The effect of industrial effluents was studied with respect to growth and leaf anatomy of three Sesamum indicum varieties (NGB 00931, NGB 00937 and NGB 00939). Industrial effluents (25%, 50%, 75% and 100%) from two industries are used to irrigate the plants. Although, the control plants possessed larger leaves and longer stems than the effluent-treated plants, at lower concentration, the plant growth is relatively higher. Gradual decrease in the germination of seeds and seedling growth with increase in effluent concentration was observed. The best germination and seedling growth was observed at the 25% concentration. Leaf epidermal features (stomatal density, stomatal index, stomatal size, trichome density, tricome index, trichome size and number of epidermal cells) are more influenced in the effluent-treated plants than in the control plants from the Peace Standard Pharmaceutical Industry than in the effluent from the Global Soap & Detergent Industry. Thus the industrial effluents can be safely used for irrigation purposes with proper treatment and dilution at 25%.Bangladesh J. Sci. Ind. Res. 52(1), 1-6, 2017

First Time

As the largest genus of broad leaved deciduous trees, Acer L. contains about 126 species distributed in the temperate regions of the Northern Hemisphere. With eight native species in Iran, maples are among the most important tree species in the country. Micromorphological traits of 39 populations of Iranian native species indicated the value of leaf epidermal characteristics in identification and classification of maples. A number of epidermal morphological features of the abaxial surface were investigated using LM and SEM images. The occurrence of stomata in clusters is reported for the first time in Acer. The shape of the epidermal cells, anticlinal cell wall patterns, type of indumentum, and epicuticular waxes were the most significant variables in this study. The ability of quantitative and qualitative variables in segregating the studied taxa was evaluated by statistical methods, including PCA, MCA and Non-parametric analyses.

Epidermal features were studied in all 17 species of Passerina, a genus endemic to southern Africa. Leaves in Passerina are inversely ericoid, the adaxial surface concave and the abaxial surface convex. Leaves are inversely dorsiventral and epistomatic. The adaxial epidermis is villous, with unicellular, uniseriate trichomes and relatively small thin-walled cells, promoting flexibility of leaf margins owing to turgor changes. In common with many other Thymelaeaceae, abaxial epidermal cells are large and tanniniferous with mucilaginous cell walls. The cuticle is adaxially thin, but abaxially well devel­oped, probably enabling the leaf to restrict water loss and to tolerate high light intensity and UV-B radiation. Epicuticular waxes, present in all species, comprise both soft and plate waxes. Epidermal structure proves to be taxonomically impor­tant at family, genus and species levels. Interspecific differences include arrangement of stomata and presence or absence of abaxial epidermal hair. Other diagnostic characters of the abaxial epidermal cells are arrangement,size and shape, cutic- ular ornamentation and presence or absence of wax platelets. Two groups of species on the basis of abaxial epidermal cell orientation are recognised. Many leaf epidermal features in Passerina are interpreted as structural adaptations to the Mediterranean climate of the Cape.

To investigate the possibility of using leaf epidermal characters for species identification in developing a classification for Maianthemum, we examined leaf epidermal features from across the geographic distribution of the genus, including sampling of 34 species, one subspecies and one variety, and used light and scanning electron microscopy to make observations of these features. Our results suggest that the shape of epidermal cells, and anticlinal walls on both the abaxial and adaxial leaf surface have systematic significance for defining Maianthemum taxa and are congruent with clades inferred using molecular phylogenetics. The pattern of anticlinal walls in the genus seems to be related to the geographic distribution and environmental conditions. Other characters yielded in this study including anomocytic stomata, elliptic to narrow elliptic guard cells, wrinkled, striate or nearly smooth cuticle, smooth or sinuolate to erose inner margin of the outer stomatal rim, are not useful for taxon circumscription in the genus.

Epidermal Features

The structures of the achene epidermal cells and their included silica deposits are illustrated and described for 28 species that have been referred to Carex section Hymenochlaenae. On the basis of these epidermal features, there are anomalous species in nearly all of the subsections and sections that have been circumscribed by Kükenthal, Mackenzie, Ohwi, and Koyama. Furthermore, some species with nearly indistinguishable achene surface features have quite different overall morphologies and have traditionally been placed in different sections. Similarities in the structure of the silica deposits in the achene epidermal cells may result from the retention of the primitive character state in several different lineages or from parallel development of modified silica bodies or wall structures in different lineages. Levels of homoplasy appear to be too high to make these characters reliable indicators of evolutionary relationships in Carex section Hymenochlaenae.
