Thismia mucronata (Thismiaceae), a new species from Southern Vietnam

Abstract

Thismia mucronata, a new species of Thismiaceae, is described and illustrated. The species was discovered in 2013 during a botanical survey of a forest in the vicinity of Bao Loc town (Lam Dong province, Southern Vietnam). Thismia mucronata is characterised by vermiform roots and mitriform inner tepals. It differs from related species mainly by the short and appressed to each other appendages of inner tepals, which together resemble a short mucro, the narrow mitre without foveae, the almost horizontal annulus and the absence of interstaminal glands. A key to Vietnamese species of Thismia is provided.

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

“…The genus has received a lot of botanical interest lately with the publication of 16 new species from Asia and the Pacific (Thiele & Jordan 2002, Yang et al 2002, Tsukaya & Okada 2005, Larsen & Averyanov 2007, Chantanaorrapint 2008, Chiang & Hsieh 2011, Chantanaorrapint 2012, Tsukaya & Okada 2012, Dančák et al 2013, Li & Bi 2013, Nuraliev et al 2014, Truòng et al 2014, Mar & Saunders 2015, Nuraliev et al 2015, Chantanaorrapint & Sridith 2015, as well as several new records (Chantanaorrapint & Sridith 2007, Chantanaorrapint & Chantanaorrapint 2009, Ho et al 2009) in the last 15 years alone.…”

Flora of Bokor National Park VII: Thismia bokorensis (Burmanniaceae), a new species representing a new generic record

“…Considering that the majority of these species were collected only once (Jonker 1948), and that many new species have recently been discovered, especially from various Southeast Asian countries (e.g., Tsukaya & Okada 2012, Dančák et al 2013, Nuraliev et al 2014, Truong et al 2014, Chantanaorrapint & Sridith 2015, Li & Bi 2013, Hroneš et al 2015, many more undescribed species are probably still hidden in the tropical rain forests of Southeast Asia.…”

Thismia panamensis: first record of Thismiaceae for the Brazilian Cerrado in Goiás state

“…consists of ca. 54 achlorophyllous mycoheterotrophic herbaceous plants, typically growing among leaf litter on the shady wet forest floor (Maas et al 1986;Nuraliev et al 2014). The genus has a Pantropical distribution with two main centers of biodiversity: Southeast Asia and the Atlantic Rain Forest of South America (Jonker 1948;Mancinelli et al 2012).…”
