“…Rahiminejad et al [38] found that, among micromorphological characters of Centaurea species, the type and density of epidermal indumentum of leaf and stem were of particular taxonomic value. We recorded two types of non-glandular trichomes on C. sadleriana, including those with thick-walled and thin-walled basal cells, which were more numerous on the abaxial epidermis.…”

The lamina, main vein and peduncle anatomical properties of Centaurea sadleriana Janka plants from two populations, were examined using light and scanning electron microscopy. The indumentum was comprised of glandular and non-glandular trichomes of two types. The leaves were amphistomatic, isolateral, with strongly developed palisade tissue. Secretory ducts were observed along the phloem or sclerenchyma of large vascular bundles. Collenchyma alternated with chlorenchyma in the main vein and peduncle. Large groups of strongly lignified sclerenchyma were present along the phloem of peduncle vascular bundles. These features, together with thickened walls of epidermal cells and cuticle, numerous trichomes and thick-walled parenchyma in the perimedullar zone, were perceived as a xeromorphic peduncle structural adaptation. Non-enzymatic antioxidant compounds of phenolic origin were detected in small amounts and their respective content was higher in leaves compared to inflorescences. Compounds of phenolic orgin showed positive correlation with total potenial of antioxidant activity indicated by the DPPH assay. Greater total quantity of polyphenols and tannins was detected in leaves of plants from Zobnatica locality, while leaves of plants from Rimski Sanac were characterized by higher content of total flavonoids and proantocyanidins. Phytochemical analysis showed that dominant secondary biomolecules in inflorescences were phenolic pigments including anthocyanins and leucoanthocyanins, and free quinones in leaves.

“…However, it should be pointed out that characters of the involucre and the involucral bracts are the most important ones in sect. Acrocentron and, in many cases, they are the only useful ones for separating closely related species (Font et al 2002, 2009, Rahiminejad et al 2010, Ferrer-Gallego et al 2017).…”

A new species of Centaurea sect. Acrocentron (Cass.) DC. (Asteraceae) found growing in dry, steppe‐like habitats on the Zlatibor mountain in western Serbia is described as Centaurea zlatiborensis. This novelity is compared with all other species of C. sect. Acrocentron known from Serbia and a diagnistic key to these is provided. Centaurea zlatiborensis is morphologically close to C. calocephala Willd. but the stems are simple or sparsely branched with monocephalous branches and itis generally smaller in all plant parts. The most important difference is the appendage morphology where C. zlatiborenis has triangular, dark brown appendages with short fimbriae and appendages not completely covering the bracts.

“…Dobrocz.] integra unas 100 especies con distribución principalmente mediterránea, aunque algunas de ellas se extienden por gran parte de la región eurosiberiana (Font et al, 2002(Font et al, , 2009Font, 2007;Rahiminejad et al, 2010), estando asimismo representado por un elevado número de endemismos (Gardou, 1975;Wagenitz, 1975). Esta sección incluye especies perennes, acaules o caulescentes, con tallos no alados, brácteas involucrales medias con apéndice triangular y decurrente, pectinado-fimbriado o más comúnmente pectinado-espinoso.…”

Centaurea inexpugnabilis, a new species from section aCroCentron for the iberian flora.-A new species for the genus Centaurea L. (sect. Acrocentron, Asteraceae) is described: C. inexpugnabilis, sp. nov. This plant has been found in the Mallos de Riglos (Riglos, Huesca, Spain), and its distribution is currently limited to the northeastern of the Iberian Peninsula. A description and diagnosis, iconography and several tables showing the main diagnostic characters to differentiate it from its related species is reported. Key words: Asteraceae; Centaurea; new species; sect. Acrocentron; Spain; taxonomy. ResumenCentaurea inexpugnabilis, una nueva especie de la sección aCroCentron para la flora ibérica.-Se describe una nueva especie para el género Centaurea L. (sect.
