A contribution to the taxonomy of Centaurea sect. Cynaroides (Asteraceae, Cardueae–Centaureinae) in Iran

Abstract

The taxonomy of Centaurea sect. Cynaroides is revised in Iran. A new species Centaurea karamianiae closely related to C. regia and C. amadanensis is described from Kermanshah Province, W Iran. In addition, C.gabrieliae and C. wendelboi are transferred from C. sect. Cynaroides to the new section C. sect. Ranjbarianae.

Centaurea bingoelensis (Asteraceae), a new species from Turkey

“…The sectional classification of Centaurea is mainly based on morphology of the appendages of phyllaries, the achenes, and the pappus (Negaresh and Rahiminejad, 2014 (Wagenitz 1975(Wagenitz , 1980Negaresh and Rahiminejad 2014). This new species is included in the section Cynaroides.…”

Centaurea rahiminejadii sp. nov. and a new record in the genus Centaurea (Asteraceae, Cardueae–Centaureinae) from Iran

“…Cynaroides Boiss. ex Walp., which includes taxa that often have racemose or dichasial synflorescences, decurrent upper cauline leaves, ovoid to subglobose involucres, triangular to ovate or orbicular appendages that are non‐decurrent, usually ciliate and ending in a firm spine or spinule, and rose, purple or yellow flowers (Negaresh et al , Negaresh and Rahiminejad ). Based on the literature, the herbarium specimens studied and our field observations, it can be concluded that most of the taxa belonging to Centaurea sect.…”

“…al. 2013a), Centaurea alfonsoi (Negaresh et al ), Centaurea karamianiae (Negaresh and Rahiminejad ), and Fibigia kermanshahensis (Ranjbar et al ). The flowers of C. rahiminejadii are pollinated by some Scarabaeidae (Fig.…”

“…and Rhaponticoides Vaill. Shortly before and following these new treatments, Centaurea s.s., underwent many changes and was considerably expanded by the description of new taxa (Wagenitz and Esfandiari , Akhani , Ranjbar et al , , , Ranjbar and Negaresh , , , , , , , Negaresh et al , , Negaresh and Rahiminejad , ).…”
