Thismia gigantea, a new combination in Thismia (Thismiaceae)

Abstract

Thismia Griffith (1844: 221; Thismiaceae J. Agardh, 1858: 99) comprises about 55 species (e.g. Tsukaya & Okada 2012; Dančák et al. 2013; Lưu et al. 2014). The greatest species diversity is situated in southeastern Asia and in the northern parts of South America (Merckx et al. 2013). Both morphological and molecular data suggest that the genus is not monophyletic being represented by at least two evolutionary lineages, the neotropical Thismia subg. Ophiomeris (Miers) Maas & H.Maas (1986: 144) and the rest of the species in a broadly defined subg. Thismia (Merckx et al. 2006; Merckx & Smets 2014).

Thismia tectipora (Thismiaceae) a new, unusual mitre-form species from tropical Australia

“…Stone 1980;van Steenis 1982;Maas et al 1986;Maasvan de Kamer 1998;Thiele & Jordan 2002;Mabberley 2008;Chantanaorrapint & Chantanaorrapint 2009;Imhof 2011;Hroneš 2014), though Govaerts et al (2013) has a contrasting view. As currently generally accepted, Thismia also includes the segregate Asian genera Sarcosiphon and Scaphiophora (Maas et al 1986;Maas-van de Kamer 1998;Mabberley 2008;Hroneš 2014).…”

Thismia brunneomitra, another new species of Thismia (Thismiaceae) from Ulu Temburong, Brunei Darussalam

“…Currently, almost 60 species are recognized in the genus (Hroneš 2014, Hunt et al 2014, Mar & Saunders 2015. Species of Thismia have scattered distribution through the (sub-)tropical areas of the Asia, Australia, New Zealand and South America (Jonker 1938, Maas et al 1986, Hunt et al 2014.…”

Thismia nigricans Chantanaorr. & Sridith, a new species of Thismiaceae from Southern Thailand

“…It comprises about 55 species of mycotrophic herbs (e.g. Hroneš 2014;Merckx & Smets 2014;Hunt et al 2014;Mar & Saunders 2015) and is distributed mainly in tropical Asia and America with a concentration of species in Southeast Asia (Jonker 1938;Maas et al 1986;Merckx et al 2013 ). In the last decade, several new species of the genus have been described from South-East Asia (Tsukaya & Okada 2005, 2012Larsen & Averyanov 2007;Chantanaorrapint 2008Chantanaorrapint , 2012Dančák et al 2013;Nuraliev et al 2014;Truong et al 2014).…”
