A new Mesozoic fossiliferous locality was discovered in the Mae Sot Basin, Western Thailand. Ginglymodian fish scales and bones are reported, as well as fossil wood (Agathoxylon sp.) and leafy twigs (cf. Watsoniocladus sp.). These are associated to Skolithos and Scoyenia ichnofacies. This limited fossil record makes biogeographical comparisons and...
Petrified trunks in Mueang Kamphaeng Phet District, upper Central Thailand, were unearthed in Quaternary deposits on the western rim of the Ping River. The sediments consist mainly of semi-consolidated gravel, sand, silt, and clay, indicating that the woods were transported by the ancient Ping River. Macro-scopic features revealed that preservation...
This work aims to investigate the geodiversity of the Khorat Geopark area, northeastern Thailand, and assess the geological sites that are connected to biological and cultural heritage, as well as community activities that enhance geoconservation and sustainable development. The geological diversity of Khorat Geopark dates back to the late Jurassic...
Identifying and protecting refugia is a priority for conservation management under projected anthropogenic climate change. We have two main objectives: the first is to explore the spatial (East Asia) and temporal (Last Glacial Maximum to year 2070) distribution patterns of dominant Castanopsis species of evergreen broad-leaved forests, also the rel...
Five fossil endocarps were collected from late Miocene fluvial deposits in a commercial sandpit in
Northeastern Thailand. The endocarps were studied with light microscopy and scanning electron microscopy
(SEM) and compared with recent and fossil endocarps. We conclude that the endocarps are Parinari (Chrysobalanaceae)
and propose two new species, P...
Pinus macrofossils were recovered from three Cenozoic basins in Thailand, a genus previously known in Thailand almost exclusively from pollen. Nong Ya Plong Basin, Phetchaburi Province, Central Thailand yielded shoots with 5-needled fascicles, proposed as a new species, Pinus nongyaplongensis Grote in the subgenus Strobus. Two seed cones were found...
The remains of an ancient wooden ship were found in a shrimp farm in Samut Sakhon Province, central Thailand, in 2013. The remains, referred to as the Phanom-Surin shipwreck, are thought to be from the ninth century CE. The objective of this project was to investigate ropes from the shipwreck by comparative scanning electron microscopy in an attemp...
Pinus (Pinaceae) is the largest genus of the conifers, characterised by needle-leaves usually in fascicles of 2–5 and seed cones with highly specialised and diversified apophyses and umbos. Although a denticulatomucronate umbo is the most common umbo type in the subsection Pinus, genus Pinus, this type has not been well documented in the fossil rec...
Large areas of Earth’s continents were covered by temperate forests before the dramatic increase of the human population in the past two millennia. Prior to human expansion, temperate forests were more extensive in the Neogene (23–2.6 Ma) when climate at the middle latitudes was slightly warmer and more equable than at the present. These temperate...
A checklist of Acanthaceae subfamily Nelsonioideae in Thailand is presented. Two genera (Nelsonia and Staurogyne) and 29 species
are considered native to Thailand, including new species Staurogyne kaengkrachanense. Ecological and distributional data, together
with a key to the species, are provided.
In the original version of this Article, an incorrect sample size was provided for the number of relict species (443 instead of 442) and the number of relict forests (423 instead of 422). These errors have been corrected in both the PDF and HTML versions of the Article.

Today East Asia harbors many “relict” plant species whose ranges were much larger during the Paleogene-Neogene and earlier. The ecological and climatic conditions suitable for these relict species have not been identified. Here, we map the abundance and distribution patterns of relict species, showing high abundance in the humid subtropical/warm-te...
A checklist of the genus Pseuderanthemum in Thailand is presented, including ecological data, distributional information and
specimen citations. Sixteen taxa are recognized, of which 11 taxa are native and five are introduced, including two new species;
Pseuderanthemum thailandicum T.Choopan & P.J.Grote and P. lanceophyllum T.Choopan. A key to the...
The pollen morphology of Thai Acanthaceae Subfamily Nelsonioideae was investigated. The pollen type was tricolpate. Their apertures were longitudinal narrow colpi with acute ends. The polar axis length (P) was 16.342.5 μm and equatorial axis length (E) was 17.537.5 μm. The largest size was represented in Staurogyne dispar, while the smallest show...
The Khorat Plateau, at the centre of mainland Southeast Asia, is considered a bridge connecting the biotas of Indochina and Kalimantan. The vegetation change in this area is an indicator of regional environmental change, but the history is unclear. In this study, a sand pit along an ancient fluvial terrace on this plateau was investigated palynolog...
Fluorescence analysis of modern pollen grains is a well-established technique, but its use on fossil material is significantly less prevalent. A study focused on pollen and spore fluorescence and its indication was carried out using samples collected from a 14-m-deep exposed section at an abandoned fluvial terrace in the Khorat Plateau, the center...
The morphology and distribution of calcium carbonate crystals or cystoliths in mature leaves of fifteen taxa, included 2 exotic species of the genus Pseuderanthemum (Acanthaceae) in Thailand were studied. All studied taxa contained calcium crystals. The size of cystoliths varied even in the same species. The crystals ranged from 65 m to 300 m in...
Arthur Francis George Kerr’s life is reviewed and related to a previously published account. Kerr’s collecting activity is analysed using an expanded version of the Thai Biogeography Group’s database of collections. 8,666 of the total 48,970 collections are Kerr’s and 3,178 are those of his colleagues and friends. Therefore, the total number of col...
Pseuderanthemum pubescens T. Choopan & P. J. Grote, a new species from southeastern Thailand is described and illustrated. It is distinguished from P. longistylum J. B. Imlay by leaves being pubescent instead of glabrous and by the corolla lobes being purple with reddish purple dots on all 5 lobes instead of dotted on lower lip only.
