Morphology and Distribution of Petiolar Nectaries in \u3ci\u3eIpomoea\u3c/i\u3e (Convolvulaceae) [PDF]
, 1979 The distribution of petiolar nectaries in 24 species of Ipomoea was investigated. Petiolar nectaries were found on 12 species (8 new reports, 4 confirmations of previous reports) and quoted from the literature as being found on 3 other species; they were

The Octadecanoid Pathway, but Not COI1, Is Required for Nectar Secretion in Arabidopsis thaliana
Frontiers in Plant Science, 2018 Over 75% of crop species produce nectar and are dependent on pollinators to achieve maximum seed set, yet little is known about the mechanisms regulating nectar secretion.

Entomological Science, Volume 29, Issue 3, September 2026.Three sibling parasitoid wasps of the Cotesia inducta (Braconidae) complex attack ant‐associated lycaenid larvae in Japan. Species differ in host range, seasonal host use and feeding habitat. Differences in host‐feeding habitat may contribute to diversification within the Cotesia inducta complex. Abstract Approximately 75% of lycaenid butterfly species

American Journal of Botany, Volume 113, Issue 8, August 2026.Abstract Premise The identity of sterile floral organs in second‐whorl, alternisepalous positions within Caryophyllaceae remains contentious, having been described as staminodes, “petaloids,” or petals homologous with those of other Pentapetalae. Limited ingroup and outgroup sampling and floral developmental data and inadequate phylogenetic comparative

Mutualism and Antagonism in a Post‐Extinction Hawaiian Bird–Lobelioid Pollination System
Ecology and Evolution, Volume 16, Issue 8, August 2026.Species loss can restructure plant–pollinator interactions, but the functional consequences of altered interactions remain unclear. Using camera observations and experimental manipulations in Hawaiian lobelioids, we show that nectarivorous birds differ in whether visits result in pollen contact or nectar robbing, with robbing altering nectar dynamics ...

New Perspectives on the Biology of Nectaries and Nectars [PDF]
, 2019 Nectar is one of the key developments in the evolution of plant-animal mutualisms. Floral nectar (FN) attracts pollinators, whereas extrafloral nectar (EFN) recruits insects that defend plants against herbivory.

MORPHOLOGY OF THE NECTARY IN PROTEACEAE [PDF]
New Phytologist, 1967 SummaryA comprehensive study of the comparative morphology, anatomy and histology of the nectary in all genera of the Proteaceae was made and the trends in its evolution are discussed. The nectaries in some abnormal flowers of Hakea laurina and Buckinghamia celsissima are also described.

Biology of extrafloral nectaries in Albizzia lebbeck (Mimosaceae) [PDF]
, 1991 The structure and ecology of extrafloral nectaries in Albizzia lebbeck Benth. were studied. Two flat non-porate nectaries are present on the adaxial surface of each rachis. The sub-secretory zone is parenchymatous and contains starch. Crystals of calcium
