Where is the reward? Floral nectaries in Aspidosperma australe flowers [PDF]

open access: yesRodriguésia
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 ...

Nectar biosynthesis is conserved among floral and extrafloral nectaries [PDF]

open access: yes, 2021
Nectar is a primary reward mediating plant-animal mutualisms to improve plant fitness and reproductive success. Four distinct trichomatic nectaries develop in cotton (Gossypium hirsutum), one floral and three extrafloral, and the nectars they secrete ...

Foliar, nonstructural nectaries in the Marantaceae [PDF]

open access: yes, 1985
Nonstructural, foliar nectaries have been found in two genera of the Marantaceae (Zingiberales). Two nectaries are located on each leaf, at the junction of the leaf sheath and petiole.
