“…Due to similarities between A. hyrcanum and A. mazandaranicum , there is a necessity to revising their taxonomic positions and considering the possibility that they belong to one taxon. Micro-morphological study of leaf by Mohtashamian et al in 2017 showed that the structure and shape of epidermis cannot separate A. mazandaranicum and A. hyrcanum as two species. Therefore, it can be concluded that these two species are very close and A. mazandaranicum may be similar to A. hyrcanum.…”

Asadi F, Sharifnia F, Salimpour F, Majd A. 2019. Using micro-morphological fruit characters in resolving some of ambiguities in Iranian Acer L. (Sapindaceae) species. Biodiversitas 20: 297-304. Acer L. belongs to the Sapindaceae family consists of 126 species which are distributed in the temperate regions of the northern hemisphere. There are 12 taxa (including Acer monspessulanum with four subspecies and Acer velutinum with two varieties) in Iran. In this study 21 fruit characteristics are partially investigated using Scanning Electron Microscope (SEM) and Stereomicroscope. According to the obtained results, four types of faveolate, folded, wrinkled and pavement wing surface ornamentations as well as four types of faveolate, folded, verrucous, and wrinkled achene surface ornamentations were observed. Hair of wing margin, achene hair, wing ornamentation, inside angle of wing, and outside angle of wing have taxonomic value. According to fruit morphology, separation of 4 subspecies of A. monspessulanum can be verified. Also varieties of A. velutinum var. velutinum, and A. velutinum var. glabrescens were totally separated due to differences in characteristics such as wing ornamentation, achene ornamentation, hair density of achene, wing length, wing width, the ratio of length to width of wing, total fruit length, total fruit width, the ratio of length to width of fruit, inside angle of wing, outside angle of wing. The results showed that micro-morphological fruit characters of Acer genus are valuable in terms of taxonomy and classification of subspecies level.

“…The morphological characters of plant leaves serve as a useful instrument for infrageneric classification and species circumscription, and sometimes they also provide significant information regarding the phylogeny and taxonomy of closely related species (Stace 1969 ; Baranova 1992 ; Meng et al 2016 ; Ullah et al 2018 ; Shaheen et al 2021 ; Bashir et al 2020 ). High intraspecific consistency may be shown by foliar epidermal characters, although diversity is seen at the interspecific and higher taxonomic levels (Wang et al 2015 ; Mohtashamian et al 2017 ). Therefore, leaf epidermal features, such as epidermal cell shape, stomatal type, size and distribution, and trichome type and distribution, have played an essential role in distinguishing those families and genera where identification is complicated, such as Salicaceae (Ghahremaninejad et al 2012 ), Caryophyllaceae (Ullah et al 2018 ), Fabaceae (Silva et al 2018 ; Shaheen et al 2021 ; Zhao et al 2022 ), Lamiaceae (Gul et al 2019 ) and Poaceae (Khan et al 2017 ).…”

Background Leaf morphology and epidermal characters are important for phylogenetic and taxonomic studies of many plants, but there is currently insufficient data to use them to help distinguish species of Gagea, which is a taxonomically difficult genus mainly due to polyploidy and hybridization. Therefore, leaf morphology and epidermal characters of Gagea were studied to assess the characters that can be used to elucidate the taxonomy and systematics of 14 species of Gagea collected in Xinjiang, China. Using light microscopy (LM), six qualitative and three quantitative leaf epidermal anatomical characters were examined for both the adaxial and abaxial surfaces. Hierarchical cluster analysis (HCA) was employed to reveal the similarities based on leaf morphology and epidermal characters of the investigated species. Results Basal leaf of these species can be terete or flat, and it is triangle, flat, or circular in transverse section. Anticlinal wall patterns of the leaf epidermal cells were straight and sinuous, and only three species had epidermal hairs. Shape of long cells varies, ranging from quadrangular to irregular. HCA revealed that the 14 species could be divided into two groups. Group A was arranged into three subgroups (A1, A2 and A3), based on the Euclidean distance of 6.96. Subgroup A1 consisted of three species with indumentum; subgroup A2 had four species with sinuous type anticlinal walls; and subgroup A3 comprised of two species with a fistulose basal leaf. Group B included five species with short cells. Conclusions Leaf morphology and epidermal characters did not differ significantly among populations of the same species in Gagea, whereas they differ significantly among species. Thus, leaf morphology and epidermal characters provide diagnostic information for differentiating G. nigra and G. filiformis; G. altaica, G. jensii and G. alberti, which are morphologically similar species.

Simaba sensu lato was recently splited in two distinct genera, Simaba senso strictu and Homalolepis, both with mainly South American distribution occuring in different environments and morphoclimatic areas. Although their phylogenies are almost fully understood, some species still require attention. Studies with cuticular waxes have showed the usefulness of these characters in some phylogenies. Despite the great number of data concerning the chemical analysis of species of Simaroubaceae related to quassinoid composition, for the best of our knowledge there is no study with the chemical and morphological characterization of the cuticular waxes on this family. Therefore, in the present study, the chemical composition and the morphology of the leaf cuticular waxes of 119 specimens belonging to 20 species of Homalolepis, four from Simaba s.s. and three from related genera were analyzed. The waxes were extracted with dichloromethane and analyzed by gas chromatography coupled to mass spectrometry. The morphology of the epicuticular waxes was analyzed by scanning electron microscopy. Seventy compounds were identified in the waxes, comprising fatty acids, alkanes, primary alcohols, steroids and tocopherols. The most abundant classes were the fatty acids and alkanes. While fatty acids were the major class in Homalolepis, alkanes were more abundant in Simaba s.s. This quantitative distinction allowed the differenciation of the two genere. Notwithstanding, the composition of the waxes were very similar, as well as their morphology. Consequently, these data were not helpful in distinguishing the species. Concerning the wax composition in relation to the morphoclimatic areas, the speciemens collected in the Atlantic and Amazonian domains had thiner wax loads than those collected in the Cerrado. However, almost none correlation was found between wax chemical classes and the morphoclimatic area, except for the predominance of alkanes in the specimens collected in the Amazonian domain.
