“…Achene morphology is a diagnostic characteristic owing to the variation seen in specific and generic levels; therefore, achene morphology can make a distinction at the interspecific level (Szukala et al, 2019). Previous studies reported that achene micromorphology provides useful characteristics for the delimitation of different plant groups, and several achenes and pappus characteristics, achene shape, achene size, color, surface ornamentation, pappus color, length, and structure were suggested as useful in different taxonomic levels in the Asteraceae family (Bona, 2015; Candan et al, 2016; Özcan & Akıncı, 2019; Şirin et al, 2017). This study supports the utilization of achene micromorphology as a distinctive feature for the identification of species.…”

“…Macromorphological achene features of the studied species are traditionally used as diagnostic characteristics (Wagenitz, 1975). Several studies showed that achene micromorphology is also useful for identification and taxonomic delimitation in different genera in Asteraceae (Bona, 2014; Candan et al, 2016; Özbek et al, 2018; Rakizadeh, Attar, & Sotoodeh, 2019; Şirin, Ertuğrul, & Uysal, 2017). The present study aims to provide relevant characteristics of the achene macro‐micromorphology and the data useful for solving taxonomic problems through scanning electron microscopy (SEM) in the studied genera.…”

This study focuses on the macro-micromorphological achene characteristics of 12 species of the genera Crupina, Jurinea, and Klasea (Asteraceae) using light microscopy and the scanning electron microscopy (SEM). The morphological characteristics of the achenes, including shape, size, color, and surface pattern of achene, and hair structure, length, and color of pappus are studied. The results show that the achene length is between 3 and 8 mm, and its width is between 1 and 4 mm. Pappus is 4-15 mm long and persistent for seven species. SEM analysis shows four different achene surface patterns for the studied species: smooth, undulate, smooth-undulate, and undulate-ruminate. The genus Crupina has darkly colored achenes with yellow, dense firm hairs, and the achene surface pattern is smooth. Triangular and sulcate achenes seem to characteristic for the genus Jurinea. The genus Klasea distinguished from the remaining species studied with its straw-colored and deciduous pappus. Macro-micromorphological characteristics provide effective tools for both generic and intrageneric differentiation for the studied species. Research Highlights • In the genus Crupina, the achene is darkly colored with yellow, dense firm hairs, the pappus is red-purple above and yellow below, and the achene surface pattern is smooth. • The genus Jurinea can easily be separated from the remaining studied species with their triangular and sulcate achenes. • A straw-colored and deciduous pappus seems to be characteristic of the genus Klasea. • Achene macro-micromorphological characteristics provide useful tools that help the identification of the delimitation of the species.

“…Though previous studies support the use of achene surface patterns as diagnostic characters at species and subspecies levels for the genus Centaurea s.l., understanding the importance of these characters at generic and subgeneric levels requires further studies (Uysal et al, 2005;Çelik et al, 2005a, b;Aksoy et al, 2010;Okay and Demir, 2010;Shabestari et al, 2013;Bona, 2014;Candan et al, 2015). With this in mind, this study examines the exomorphic achene characters of 23 taxa belonging to the genera Centaurea, Cyanus, Psephellus and Rhaponticoides in Asteraceae by using light microscope (LM) and scanning electron microscope (SEM).…”

This study examines the exomorphic achene characteristics of 23 taxa belonging to Centaurea, Cyanus, Psephellus and Rhaponticoides in Asteraceae using light microscope and scanning electron microscope (SEM). The exomorphic characteristics studied are shape, size, colour and surface pattern of achene, and hair, length and colour of pappus. The results of the present investigation showed that achene size of the studied taxa is 3-7 × 1-4 mm. Pappus length is 1-14 mm, deciduous for three taxa and inner row is differentiated from the outer, 1-3 mm long, for 10 taxa. SEM studies showed eight different types of achene surface patterns for the studied taxa: Glebulate, glebulate-ruminate, reticulate, ribbed, ruminate, smooth, smooth-glebulate and undulate. Achene characteristics are useful for both intrageneric and intraspecific classification of the studied taxa.
