“…The setae surface of those species cover dense or sparse papilae, where setae of O. stenoloba consist of tubercles with pilies at the base. The findings based on anatomical and micromorphological studies were found somewhat consistent with those of Akçin and Engin (2001), and Akçin and Binzet (2010). However, our results differs from those earlier studies in terms of number of layers of cells and tissues, the density of trichomes and the types of leaf mesophyll (Fig.…”

“…Metcalfe and Chalk (1950) studied the anatomy of the family Boraginaceae and found setae (hairs), epidermal surface and cystoliths as diagnostic characters. Several attempts have been made on micromorphology and anatomy of different Turkish species of Onosma Engin, 2001, 2005;Akçin, 2004Akçin, , 2007Binzet and Akçin, 2009;Akçin and Binzet, 2010). Micromorphological studies of epidermal and nutlet surface of some Onosma taxa highlighted the importance of these features (Akçin, 2009;Binzet and Akçin, 2009;Akçin et al, 2013;Mehrabian et al, 2014).…”

Micromorphology and anatomy of six Onosma L. species, viz. O. argentata Hub.-Mor., O. neglecta Riedl, O. proballanthera Rech. f., O. rechingeri Riedl, O. sericea Willd. and O. stenoloba Hausskn. ex Riedl from Turky were investigated. Stem anatomy revealed that cuticle layer ranged from 0.6 µm in O. argentata to 1.7 µm in O. proballanthera. Parenchymatous cells of O. neglecta and O. stenoloba possessed more intense starch than the other species studied. In leaf anatomy, the longest palisade parenchyma was found in O. neglecta, while the smallest was noted in O. argentata. Mesophyll structure of O. argentata, O. sericea and O. rechingeri was equifacial (isobilateral), while O. neglecta, O. proballanthera and O. stenoloba presented bifacial (dorsiventral) structure. Rugose nutlet ornamentation was observed in O. argentata, O. neglecta and O. sericea, whereas reticulate type was found in O. proballanthera, O. rechingeri and O. stenoloba. Onosma stenoloba could easily be distinguished from other species by its aesterotrichous indumentum, and in contrary, other species possessed haplotrichous type of indumentum. Micromorphological features of nutlet surface, anatomical features of epidermal surface (trichomes and stomata), and lamina mesophyll structure (dorsiventral and isobilateral) could be useful in solving taxonomic problem of the genus.

“…Trend from heterogenous to homogenous has been noted as a reliable tool to infer specialization; a primitive position for heterogenous rays and an advanced position for homogenous wood rays have been suggested (Outer and Veenandal, 1997;Folorunso and Awosika, 2013 The study of the leaf epidermal surfaces of Ludwigia revealed a number of important micromorphological characters and these characters exhibit interesting variations that are of significance for identification. These findings support previous studies in some other genera where leaf and stem anatomical characters have been used as a veritable taxonomic tool (Adedeji and Illoh, 2004;Saheed and Illoh, 2010;Akçin and Binzet, 2010;Folorunso and Awosode, 2013).…”

Foliar and stem anatomical characters that could be used for the identification of nine species of Ludwigia L. viz., Ludwigia abyssinica A. Rich., L. adscendensoctovalvis variety brevisepala (Jacq.) Raven and L. octovalvis variety linearis (Jacq.) Raven in Nigeria are reported. This is envisaged to facilitate the management of these Ludwigia species; most importantly the invasive species and also to reduce the fluctuations in their taxonomic classifications. Fresh leaves and matured stem of these nine (9) species of Ludwigia from South-western Nigeria were subjected to anatomical study under Light Microscope. The occurrence of hypoamphistomatic stomata and several other stomata types such as anomocytic, staurocytic, anisocytic, cyclocytic and laterocytic in these advanced species of Ludwigia could be responsible for their invasiveness in the environments. Similarly, the mean vessel diameter in Ludwigia species studied represents invasive character; the species with higher mean vessel diameter are likely to be more invasive in their habits. Baseline information on the stem anatomy of the Ludwigia species has been provided; in addition, diagnostic characters for easy identification and classification of the taxa are also reported. The leaf and stem anatomical characters in the Ludwigia species are constant despite their environmental plasticity.

“…Although the polytomies obtained in Weigend et al Anatomical and morphological characters to indicate phylogenetic relationships among taxa (Metcalfe & Chalk, 1979). Also, it is well known that anatomical traits provide taxonomically significant data in the numerous angiosperms including Boraginaceae family (Akçin & Binzet, 2010;Beyazo glu, Türkmen, Coşkunçelebi, Makbul, & Kodal, 2008;Binzet & Akçin, 2012;Coşkunçelebi, Makbul, Türkmen, & Beyazo glu, 2008;Makbul, Türkmen, Kandemir, & Beyazoglu, 2008). Metcalfe and Chalk (1979) pointed out that family Boraginaceae has both bifacial and isobilateral leaves.…”

Foliar and stem epidermal anatomical features of the tribe Cynoglosseae have been studied in detail for the taxonomic identification using light microscopy (LM) and scanning electron microscopic (SEM) techniques. A comparative study was conducted on different plant parts (leaf and stem epidermal anatomy) of 25 species belonging to eight genera of the tribe Cynoglosseae (Boraginaceae) collected from different phytogeographical regions of Iran for the first time. Different qualitative and quantitative characteristics were observed in detail using LM and SEM. Results showed that although generally the stem and leaf anatomical traits were similar, but some diagnostic features were examined for distinguishing the closely related genera in the tribe. The ratio of cortex/diameter of stem and phloem/xylem, the average row number of collenchyma, palisade and spongy cells, structure of trichomes, type of indumentum and palisade arrangement were found taxonomically important. The anatomical characters were statistically analyzed using cluster analysis and principal component analysis. The study found that stem and leaf eccentrics are variable in the genus but constant within species of the same genus. Most species had typical isobilateral leaves, but some showed an incipient dorsoventrally symmetry with a layer of abaxial palisade tissue. Eglandular trichomes were observed found in all the studied species, which were recognized based on structure and function. In present study some novel characters have been observed which are of great interest to the taxonomist for the correct identification some genera delimitations. The characters studied here are of less taxonomic value and delimitating at species level.
