“…The results obtained from morphological studies are consistent with description given in the Cullen (1965), Yüzbaşıoğlu et al (2015) and Dönmez et al (2017). Seed coat patterns are used for solving classification problems, establishing evolutionary relationships, elucidating the adaptive significance of the seed coat, and serving as genetic markers for the identification of genotypes in segregating hybrid progenies (El-Naggar, 2005;Bona, 2013;Karaismailoğlu and Erol, 2018;Gabr, 2018;Ozcan and Akinci, 2019). Seed micromorphology of Aubrieta taxa from Turkey was studied before by Yüzbaşıoğlu et al (2015;A.…”

The aim of this study was to document the taxonomical, morphological, anatomical, palynological and cytological characters, and geographical distribution of endemic Aubrieta pinardii Boiss. (Brassicaceae) from Turkey. The description of the taxon was revised as a consequence of comprehensive assessments of many specimens. The surface pictures belonging to seed and pollen of the taxon were obtained by Scanning Electron Microscope. The seed surface ornamentation was rugose. The pollen was radially and isopolar and prolate in forms, with polar axes of 19.52 ± 0.29 μm and equatorial axes of 13.04 ± 0.22 μm, with oval outlines in the equatorial axes, and elliptical in the polar axes. They were three–colpate and colpus sizes varied between 12.98 μm and 13.29 μm in length, and between 1.33 and 2.09 μm in width. Also, the anatomical structures of the root, stem and leaf of species were studied. In cytological studies, the chromosome number of species was found as 2n = 16 (x =8). This was the first work including taxonomical, morphological (macro and micro), anatomical and cytological data of endemic Aubrieta pinardii. Bangladesh J.Plant Taxon. 27(1): 27-35, 2020 (June)

“…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.…”

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.

“…In taxonomic studies, it is seen that only the use of morphological characters is insufficient and therefore, the necessity of anatomical, cytological, molecular, palynological studies etc. is revealed [5].…”

Species of Carlina corymbosa L., Carthamus dentatus Vahl. and Picnomon acarna (L.) Cass. are belonging to Asteraceae family. The purpose of the study is to determine the anatomical structures of these species in the same tribe and to compare the features. Samples of root, stem and leaf of each species were collected, fixed and examined using a light microscope. In addition, some anatomical features were measured. Secondary growth was observed in the root cross section of each species. Secretory ducts were determined in all species. While the pith is filled with xylem elements in C. corymbosa and C. dentatus, the pith of P. acarna consists of different shaped parenchyma cells. Periderm was observed in the stem in all species. All species contain bicollateral vascular bundles in stem. In all species, glandular and nonglandular trichomes were observed on the leaf cross section, on the surface of the adaxial and abaxial epidermis. While C. corymbosa has dorsiventral mesophyll, unifacial mesophyll is observed in other species. There is bicollateral vascular bundle in C. corymbosa whereas collateral vascular bundle was identified in C. dentatus and P. acarna. Also, C. corymbosa and C. dentatus have only one vascular bundle in the midrib but P.acarna has three vascular bundles.
