A taxonomic revision of Centaurea sect. Microlophus (Asteraceae, Cardueae–Centaureinae) and three new records for the flora of Iran

Abstract

A global taxonomic revision, lectotypifications and neotypifications of Centaurea L. sect. Microlophus (Cass.) DC. (Asteraceae) are presented. The recognized species, the relevant synonyms, type details, examined specimen lists, full descriptions and a taxonomic key are provided for this section. The geographic distribution of all the 9 species recognized is mapped. Centaurea alveicola Rech. f., C. rigida Banks & Sol. and C. polypodiifolia Boiss. var. szovitsiana (Boiss.) Wagenitz are reported as new to the flora of Iran.

1010. KLASEA CERINTHIFOLIA: Compositae

“…Whilst there is little doubt what defines K. cerinthifolia , there is a significant nomenclatural issue intertwined with the history of Centaurea behen , a sympatric species with considerable overlap in its distribution in a substantial part of their range, including Turkey, Iran, Iraq (e.g. see distribution maps in Davis & Kupicha, 1975; Martins, 2006; Negaresh & Rahiminejad, 2015; and the account by Arènes, 1947), and especially Syria, around the city of Aleppo.…”

“…Negaresh & Rahiminejad, with a simplistic ‘Nomenclatural note’ (Nagaresh & Rahiminejad, 2015: 341), merely stated the type locality phrase and that ‘no type specimen was indicated’, but failing to comment on the original material in Linnaeus's protologue. They designated a neotype, ‘Turkey, Anon.…”

“…s.n. (LINN‐HS‐138‐36)’ (Nagaresh & Rahiminejad, 2015: 340, Fig. 4); this is an ineffective neotypification – a neotype cannot be designated since original material existed (Turland et al ., 2018: Code Art.…”

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

“…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 , ).…”
