Morphological variations of acorn among and within the groups of Quercus species were studied. A total of 617 acorns belonging to 14 species representing all 3 sections of Quercus L. (Fagaceae) in Turkey were examined in this study. Specimens were collected from 47 different populations over both Anatolian and Thrace part of Turkey. Principal component analysis was used to analyze the morphological characteristics of acorns. Results obtained from this study demonstrate the use of morphological characters in differentiating the taxa of Quercus and Cerris sections studied. Another important finding is the introgression among the acorns of species within Quercus section DOI: http://dx.doi.org/10.3329/bjb.v43i3.21601 Bangladesh J. Bot. 43(3): 293-299, 2014 (December)

The heteroptera is an important suborder of order hemiptera and includes a large number of aquatic and semiaquatic forms, which are of a taxonomic importance. The study recorded 14 families namely Napidae, Notonectidae Pleidae, Belostomatidae, Naucoridae, Corixidae, Gelastocoreidae, Ochtaridae, Hydrometridae, Velidae Mesoveliidae, Gerridae, Saldidae and Herbridae. Aquatic and semiaquatic heteropteran insects are of variable sizes from 1.5 mm. to 110 mm long living mainly in lentic and lotic fresh water. Some even live in brackish water, only a few species are marine. These are different in morphology and feeding habits from their terrestrial forms. Some are truly aquatic, provided with effective swimming respiratory structure along with modification of body shape and size. Besides the genitalia and copulatory complex of all the species studied has been dealt. The other morphological features of taxonomic significance were also studied. This study finds various morphological features in the members of different aquatic and semiaquatic families of heteroptera.

The objective of this work was to evaluate leaf epidermis morphological characteristics of three citrus somatic hybrids, compared to their parents. Parental and somatic hybrid young leaves were collected and processed for scanning electron microscope observations. Citrus polyploid hybrids have fewer stomata per area and these are larger compared to their diploid parental parents. No differences in internal arrangement of the stomatal cells were detected between parental plants and somatic hybrids. Additional studies may determine if these differences will influence physiological behavior of the plants in the field.

The nutlet morphology of 11 taxa of Mentha L. (M. pulegium, M. aquatica, M. × piperita, M. x dumetorum, M. spicata subsp. spicata, M. spicata subsp. tomentosa, M. × villoso-nervata, M. longifolia subsp. longifolia, M. longifolia subsp. typhoides, M. × rotundifolia and M. suaveolens) distributed throughout Turkey was investigated by scanning electron microscopy (SEM). The shape of all studied nutlets was broadly oblong or ovoid. Nutlet size ranged from 0.54 to 0.97 mm in length and from 0.37 to 0.66 mm in width. The smallest and biggest nutlets were found in M. × villoso-nervata and M. aquatica, respectively. The Mentha taxa studied can be divided into three groups, based on nut sculpturing type such as distinctly bireticulate, inconspicuously bireticulate and reticulate. This study has shown that some nutlet morphological characteristics can be utilised as additional diagnostic characteristics in delimitations of Mentha at the species and infraspecific levels.

Abstract Anatomical characters of two morphologically similar Ornithogalum taxa, O. umbellatum and O. divergens, were investigated. An analysis of leaf and scapus cross-sections was performed on plants from ten populations from Serbia and Hungary, using light microscopy. The aim of this research was to give data about the qualitative and quantitative anatomical characteristics of these taxa, in order to evaluate their taxonomic significance and single out distinctive anatomical features, as well as to contribute to the knowledge of the genus Ornithogalum in the studied region. On the basis of the variability of anatomical characters, similar populations formed two clusters, joining the plants previously determined as O. divergens and O. umbellatum. The two taxa significantly differed for most of the quantitative leaf and scapus characters. Since only quantitative differences were recorded in this research, anatomical characters could not be solely used to separate these two taxa. However, the results of anatomical investigations are consistent with the results of previous morphological and genetic analyses; therefore anatomical parameters could be useful as additional taxonomic characters.

AbstractIn this study, for the first time, the morphology of the dorsal and ventral skin of Triturus karelinii using light microscopy through histochemical methods was described. The skin exhibited basic morphological characteristics of the other urodeles: the epidermis composed of keratinized stratified epithelium with numerous conical protrusions and the dermis subdivided into spongy and compact layers. In the spongious dermis, three distinct types of glands were observed, namely serous, mucous and mixed glands. These glands were alveolar and occurred in both males and females. The morphologies of all three skin glands differed from anurans and other urodeles, having peculiar characteristics. Serous glands exhibited three different appearances. An unusual finding in mucous glands was the different appearance of their granules, showing diverse density after staining with PAS and AB. The histochemical analysis clearly demonstrated the presence of neutral, acid and sulfated mucins in the adenocytes of mucous glands. Mixed glands formed by mucous and serous glands exhibited the same morphological traits of both types of glands. Light microscopic observations revealed that the dorsal and ventral skin showed structural similarities with some minor differences, possibly resulting from their functions.
