Extrafloral nectaries in Combretaceae: morphology, anatomy and taxonomic significance

  title={Extrafloral nectaries in Combretaceae: morphology, anatomy and taxonomic significance},
  author={Patricia M. Tilney and Abraham E. van Wyk},
Extrafloral nectaries (EFNs) in members of the Combretaceae are nectaries not involved with pollination and occurring on vegetative structures; they are believed to attract ants to protect plants against herbivorv by other insects. In the Combretaceae EFNs are reported in species of Terminalia L. and Pteleopsis Engl., putative EFNs in Meiostemon Exell & Stace and Quisqualis L., and an absence of EFNs in Combretum Loefl. and Lumnitzera Willd. EFNs in the family are generally spherical in shape…

Generic status of Quisqualis (Combretaceae), with notes on the taxonomy and distribution of Q. parviflora
It is suggested that different pollination strategies have developed independently in the Combretum–Quisqualis clade, resulting in convergent morphological trends in floral morphology.
Insights on the systematics and morphology of Humiriaceae (Malpighiales): androecial and extrafloral nectary variation, two new combinations, and a new Sacoglottis from Guyana
The diversity of stamen structures in the family with consideration of dehiscence patterns and the evolutionary transitions between tetra- and disporangiate anthers is surveyed, and the significance of inter-generic variation in gland position and anther morphology within the family is discussed.
Morphological and anatomical traits during development: Highlighting extrafloral nectaries in Passiflora organensis.
Passiflora organensis is a small herbaceous vine with characteristic morphological variations throughout its development. The plant bears button-shaped extrafloral nectaries exclusively in adult
The use of extrafloral nectar in pest management: overcoming context dependence
Summary Extrafloral nectar (EFN) provides plants with indirect defence against herbivores by attracting predatory insects, predominantly ants. Decades of research have supported the role of EFN as
Leaf teeth in eudicots: what can anatomy elucidate?
For each family studied, there was only one type of association between gland and tooth, demonstrating the systematic potential of these glands in eudicots.
Phylogenetic relationships of Combretaceae inferred from nuclear and plastid DNA sequence data: implications for generic classification
Relationships between genera of Combretaceae by means of combined analyses of plastid and nuclear sequences are explored and sectional classification within Combretum proposed in earlier morphological studies is confirmed except for the exclusion of C. imberbe.
Blind estuaries during drought: The influences of a sandbar on mangrove trees
Small blind estuaries are a common phenomenon on the coast of Nicaragua, but unfortunately not much is known on their hydrological characteristics. A blind estuary can be identified by a sandbar that


Extrafloral nectaries that attract ants in Bromeliaceae: structure and nectar composition
The occurrence of extrafloral nectaries in some species of Bromeliaceae (subfam. Pitcairnioideae) is reported for the first time in the following plants from central and northern Argentina:
Nectaries and reproductive biology of Croton sarcopetalus (Euphorbiaceae)
Flower morphology, nectary structure, nectar chemical composition, breeding system, floral visitors and pollination were analysed in Croton sarcopetalus, a diclinous-monoecious shrub from Argentina, indicating that fruit production in this species is not pollen/pollinator limited and is mediated by a wide array of pollinators.
Extrafloral nectaries: their taxonomic distribution and abundance in the woody flora of cerrado vegetation in southeast Brazil
The taxonomic distribution and abundance of woody plants with extrafloral nectaries (EFNs) are reported for different areas of cerrado vegetation (subtropical savanna) in the state of Sao Paulo,
A contribution to the leaf and young stem anatomy of the Combretaceae
A comprehensive survey of anatomical features of the leaf and young stem in southern African Combretaceae has been conducted, finding some of the structural characters are of systematic significance and useful for generic and sectional recognition as well as the identification of sterile material.
Importance des nectaires extra—floraux dans les interactions plantes-fourmis
Summary Morphological, histological and functional features about extra- floral nectaries are studied. In ant—plant interactions, in protection against herbivores, they involve a more or less great
Extra-nuptial nectar glands, by their secretion, attracts to the plants which bear them, hordes of ants which constitute a temporary and changing bodyguard, disputing the presence of all other insects with the exception of their proteges the sugar-secreting aphids, coccids, etc, and resisting often furiously and effectively, the onslaught of ruminants and other large animals.
Extrafloral nectaries in the genus Macaranga (Euphorbiaceae) in Malaysia: comparative studies of their possible significance as predispositions for myrmecophytism
Possession of extrafloral nectaries does not appear to be essential for the development of symbiotic ant-plant interactions, and a comparison with other euphorb species living in the same habitats as Macaranga showed that in genera in which extrafloras are widespread, no myrmecophytes have evolved.
Observations of flowering confirmed the reported short duration of the individual flowers and the nectar from foliar nectaries contained equal concentrations of glucose, fructose, and sucrose.
Secretory structures on the leaf rachis of Caesalpinieae and Mimosoideae (Leguminosae): implications for the evolution of nectary glands.
The occurrence of rachis glands in seven of the ten species of the Paleotropical genus Erythrophleum, a member of the Dimorphandra group of caesalpinioids thought to include the sister group(s) of mimosoids, and of the patches of trichomes are primitive homologues of more organized glands are discussed.
The extrafloral nectaries of cowpea (Vigna unguiculata (L.) Walp.) II. Nectar composition, origin of nectar solutes, and nectary functioning
Nectar was collected from the extrafloral nectaries of leaf stipels and inflorescence stalks, and phloem sap from cryopunctured fruits of cowpea plants, and nectar invertase functioned optimally (phloem-sap sucrose as substrate) at pH 5.5, with a starting sucrose concentration of 15% (w/v).
