Taxonomic evaluations on the anatomical characters of leaf and achene in Turkish Tripleurospermum with its relative Matricaria (Asteraceae)

The Genus Tripleurospermum Sch. Bip. (Asteraceae): A Comprehensive Review of Its Ethnobotanical Utilizations, Pharmacology, Phytochemistry, and Toxicity

“…Furthermore, the outermost layer of this genus’ leaves has been identified as a significant factor in taxonomic differentiation and to play a role in the development of stomatal complexes, including those found in achenes [ 30 , 31 ]. It is worth noting that anatomical features such as stomatal length, vascular bundle size, and palisade sclerenchyma thickness are important for distinguishing between Tripleurospermum species and for establishing a correlation between ploidy level and anatomical structures across different Tripleurospermum species [ 22 , 32 ].…”

“…The stomata of Tripleurospermum species are distributed on both the upper and lower surfaces of their leaves, with equal stomatal density reported [ 22 ]. Stomatal characteristics such as stomatal frequency, guard cell length, and stomata plastids’ diversity have been used as morphological indicators for assessing ploidy levels in different plant species [ 33 , 34 , 35 , 36 ].…”

“…The leaf anatomy of Tripleurospermum species bears similarities to that of Matricaria L. [ 22 ]. The leaf anatomy of Turkish Tripleurospermum taxa typically consists of lower and upper epidermis, parenchymatous mesophyll, and a vascular bundle [ 46 ].…”

Pappus and fruit micromorphology and fruit anatomy in some members of the tribe Cardueae (Asteraceae) from Turkey with their contributions to systematics

“…The morphological and anatomical features of the fruits have already been successfully used to better understanding the taxonomic relationship in the family Asteraceae (Funk, Susanna, Stuessy, & Robinson, 2009; Inceer et al, 2018; Inceer & Ozcan, 2021; Jana & Mukherjee, 2012; Lavialle, 1912; Pandey & Singh, 1982). The important fruit characters in the tribe Cardueae have been revealed by some authors (Ghimire, Gang, Lee, Heo, & Jeong, 2018; Häffner, 2000; Lavialle, 1912; Ozcan, 2017, 2018; Ozcan & Akinci, 2019; Zarembo & Boyko, 2008).…”

A tale of two chamomiles: profiling the differences between Tripleurospermum tempskyanum (Freyn & Sint.) Hayek and Matricaria recutita L

“…Until recently, the multitude of morphological similarities constituted a cause of taxonomic confusion among botanists, with several Tripleurospermum species being attributed to the Matricaria genus in nomenclature. Nevertheless, in recent years, studies around the genome of those plants assisted to the definite separation of the two genera 1 . In this context, the present work describes the phytochemical investigation of the aerial parts of the common chamomille, M. recutita (Mr) and T. temspkyanum (Tt), a rare species which has only been encountered in certain parts of Greece and Turkey.…”
