Comparative Nectary Morphology across Cleomaceae (Brassicales)

open access: yesPlants, 2023
Floral nectaries have evolved multiple times and rapidly diversified with the adaptive radiation of animal pollinators. As such, floral nectaries exhibit extraordinary variation in location, size, shape, and secretory mechanism. Despite the intricate ties to pollinator interactions, floral nectaries are often overlooked in morphological and ...

Nomenclatural revision of Pinguicula (Lentibulariaceae) in the Baltic and Nordic countries including their oversea territories and Iceland

open access: yesNordic 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

open access: yesNordic 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)
