A new species of Impatiens (Balsaminaceae), I. lohitensis R. Gogoi & S. Borah is described and illustrated from Arunachal Pradesh, India. It close to siculifer Hook.f. stenantha but differs in perennial nature, bigger elliptic leaves, green flower bud without awn, sized flower, floral bract, lateral sepals navicular, abaxial midvein upper petal thickened, much longer spur, two red blotch at throat size linear capsule.
Abstract Herbarium collections shape our understanding of the world’s flora and are crucial for addressing global change biodiversity conservation. The formation such natural history collections, however, not free from sociopolitical issues immediate relevance. Despite increasing efforts representation colonialism in herbaria have received comparatively less attention. While it has been noted that majority plant specimens housed North, extent this disparity rigorously quantified to date....
The main aim of this study is to produce a modern analog for pollen and non-pollen palynomorphs (NPPs) preserved in soil relation the different vegetation types herbivore impact Kaziranga National Park (KNP). data obtained reflects both extant each habitat as well landuse, but some site-by-site variation was observed with respect coprophilous fungal spores present palynoassemblage. Canonical correspondence analysis (CCA) reveals presence five significantly types, while are relatively similar...
A new species Impatiens paramjitiana is described and illustrated from Siang valley of Arunachal Pradesh, India.
