Flowering, nectar secretion, and structure of the nectary in the flowers of Acer pseudoplatanus L.
Acta Agrobotanica, 2019 Flowering and nectar release in Acer pseudoplatanus were investigated between 2011 and 2013. The micromorphology of the floral and nectary elements was observed using a scanning electron microscope and the anatomy of nectaries was examined by light ...

Nordic Journal of Botany, EarlyView.Names in the genus Pinguicula established for taxa from the Baltic and Nordic countries, including their oversea territories and Iceland, were analyzed to provide nomenclatural and taxonomic clarity. Of the 33 names retrieved from the literature and online databases, one is illegitimate, two are invalid and 16 were found to require typification.

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India
Nordic Journal of Botany, EarlyView.A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)
