperms. However, this number has gradually been increased as new records are made Goldenberg 2014, 2016;Lozano et al 2016Lozano et al , 2018Brotto et al 2019;Souza et al 2019;Pereira et al 2021).…”
