Extrafloral Nectaries in Solanum
Biotropica, 1985Extrafloral nectaries (EFNs) occur on the corollas of 3 dioecious species of Solanum (S. cunninghamii Benth., S. dioicum W.V. Fitzg., and S. tudununggae Symon) from Australia. Solanum dioicum also bears EFNs on the leaves. This is the first report of nectaries of any kind for the genus Solanum, the first report of EFNs for the family Solanaceae, and ...

The Influence of Extrafloral Nectaries on Parasitism of an Insect Herbivore
American Journal of Botany, 1996The extrafloral nectaries of many plants promote ant defense against insect herbivores. We examined the influence of extrafloral nectaries on the levels of parasitism of a generalist insect herbivore, the gypsy moth (Lymantria dispar L.). Larvae and pupae of the moth were collected from trees with and without extrafloral nectaries growing in the same ...

Extrafloral Nectaries in Acacia mangium
Tropical Plant Biology, 2012Our microscopy studies describe the anatomy of extrafloral nectaries on the abaxial side of the basal part of every leaf stalks of Acacia mangium. The lens-like nectary expands with the development of the leafstalk, peaks at the stage at which the leafstalk itself has reached its mature size.

Extrafloral Nectaries of Some Australian Bipinnate Acacias
Australian Journal of Botany, 1985The extrafloral nectaries of some Australian bipinnate Acacia species are examined, coming from three sections: Acacia (two species); Botrycephalae (27 species); and Pulchellae (12 species). The nectaries are of the same three types as are found in phyllodineous species, i.e.

Structure and biology of extrafloral nectary inDesmanthus varigatus
Feddes Repertorium, 1992AbstractThe structure of the extrafloral nectaries in Desmanthus varigatus was studied at the level of light microscope. A shallow cup shaped, non‐porate nectary present at the rachis base and had developed from a group of initials of hypodermal origin. The mature nectaries were supplied by phloem and had non‐glandular, cuticularized trichomes at their

Extrafloral Nectaries of Some Australian Phyllodineous Acacias
Australian Journal of Botany, 1981The extrafloral nectaries of 43 phyllodineous Acacia species in the sections Phyllodineae, Plurinerves and Juliflorae were examined; material was collected mainly in south-eastern Queensland. The nectaries were of three types: porate (30 species), non-porate (12 species) and flat (only Acacia macradenia).

Distribution and morphology of extrafloral nectaries in some Cucurbitaceae
Botanical Journal of the Linnean Society, 1984A study of extrafloral nectaries has been made in the Cucurbitaceae to ascertain their structure and assess their taxonomic potential. Nineteen species representing nine Old World genera and one New World genus were examined. These included Telfairia occidentalis, Telfairia pedata, Momordica charantia, Lagenaria siceraria, Citrullus lanatus, Luffa ...

EXTRAFLORAL NECTARIES IN EBENACEAE: ANATOMY, MORPHOLOGY, AND DISTRIBUTION
American Journal of Botany, 1984Previous superficial reports, but only one anatomical study of one species, have supported the view that extrafloral nectaries (EFNs) of the unusual Benincasa type (i.e., with several layers of small nectariferous cells) of “Flachnektarien” (surface nectary) are common in Ebenaceae.

THE FUNCTION OF EXTRAFLORAL NECTARIES IN OPUNTIA ACANTHOCARPA (CACTACEAE)
American Journal of Botany, 1979Opuntia acanthocarpa (Cactaceae) possesses extrafloral nectaries embedded in the areoles of new reproductive and vegetative growth. The nectar secreted by these glands attracts ants and is a nutritional food source. Members of one attracted ant species, Crematogaster opuntiae (Myrmicinae), are aggressive and efficient defenders of the plants against ...
