Floral Nectaries in Leguminosae: Structure, Diversity, and Possible Evolution
The Botanical ReviewFloral nectar is a key reward in Leguminosae despite the exceptional diversity of flowers in this family. The paper aims to summarize the available data on structure, ontogeny, regulation, and possible evolution of the leguminous floral nectaries. To date, detailed characterization of ultrastructure and mode of secretion is available only for a few ...

Where is the reward? Floral nectaries in Aspidosperma australe flowers
Rodriguésia, 2020 Abstract Nectaries are secretory structures that produce a solution rich in sugars, which are involved in animal-plant interactions. Such secretory structures can be externally distinguishable (recognizable), as in glands or discs, or not, as in some gynoecial ones.

The role of heterotopic shifts in floral nectary evolution of Anacardiaceae
Perspectives in Plant Ecology, Evolution and SystematicsThe flowers of Anacardiaceae are known to produce nectar, in most cases secreted by a nectary disk, which may have an intra- or more rarely extrastaminal position. Exceptions include species that produce nectar via secretory trichomes on the petals and/or base of the stamens.

Shining a light on UV-fluorescent floral nectar after 50 years
Scientific ReportsNature is aglow with numerous captivating examples of UV-fluorescence in the animal kingdom. Despite a putative role as a visual signal, exploration of UV-fluorescence in plants and its role in plant-animal interactions is lagging in comparison.

Unravelling the Homology between Calycine Glands in Malpighiales: New Data from Basal Malpighiaceae
PlantsDiscussing homology relationships among secretory structures remains a relatively underexplored area in botanical research. These structures are widely dispersed within Malpighiales, one of the largest orders of eudicots.

Starch function in ornamental tobacco floral nectary development
, 2018 Morphological changes of floral nectary gland and subcellular transition of floral nectary cells of ornamental tobacco LxS8 were exclusively investigated in this study. Enlargement of the floral nectary gland of ornamental tobacco LxS8 that occurs during development is accompanied by a major accumulation of Periodic Acid-Schiff's staining (PAS-staining)

Ants visiting inflorescences of Actinocephalus polyanthus (Bong.) Sano (Eriocaulaceae)
Biotemas, 2013 Plants from the family Eriocaulaceae have a secretion of nectar in floral structures which promotes insect visitation, including ants. This study evaluated the ant species visiting inflorescences of Actinocephalus polyanthus in coastal dunes in southern ...
