“…In colleters of Roupelia the process of senescence is initiated at the apex and proceeds basipetally. This is in accordance with the observations made in the resin glands of Passiflora by Durke et al (1984).…”

1989. Anatomy and histochemistry of colleters in Roupelia grata (Apocynaceae). -Nord. J. Bot. 8: 493496. Copenhagen. ISSN 0107-055X. The colleters of Roupelia grata are present on the petiole of the leaf, bract, bracteole and calyx. A mature colleter has a distinct head and a stalk. The parenchymatous central core is surrounded by epithelial cells. The senescence of the colleter occurs at its apex first and then proceeds towards the base.

“…The association between crystals and extrafloral nectaries in Pithecellobium have be.m emphasized by Dave & Menon (1987). Durke et al (1984) also report the occurrence of crystal druses in the resin glands of Passiflora foetida. Unlike Aganosoma (Dave et al 1987), no hairs are found on the colleters in Roupelia.…”

“…For example, the EFNs of Citharexylum mirianthum (Verbenaceae) produce lipids (S.R. Machado, unpublished results) and those of Passiflora foetida (Passifloraceae) also secrete lipids rather than sugars; so they are not 'nectaries' sensu stricto (Roth 1968;Durkee et al 1984).…”

Morphological patterns of extrafloral nectaries in woody plant species of the Braziliancerrado

et al. 2008

Extrafloral nectaries are nectar-secreting structures that are especially common among the woody flora of the Brazilian cerrado, a savanna-like vegetation. In this study, we provide morphological and anatomical descriptions of extrafloral nectaries (EFNs) occurring on vegetative and reproductive organs of several plant species from the cerrado, and discuss their function and ecological relevance. We describe the morphology and anatomy of EFNs of 40 species belonging to 15 woody families using scanning electron microscopy and light microscopy. We categorise EFNs following a structural-topographical classification, and characterise the vascularised and complex nectaries, amorphous nectaries and secretory trichomes. Fabaceae, Bignoniaceae, Malpighiaceae and Vochysiaceae were the plant families with the majority of species having EFNs. Ten species possess more than one morphotype of gland structure. Observations and experimental field studies in the cerrado support the anti-herbivore role of EFN-gathering ants in this habitat. Additional morphological studies of EFNs-bearing plants, including other growth forms (e.g. herbs and lianas), are being undertaken and will hopefully cast further light on the ecological relevance of these glands in the cerrado, especially with respect to their attractiveness to multiple visitors.

Ultrastructure and histochemistry of secretory ducts in Artemisia campestris ssp. maritima (Compositae)

The histochemical characterization of the oleoresin produced by secretory ducts of Artemkiu campestris ssp. maritima revealed the presence of terpenoids (essential oils, resiniferous acids and probably steroids), alkaloids and fatty acids, eventually polyacetylenes. The ultrastructural study of A. campestris ducts enabled us to consider that the secretory activity begins very early during the duct development. The oleoresin deposited in the duct cavity is produced by epithelial and sub‐epithelial cells that contain, at the secretory phase, a great amount of smooth endoplasmic reticulum (SER) surrounding plastids with few thylakoids. These organelles may play an important role in the oleoresin production, the SER probably being responsible for some steps in the biosynthesis of oleoresin components and for the transport of the secreted material towards the plasmalemma. Endoplasmic reticulum and mitochondria probably have a role in the synthesis of steroids. After secretion, the duct glandular cells degenerate progressively. The extrusion process of secretion may be considered mero‐holocrine.
