“…As Laos has the lowest collection density in Southeast Asia, new collection programmes inevitably reveal previously unknown species and new records in Laos. For example, among the 181 plant taxa collected from Nam Kading National Protected Area, Bohlikamxai Province, eight species (4.4%) were found to be new to science (Souladeth et al, 2017(Souladeth et al, , 2019Tagane et al, 2018a;Souvannakhoummae et al, 2019;Yang et al, 2018) and 30 species (16.5%) were found to be new records in Laos (Tagane et al 2018b). In 2019, Phetlasy Souladeth (FOF) began a two-year project to document the plant diversity of the Bolaven Plateau, Champasak Province, Attapeu Province and Sekong Province, in collaboration with Kagoshima University, Japan, and a similar trend is being found.…”

is a region of high plant diversity with an estimated 50,000 flowering plant species. Estimates of plant diversity in the region continue to grow as large numbers of new species are described even though there have been suggestions that there are few new species to be Gard. Bull. Singapore 71 (2) 2019 268 found in some parts of Southeast Asia. It is likely that most estimates of species numbers in the countries of Southeast Asia are too low due to the lack of taxonomic work on groups which have many locally endemic species. Differing collecting densities across the region can profoundly affect our understanding of plant diversity and lead to large underestimates of species diversity in poorly collected countries and regions.

“…Since 2015, we have conducted eight field surveys to assess the Lao flora, and accumulated a total of 3,460 specimens collected from Nam Ha National Protected Area (NPA), Nam Kading NPA, Phou Khao Khuoay NPA, and Dong Hua Sao NPA. Using these materials, previously we reported 79 vascular plant species new to the flora of Laos including 18 new species in 11 families (Souladeth et al, 2017(Souladeth et al, , 2018(Souladeth et al, , 2019(Souladeth et al, , 2020(Souladeth et al, , 2021aSouvannakhoummane et al, 2018;Suetsugu et al, 2018;Tagane et al, 2018aTagane et al, , b, c, 2020aTagane et al, , b, 2021Tanaka et al, 2020;Yang et al, 2018;Nagahama et al, 2019).…”

Six pteridophyte species of five families and 12 spermatophyte species of 10 families are reported from Bolaven Plateau, southern Laos, as new records to the flora of Laos. Moreover, two new species, Sterculia bolavenensis (Malvaceae) and Wikstroemia bolavenensis (Thymelaeaceae), are described. For each species, voucher specimens are cited, photographs are shown and additional information including geographical distribution, ecology and taxonomic notes are provided.

“…The Nam Kading National Protected Area, located in the centre of Laos, has a diverse vascular flora yet remains undersurveyed. Floristic research was carried out in this area between 2017-2019, allowing the discovery and description of several new species (Souladeth et al, 2017(Souladeth et al, , 2019Tagane et al, 2018;Yang et al, 2018;Souvannakhoummane et al, 2019) as well records of various new taxa for the flora of Laos (Tagane et al, 2017). In a field survey in deciduous forest of this Protected Area, a population of Begonia characterized by beautiful red flowers, cane-like stems and variegated leaves with a dark red undersurface was observed.…”
