DOI: doi.org/10.5852/ejt.2026.1034.3141AbstractTwo new species, Melastoma calcicolum Souvann. & Tagane sp. nov. and M. souladethianum Souvann. & Nob.Tanaka sp. nov. (Melastomataceae), are described from limestone karst habitats in Khammouane Province, central Laos. Descriptions, photographs, distribution, habitat, phenology, and initial conservation statuses of both newly described species are given. A key to the species of Melastoma in Laos including currently reported species is provided. These discoveries result from extensive fieldwork conducted between 2022 and 2025 in protected areas including Phou Hin Poun National protected area and Phou Pha Marn area. M. calcicolum sp. nov. is distinguished from M. saigonenese by its terete twigs, narrow lanceolate leaves, spaced penicillate emergences on the hypanthium, stalk of emergences on hypanthium shorter, glabrous sepals, and longer styles, while M. souladethianum sp. nov. differs from M. pellegrinianum by its terete branches, small inflorescences with 2–4 flowers, and sparsely bristled hypanthium with strigose hairs. Both species are currently known only from their type localities, occurring in exposed limestone areas, and are preliminarily assessed as Endangered and Critically Endangered based on IUCN criteria due to their restricted distributions and small population sizes. These findings highlight the high botanical diversity and endemism of Laos’s limestone ecosystems and underscore the importance of continued botanical exploration in the region.Keywords: Limestone flora, Myrtales, new description, new taxa, Southeast Asia Melastoma calcicolum Souvann. & Tagane sp. nov.

Reconstructed ancient enzymes reveal how cannabis evolved specialized cannabinoid production while offering new tools for biotechnology and medicine. Where do familiar cannabis compounds such as THC, CBD, and CBC come from? Scientists at Wageningen University & Research have shown for the first time, through direct experiments, how cannabis evolved the ability to make these cannabinoids. [...]

Research-backed adoption of high-oleic soybeans is improving milk quality and lowering costs for Michigan dairy farms. At first look, the 400 acres of soybeans on the Preston family’s dairy farm in southern Michigan appear no different from any other field. In reality, the crop reflects a research partnership with Michigan State University that is cutting [...]

[A–D] Caridina maeklongensis Macharoenboon, Manonai & Jeratthitikul. 2024[E, F] C. sumatrensis De Man, 1892RAFFLES BULLETIN OF ZOOLOGY. 72Abstract. A newly discovered landlocked shrimp, Caridina maeklongensis, new species, is described from the Mae Klong Basin, western Thailand. The morphology of the new species resembles C. sumatrensis, from which it differs in possessing a shorter rostrum with fewer dorsal teeth, a small number of very large-sized eggs, and a greatly reduced posteromedian projection on the distal end of the telson. The molecular evidence of the mitochondrial 16S rRNA gene also supports the species status of the newly described species. This is the fifth endemic species of Caridina known from Thailand.
