“…The kinds of anticlinal and periclinal cell walls, and epidermal cell forms of the examined taxa disclose differences among taxa. The macro and micro-morphological results of this search are separated all taxa studied from each other, and they are consistent with the previous works including the exomorphic characters of achenes of the family Asteraceae (Karaismailoglu, 2015;Coşkunçelebi et al, 2016;S ¸irin et al, 2017;Özbek et al, 2018;Bona, 2020;Ayaz et al, 2020;Vakulenko et al, 2020;Bona et al, 2023).…”

“…The morphological structures of the achenes offer important data in connection with evolutionary relationships of the flowering plants (Corner, 1976;Karaismailoglu, 2015). Achene morphological characteristics have so far been comprehensively performed to elucidate inter-species relatives within various genera of the family Asteraceae (Karaismailoglu, 2015;S ¸irin et al, 2017;Ghimire et al, 2018;Bona, 2020;Bona et al, 2023). This is the first investigation to display the morphological features and elemental contents of the achenes of TurkishArtemisia , and it could be a pioneering work for next studies in many related genera.…”

In the study, the achene macro and micro morphological characters of the genus Artemisia distributed in Turkey have been researched with the target to know systematically important carpological structures for the examined species. Color, shape and dimension of achene have macro-morphologically shown variations. The examined achenes are separated into 4 shapes; fusiform-oblong, oblong, oblong-ovate and ovate. Oblong-ovate is the most common type. However, oblong is typical form for A. abrotanum. Achene dimensions range from 0.62 mm to 2.48 mm in length, from 0.30 mm to 1.21 mm in width. As A. santonicum subsp. patens is of the largest achenes , A. annua and A. verloitorum have the smallest achenes. Also, carpopodium diameter vary between 0.10 mm and 0.19 mm. The largest carpopodium diameter is found in taxa A. fragrans and A. taurica var. vanensis , while the narrowest one is A. alpina species. Achene surfaces of the examined taxa are micro-morphologically assessed, and the substantial differences are noticeably detected on behalf of the surface structures for instance, surface ornamentation, anticlinal and periclinal cell walls, epidermal cells and 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. The most common types are irregularly sulcate (in 7 taxa) and regularly sulcate (in 7 taxa), while ruminate (in A. abrotanum), rugose (in A. chamaemelifolia), favulariate (in A. arborescens), alveolate (in A. santonicum subsp. patens), tuberculate (in A. taurica var. vanensis) and reticulate (in A. bashkalensis) ornamentation types are found as taxon-specific. A percentage comparison of the elements in the achene pericarp of the studied taxa have performed with SEM-EDS. Accordingly, pericarps in taxa include C, Ca, K, Mg, Cl, Si, Na and S elements. The most common seen element is C, which ranges from 77.4 (in A. austriaca) to 96.2 (in A. absinthium). Na element is observed only in A. santonicum subspecies and A. arborescens species. On the other hand, S element is found in low amounts only in A. alpina species. 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.

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.
