wo new species of Melastoma L.(Melastomataceae) from Limestone Karst, Khammouane Province, central Laos
Two new species, Melastoma calcicolum Souvann. & Tagane sp. nov. and M. souladethianumSouvann. & 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 Melastomain Laos including currently […]
Five New Records of Cyperaceae for the Flora of Laos
Five species of Cyperaceae, Carex breviscapa, Carex cryptostachys, Cyperus trialatus, Fimbristylis kernii, and Mapania enodis, are recorded for the first time in Laos, the first of which was obtained from our field survey in central Laos and the latter four were confirmed during specimen surveys in the herbaria FOF and KAG. Among them, Mapania is […]
Three new records of Curcuma subgen. Ecomatae (Zingiberaceae: Zingibereae) for the flora of Laos
Three species of Curcuma subgen. Ecomatae, Curcuma bicolor, C. nakhonphanomensis and C. rubroaurantiaca, are newly recorded for the flora of Laos. Descriptions and colour plates, as well as notes on ecology and phenology, are provided for all three species. In addition, a key to species of Curcuma subgen. Ecomatae in Laos is also provided.
Studies on the Gesneriaceae in Laos II: Lysionotus calcicola, a new species from limestone karsts in north and central Laos, supported by morphological and molecular evidence
A new species of Gesneriaceae, Lysionotus calcicola Phonep., Soulad. & Souvann., is described and illustrated based on morphological and molecular evidence. This species is distributed in limestone karsts in the Luangprabang, Vientiane and Khammouane provinces in northern and central Laos. The new species can be distinguished from the hitherto known species in the genus by […]
Orophea phouphamarnensis (Annonaceae), a new species from limestone karst in central Laos
In Southeast Asia, approximately 408,000 km2 is covered with limestone, most of which was originally fragmented in distribution (Clements et al. 2006). In Laos, the limestone area is about 30,000 km2, covering ca. 12.6% of land in northern and central Laos. Khammouane Province, central Laos, is one of the core sites of limestone in the […]
Gomphandra laotica (Stemonuraceae), a New Species from Central Laos
A new species of Gomphandra, G. laotica Soulad., V.S.Dang & Tagane (Stemonuraceae) is described from central Laos. It is characterized by its capitate inflorescences, 7–12 pairs of secondary veins, densely strigillose petioles, and glabrous stamens, by which combination it is clearly distinguished from the other species of Gomphandra in the region
Grewia souladethiana, a new species of Malvaceae from Laos
Grewia souladethiana (Malvaceae-Grewioideae) is described and illustrated from Phou Hin Poun National Park, Khammouane Province, in central Laos. The new species grows at the edge of evergreen broad-leaved forest and in open grassland on the foot of limestone hills. To confirm the validity of the new species, diagnostic morphological characters were compared based on literature […]
Systematics, Ecology and Management of Rattans in Cambodia, Laos and Vietnam. (The Biological Bases of Sustainable Use)
The Greater Mekong region is one of the most biologically diverse places on the planet. Home to the world’s largest freshwater fish species and extensive tiger habitat, its forests, rivers, grasslands and wetlands pulse with life. About 80 per cent of the region’s 300 million people depend directly on the goods and services its ecosystems […]
Morphological and Molecular Variation in Tylototriton (Caudata: Salamandridae) in Laos, with Description of A New Species
The salamandrid genus Tylototriton is poorly known in Laos, with one described species and unverified reports of two others. We undertook new fieldwork and obtained samples of Tylototriton at six localities across northern Laos during 2009–2013. Bayesian phylogenetic analysis of mitochondrial DNA, principal component analyses of 13 mensural characters, and qualitative morphological comparisons with samples […]
