Taxonomy and Classification

Thismia nigricoronata, a new species of Burmanniaceae (Thismieae, Dioscoreales) from Vang Vieng, Vientiane Province, Laos, and a key to subgeneric classification

“…He later proposed the new genus Scaphiophora (Schlechter 1921: 39) along with the new combination S. appendiculata (Schlechter 1918: 202) Schlechter (1921, highlighting the connate appendages of the perianth lobes as one of the main characters to differentiate Scaphiophora from Thismia (in which the perianth lobe appendages are free). Jonker (1938) accepted the new genus and added one more species, S. gigantea (Jonker 1938: 257), which was later transferred to Thismia as T. gigantea (Jonker 1938: 257) Hroneš (2014, following Merckx et al (2013) and Merckx & Smets (2014). This new combination has been accepted and followed thereafter (Govaerts et al 2007).…”

“…are a widely recognised family of mycoheterotrophic flowering plants (Chase et al 1995, Chase et al 2000, Woodward et al 2007, Merckx 2013, Merckx & Smets 2014, Truòng et al 2014. DNA analyses have indicated that the five genera typically included in tribe Thismieae, namely, Thismia Griffith (1845: 221), Afrothismia Schlechter (1906: 138), Oxygyne Schlechter (1906: 140), Haplothismia Airy Shaw (1952: 277) and Tiputinia Berry & Woodward (2007: 158), all fall outside Burmanniaceae (Merckx & Smets 2014), but their specific placement within the order Dioscoreales remains unclear (Merckx et al 2009, Merckx & Smets 2014.…”

Novitates Bruneienses, 9. A synopsis of Epirixanthes (Polygalaceae) in Brunei Darussalam and notes on species elsewhere

“…Epirixanthes Blume is a species-poor genus of holomycoheterotrophic herbaceous plants from the family Polygalaceae which inhabit the understorey of tropical rainforests (Van der Meijden, 1988;Merckx et al, 2013). It is sister to the autotrophic genus Salomonia Lour.…”

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).…”
