“…Also, the significance and usefulness of SEM in solving taxonomic problems and in describing taxa have been emphasized by many researchers (Eroğlu et al, 2022; Heywood, 1971; Karaismailoğlu & Erol, 2018). However, there are few studies on the importance of achene micromorphology in the genus Artemisia (Abdel‐Hamid, 2020; Al‐Ajmi et al, 2021; Boyko, 2013; Vakulenko et al, 2020). In this study, Turkish Artemisia taxa have been examined for the first time.…”

“…The Artemisia L. is one of the largest genera in the tribe Anthemideae Cass. of the family Asteraceae Dumort., comprises 550 species distributed in the Northern Hemisphere (Beer, 2005; Boyko, 2010; Vakulenko et al, 2020) with aromatic plant, subshrubs, or shrubs (Al‐Ajmi et al, 2021). Taxa of the genus Artemisia are usually utilized in folk and modern medicine for curing illnesses like malaria, hepatitis, cancer, and infections induced by fungi, bacteria, and viruses (Abad et al, 2012; Al‐Ajmi et al, 2021; Karaismailoğlu, 2014; Willcox, 2009).…”

“…Some morphological, anatomical, cytological, and palynological studies on some taxa of the genus Artemisia have been made, so far ( Kursat et al, 2014; Kursat et al, 2015; Kursat et al, 2018; Kursat, Civelek, et al, 2011; Kursat, Turkoglu, et al, 2011; Nourbakhsh et al, 2008; Pınar & Adıgüzel, 1998; Sancar et al, 2021; Tabur et al, 2012; Tabur et al, 2014). Also, morphological characters of the achenes have been taken into account for the diagnosis of a small number of Artemisia taxa in different countries (Abdel‐Hamid, 2020; Al‐Ajmi et al, 2021; Boyko, 2013; Vakulenko et al, 2020). However, the significance of the achene in the genus has often been ignored in Turkey, where is one of the centers of diversity for the genus.…”

“…Scanning electron microscopy (SEM) is very significant for carpological micromorphology. It permits to examine the ultrastructure of integuments in more data and to clarify extra fruit characters, such as the features of the carpopodium and the apical bowl, primary and secondary surface structures ultrastructure of the surface (Boyko, 2010;Mukherjee & Nordenstam, 2010;Ullah et al, 2019;Vakulenko et al, 2020). SEM with energy dispersive x-ray spectrometry (SEM-EDS) is an elemental microanalysis technique broadly practical across a wide range of the physical and biological sciences, technology, and forensic studies (Goldstein et al, 2003).…”

In the study, the achene macromorphological and micromorphological characters of the genus Artemisia distributed in Turkey have been researched with the target of knowing systematically important carpological structures for the examined species. Macro‐morphological structures of the achenes including color, shape, dimension, and carpopodium diameter were studied with 100 achenes of 10 specimens per taxa with a Light Microscope. Micro‐morphological features of the achenes containing surface ornamentation, anticlinal and periclinal cell walls, epidermal cells, and the presence of secondary structures were examined with a Scanning Electron Microscope. EDS analyses were performed with a SEM. EDS analyses were carried out by selecting the same spot on the sample surface at 80 sec under 30 μm aperture size, with 20 kV acceleration voltage, 8 mm operating distance, high current, and processing time conditions. The color, shape, and dimension of achene have macro‐morphologically shown variations. The examined achenes are separated into four shapes; fusiform‐oblong, oblong, oblong‐ovate, and ovate. Oblong‐ovate is the most common type. Achene dimensions range from 0.62 to 2.48 mm in length, and from 0.30 to 1.21 mm in width. Also, carpopodium diameter varies between 0.10 and 0.19 mm. Achene surfaces of the examined taxa are micro‐morphologically assessed, and substantial differences are noticeably detected on behalf of the surface structures for instance, surface ornamentation, anticlinal and periclinal cell walls, epidermal cells, and the presence of secondary structures of the achenes. Surface ornamentation is separated into 10 types: irregularly sulcate, regularly sulcate, ruminate, sulcate‐scalariform, rugose, favulariate, slightly sulcate, alveolate, tuberculate, and reticulate. A percentage comparison of the elements in the achene pericarp of the studied taxa has been performed with SEM‐EDS. Accordingly, pericarps in taxa include C, Ca, K, Mg, Cl, Si, Na, and S elements. In the taxonomy of the genus Artemisia, the achene morphological characters are very significant characteristics that disclose inter‐specific relations among the examined taxa. Moreover, a dichotomous key is offered for the identification of the studied taxa based on achene characters.Research Highlights The achenes of Turkish Artemisia taxa have been examined in depth. The morphological characteristics of achenes of Turkish Artemisia taxa have been studied using SEM and LM for the first time and debated the systematic practice of these characters. The elemental content of the achene pericarp has been systematically evaluated for the first time.
