The present paper highlights a taxonomic account of genus Pteris L. (Pteridaceae E.D.M. Kirchn.) with newly reported species amoena Blume, which was collected from the Pange range Tale Wildlife Sanctuary and Hapoli Primary Forest, Hapoli, Lower Subansiri District Arunachal Pradesh. communication is based on plant exploration in-depth surveys done by first two authors through scrutiny herbaria l...

Abstract Species of Acanthaceae are predominantly associated with conserved forest environments such as Iguaçu National Park (PARNA Iguaçu), which is composed Semideciduous Seasonal Forest and Araucaria forest. The aim this work was to perform a floristic study PARNA Iguaçu, botanical illustrations, an identification key descriptions the species. Collections were carried out monthly from August...

A thorough research on the scientific activity of Guglielmo Gasparrini, Giovanni Gussone and Augustin Pyramus De Candolle allowed authors to adress a in several European herbaria looking for type name Senecio pygmaeus DC. The original specimen sent by mentioned protologue is still kept at G-DC designated as lectotype, whilst three other herbarium sheets, preserved NAP-GUSS, PAL PAV respectively...

Knowing the geographical origin of economically important plants is important for genetic improvement and conservation, but has been slowed by uneven geographical sampling where relatives occur in remote areas of difficult access. Less biased species sampling can be achieved when herbarium collections are included as DNA sources. Here, we address the history of Cucurbitaceae, one of the most ec...

Maximum entropy (Maxent) modeling was used to predict the potential climatic niches of three medicinally important Asclepiad species: Pentatropis spiralis, Tylophora hirsuta, and Vincetoxicum arnottianum. All three species are members of the Asclepiad plant family, yet they differ in ecological requirements, biogeographic importance, and conservation value. Occurrence data were collected from h...
