“…Comprehensive micromorphological studies of the genus Crataegus in Iran (Hamzehee et al unpubl.) as well as results of this paper, together with other previous treatments (Christensen and Hansen 1998, Ganeva et al 2009) show that micromorphological features are useful for the separation of Crataegus taxa.…”

In the context of systematic and biosystematic studies on Eurasiatic Crataegus (Rosaceae, subtribe Pyrinae) based on leaf and petal SEM photographs and morphological features, Crataegus khatamsazae Hamzeh'ee, K. I. Chr. & Attar sp. nov. and C. hatamii Hamzeh'ee, K. I. Chr. & Attar sp. nov. are described as new taxa, and C. caucasica is reported as a new record to Iran. Crataegus aminii is found to be synonymous with C. babakhanloui and not with C. ambigua subsp. ambigua. The description of C. kurdistanica is improved. The situation for C. sakranensis in Iran is discussed and its morphological characterization is improved. A new identification key to the recognised Iranian taxa of subser. Erianthae is provided and the distributions of these taxa are outlined.

“…Molecular phylogenetic studies have suggested that epicuticular waxes could also include a phylogenetic signal (Heo et al 2013). The rodlet type of epicuticular wax with differences in diameter of the base was described for the first time for Maloideae (Ganeva et al ), although various types – granules, plates and platelets – have been reported for some species of the genera Crataegus (Ganeva et al ), Pyracantha , Mespilus , Cotoneaster (Uzunova and Mladenova ) and Malus (Ganeva and Uzunova ).…”

“…Characters of the leaf epidermis have proved useful for the classiﬁcation and identiﬁcation of difﬁcult taxa such as Pinus (Whang et al 2001), basal angiosperms (Carpenter ), Salix (Chen et al , Ghahremaninejad et al ) and Scorzonera hispanica (Chwil et al 2015). Regarding Rosaceae, studies have been conducted on some genera: Rosa (Wissemann ), Cydonia (Ganeva ), Crataegus (Ganeva et al ), Malus (Ganeva and Uzunova ), Amelanchier (Ganeva and Uzunova ), Sibbaldia (Tahir and Rajput ) and Pyrus (Zamani et al 2017). Also in these genera have some such characters, e.g.…”

In this study, micromorphological features of the leaf epidermal cells of 17 species of Iranian Cotoneaster were determined. The studied species were compared with each other and with phylogenetic relationships established by previous studies. Three populations of C. integerrimus and C. multiflorus were studied as representatives of C. subgen. Cotoneaster and Chaenopetalum, respectively. To evaluate quantitative and qualitative characters, multiple correspondence analysis (MCA) and factor analysis of mixed data (FAMD) were performed. Finally, relationships among the taxa were illustrated by hierarchical clustering analysis. Three stomatal types were identified, i.e. anomocytic, stephanocytic and actino‐stephanocytic. The wax and cuticle density was higher in species from semi‐moist habitats than in those from dry and semi‐dry habitats. The patterns formed by the anticlinal walls of the epidermal cells were sinuous, repand and straight‐curved. Interestingly, there was a significant relationship between the length of leaves, the density of the indumentum and the pattern formed by the anticlinal cell walls. The leaves of species with large leaves also have lower hair density and more curved anticlinal cell walls. It appears probable that climatic conditions affected the evolution of leaf micro‐morphological characters during the early diversification of the genus, but that these characters have subsequently been permanently fixed by phylogenetic constraints and thus appear diagnostic for extant species.

Isolation and recrystallization of epicuticular waxes from Sorbus and Cotoneaster leaves

et al. 2015

View full text Add to dashboard Cite

Wax morphology and chemical composition are widely accepted to be important for the protective properties of the leaf’s surface and also valuable characteristics in plant systematics. The leaves of Sorbus domestica L. and Cotoneaster granatensis Boiss., species of two large genera with intricate taxonomy referred to subtribe Pyrinae, Rosaceae (formerly subfamily Maloideae), were studied by scanning electron microscope (SEM) and performing different methods of wax isolation. The aim of the study was to acquire a suitable, cost and time effective method for wax removal. Chloroform and methanol extractions and freeze-embedding method for direct isolation of the wax crystals were applied. Immersing the leaves for 3 minutes in chloroform was sufficient to extract the waxes whereas the efficiency of the methanol solvent was lower. Wax layers with wellpreserved structures of the crystals from both upper and lower epidermis were successfully transferred to artificial surfaces. The recrystallization experiment demonstrated that waxes from chloroform extracts could recrystallize in in vitro conditions on artificial surfaces. The crystals showed same micromorphology as on the intact leaves. Results of this study could be applied in further analytical researches of the waxes of S. domestica and C. granatensis or other species of the subtribe Pyrinae.
