THE EXTRAFLORAL NECTARIES OF IPOMOEA CARNEA (CONVOLVULACEAE)
American Journal of Botany, 1977 Ipomoea carnea (Convolvulaceae) possesses two types of extrafloral nectaries, located on the petiole and on the pedicel. These secrete a complex nectar containing sugars and amino acids. The insects attracted to the extrafloral nectaries are predominantly ants and they are relatively abundant throughout the year.

Frontiers in Plant ScienceExtrafloral nectaries (EFNs) are nectar-secreting glands on vegetative organs that mediate indirect plant defense by recruiting predatory arthropods. Documented in over 4,999 species across 129 families, with at least 457 independent evolutionary origins,

Nectary Structure and Nectar Secretion Characteristics Among Various Cultivars of Paeonia lactiflora
PlantsBackground: Paeonia lactiflora Pall. produces substantial quantities of nectar during the bud stage. In the production of cut flowers, this nectar attracts contaminants that compromise the quality of the flowers.

Biology of extrafloral nectaries in Albizzia lebbeck (Mimosaceae)
South African Journal of Botany, 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 oxalate of reversible nature and sclereids were observed in the nectaries.

Distribution of Plants with Extrafloral Nectaries in Temperate Communities
American Midland Naturalist, 1980 The abundance of plants with extrafloral nectaries was determined for a series of temperate habitats in Nebraska. Mean cover of plants with extrafloral nectaries was 1.3% in riparian forest understory, 1.8% in virgin deciduous forest understory, 0.0% in tall-grass prairie, and 8.3% in sandhill prairie.

Pesquisa Agropecuária Brasileira, 2001 Extrafloral nectaries (EFNs) are structurally variable and widely spread among the angiosperms. The occurrence of EFNs in leaves of Pterodon polygalaeflorus Benth. and Pterodon pubescens Benth. (Fabaceae: Papilionoideae) were detected in adult specimens,

Plants with Extrafloral Nectaries and Ants in Everglades Habitats
The Florida Entomologist, 1992 The terrestrial vegetation of the inland areas of the Everglades is of three main types, occurring on oolite limestone substrate of progressively higher elevation: sawgrass prairie, or glade; pineland; and hardwood hammock. Nectar-drinking ant abundance was assessed using transects of honey baits, and is highest in pineland, and lowest in glade habitat.

Structure of the extrafloral nectaries of Vicia (L.) Fabaceae
Acta Agrobotanica, 2013 Extrafloral nectaries on the abaxial surface of stipules were investigated in the <i>Vicia angustifolia, Vicia sativa, Vicia sepium</i> and <i>Vicia grandiflora</i>. In V. <i>angustifolia</i> nectaries were also located on the calyx surface.
