“…Considering that the endosperm cell walls are thickened, it apparently serves as an additional protective layer for the embryo (Jeffrey 2007). According to Jeffrey (2007), the endosperm and seed consist of living cells that are rich in oil and protein, but devoid of starch, which is in line with our results (Karanović et al 2016).…”

Achene anatomy and stomatal characteristics of eighteen Crepis taxa from Turkey are here described for the first time. In all taxa examined the pericarp is composed of several layers of sclerenchymatous and parenchymatous cells. As for the achene, differences among taxa mainly concern the pericarp structure and its thickness and width. Stomata are present on both surface of the leaf in all studied taxa and all taxa have anomocytic type stomata. However, the dimensions (length and width) and density of the stomata differ significantly among the studied taxa. In addition, the dimensions of stomata are negatively correlated with stomata density. It is concluded that achene anatomy and stomatal characteristics are useful for delimitation of Crepis taxa and a key to taxa based on these characters is provided. However, based on achene anatomy and stomatal characteristics, we found no argument for an exclusion of the Lagoseris group from Crepis as has previously been proposed.

“…Achene features with morphological structures and pappus form are generally used for the taxonomy and limitation of various taxa in tribe Lactuceae (Aksu Kalmuk, Inceer, & Imamoglu, ). The Cypsela microcharacters including surface sculpture and pappus ultrastructure provide supplementary informative data for delimitation of the genera and identification of taxa in Lactuceae (Aksu Kalmuk et al, ; Karanović, Zorić, Zlatković, Boža, & Luković, ; Zhang et al, ). The Cypsela that is one‐seeded fruit in tribe Lactuceae is absolutely necessary for identification of the genera and species and its morphology contributes the systematically most valuable data at all taxonomic levels (Inceer et al, ; Sennikov & Illarionova, ; Zhu et al, ).…”

The current study deals with the detailed morphology investigation of eight Cypsela species belonging to tribe Cichoreae. The different Cypsela types were described, explained, compared, and their taxonomic significance is discussed in detail. Light microscopy (LM) and scanning electron microscopy (SEM) have been used to highlight quantitative and qualitative characters of underestudied species. Cypsela exhibit great diversity in macro and micromorphological features such as shape, color, length, width, anticlinal and periclinal wall patterns, surface patterns, epicuticular projections. Majority of Cypsela species were brownish in color and their size ranges from 2.16 to 3.98 mm in length and 1.16 to 0.82 mm in breadth. A great diversity in Cypsela shapes like oblanceolate to obovate, obovoid to cylindrical, obvate, narrowly lanceolate were observed. Most of the platelets having epicuticular projections were observed. The surface pattern on the cypsela surface varied from rugose papillate, verrucose papillate, and striated. On the basis of considerable variations observed, the present study can assist as useful constraints at various taxonomic levels. The aim of the present study is to provide a comprehensive description of the Cypsela morphology and to determine the extent to which these micro morphological data can be used as a taxonomic character to delineate various taxa belonging to the tribe Cichoreae.

“…Secretory ducts were situated in the internal layer of cortex, between sclerenchyma strands. Despite the great importance of the fruit features in taxonomy, little data can be found in the literature on micro-morphological and anatomical characters of Inula fruit (Abid and Qaiser 2002;Jana et al, 2013;Karanović et al, 2016). The mature fruit of I. oculuschristi is differentiated into cypsela and pappus ( Figure 3A).…”

Inula oculuschristi L. is a perennial plant, 20-60 cm high, growing in southeast Europe, central and southern Russia and some parts of Asia. It belongs to Pontic-Pannonian floristic element. In Pannonian part of Serbia this species is extremely rare, with very few recently confirmed literature and herbarium data. According to the field data for the period from 2013 to 2015, only one population of this species was recorded in Pannonian part of Serbia, on the site of Rimski Šanac, which is threatened by anthropogenic activities. Furthermore, anatomical and micro-morphological features of I. oculuschristi have not been documented so far. Therefore, in order to get better knowledge of the biology this species, as well as on the basis of the abovementioned, its anatomical and micro-morphological characteristics were investigated. Cross sections of the leaf, stem, rhizome and fruit were obtained using cryotechnique procedure by Leica CM 1850 cryostat. Using a light microscopy, detailed descriptions of anatomical characteristics of the analysed organs were given. The scanning electron microscopy revealed specific qualitative features of leaf and fruit that characterize the species. Obtained data may be useful in determination of this species and represent the valuable contribution to its micro-morphological and anatomical differentiation from other congeneric and related species.
