Introduction: Shrub promotes the survival, growth and reproduction of understory species by buffering the environmental extremes and improving limited resources (i.e., facilitation effect) in arid and semiarid regions. However, the importance of soil water and nutrient availability on shrub facilitation, and its trend along a drought gradient have...

Impatiens nimspurjae ( Impatiens , Balsaminaceae), a new species from Nepal is described based on molecular data and morphological characters. Notes on the diagnostic characters used to distinguish it from allied taxa are provided. I . nimspurjae is closely related with taxon belonging to sect.

Growing popularity of herbal medicine has increased the demand of medicinal orchids in the global markets leading to their overharvesting from natural habitats for illegal trade. To stop such illegal trade, the correct identification of orchid species from their traded products is a foremost requirement. Different species of medicinal orchids are t...

Habenaria is almost cosmopolitan in distribution having predominantly terrestrial orchids, however; a remarkable epiphytic species with some unique morphological characters was collected from Nepal. We conducted a molecular phylogeny of this unusual Habenaria species using nuclear (ITS) and chloroplast (matK, rbcl) DNA sequence regions to infer its...

Two new species of orchids from Nepal, Calanthe himalaicum and Habenaria palpensis are described and illustrated. Notes on the diagnostic characters used to distinguish them from allied taxa are provided. Present paper also summarizes various taxonomic publications on orchids of Nepal and reveals that the known orchid flora of Nepal comprises 502 t...

It is challenging to understand the drivers of plant-plant interaction patterns in dry mountains. However, such knowledge is important to assess alpine ecosystem resilience to climate change. In water-limited ecosystems, leaf δ13C and satellite-derived vegetation index (NDVI) may serve as reliable indicators of environmental severity to address pla...
