Nectar and nectary studies on seven Euphorbia species

open access: yes, 2004
The nectary morphology of six Hungarian and one grown Mediterranean leafy spurge (Euphorbia) species was studied and compared. Glands with various horns were found in E. amygdaloides L., E. cyparissias L., E. esula L., E. myrsinites L. and E.

Influence of floral visitation on nectar-sugar composition and nectary surface changes in Eucalyptus

open access: yes, 1997
Floral nectaries and their production of major nectar carbohydrates were studied in three species of Eucalyptus in Australia. In E cosmophylla, E grandis and E pulverulenta, the nectary is located on the inner surface of the hypanthium, below the stamen ...

The role of heterotopic shifts in floral nectary evolution of Anacardiaceae

open access: yes
The 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.

Complex but Coordinated Biochemistry Underlies Floral Nectary Function in Ornamental Tobacco [PDF]

open access: yes, 2007
The ornamental tobacco floral nectary gland is a remarkable organ that functions both to attract visiting pollinators and to protect the gynoecium from microorganisms vectored to the flower by these pollinators.
