Evolution of floral nectary in Lamiaceae
Proceedings / Indian Academy of Sciences, 1986The morphology and vasculature of the floral disc have been studied in 30 species of Lamiaceae to discuss its phylogeny. In Lamiaceae the disc receives vascular supply mostly from the gynoecial bundles which indicates its association with the gynoecium.

Morphological and ultrastructural studies of floral nectaries in Rhamnaceae
The Journal of the Torrey Botanical Society, 2016Morphology, anatomy, and ultrastructure of nectaries of 12 species belonging to five tribes of Rhamnaceae (Pomaderreae, Colletieae, Paliureae, and Gouanieae of the Ziziphoids clade and Rhamneae of the Rhamnoids clade) were studied by light and electron microscopy. Four types of nectaries were observed in this study.

Protoplasma, 2011
The Polemoniaceae family forms flowers diverse in the terms of pollination methods and nectar types. The micromorphology of the nectary surface and the tissue structures as well as the ultrastructure of the cells of the floral nectaries in Polemonium caeruleum L. were examined using light, scanning and transmission electron microscopy.

A systematic survey of floral nectaries
2007The construction of classifications, as well as the understanding of biological diversity, depends upon a careful comparison of attributes of the organisms studied (Stuessy, 1990). It is widely known that data from diverse sources showing differences from taxon to taxon are of systematic significance.

A New Tribal Classification of Mesembryanthemaceae: Evidence from Floral Nectaries
Taxon, 2002Abstract Mesembryanthemaceae Fenzl, here defined as excluding Aizoaceae Rudolphi s.str., are divided into five major groups, primarily on the basis of characters of the floral nectary. In terms of nectary type, the meronectary is considered a synapomorphy for the family Mesembryanthemaceae.

MORPHOLOGY AND ANATOMY OF FLORAL AND EXTRAFLORAL NECTARIES IN CAMPSIS (BIGNONIACEAE)
American Journal of Botany, 1976The genus Campsis (Bignoniaceae), with one New World and one Old World species, is unusual among temperate plants in having five distinct nectary sites. Multiple nectaries occur at all four of the extrafloral sites (petiole, calyx, corolla, fruit), representing an advanced strategy for ant attraction.

Protoplasma
Floral nectaries are generally linked to an exchange that facilitates pollen transport, and consequently, pollination. We have characterized the ontogenesis, histochemistry, and ultrastructure of the floral nectary of Pseudobombax longiflorum (Mart.) A.

Anatomy of the floral nectaries of some neotropical Salacioideae (Celastraceae)
Plant Systematics and Evolution, 2012Floral nectaries have contributed to the systematics of different taxonomic groups. Since those of the neotropical genera included in subfamily Salacioideae—Cheiloclinium Miers, Peritassa Miers, Salacia L. and Tontelea Aubl.—have different forms and positions, we explored their anatomy to delimit more precisely the genera of subfamily Salacioideae ...
