The micromorphological and anatomical characters of Elytrigia caespitosa (K.Koch) Nevski , E. intermedia (Host) Nevski × E. elongata (Host) Nevski, E. intermedia(Host) Nevski and  E. repens (L.) Desv. ex Nevski have been studied using Scanning Electron Microscope (SEM) to determine interspecific variation. The results show that the root transverse section consists of epidermis, cortex and stele. Two rings of vascular bundles and a central pith cavity appear in stem morphology. The leaves of  E. caespitosa have either single or twin, horse shoe-shaped short cells born along the costal zone of the upper epidermis, which lack prickle hairs and contain spherical or oblique-shaped papillae. In  E. intermedia, the parallel subsidiary cells are distributed on the upper epidermis, and there are no short cells in the leaves. Dome-shaped subsidiary cells appear on the upper epidermis of  E. intermedia × E. elongata and E. repens, but E. intermedia × E. elongata showes spot-shaped papillae, and its bulliform cells sank into the “hinge cells”. E. repens has no papillae, and its bulliform cells are not sunken into the mesophyll. Therefore, the differences in micromorphological characters on the upper epidermis of the leaf could be useful in classifying and determining phylogenetic relationships among the species.DOI: http://dx.doi.org/10.3329/bjpt.v20i2.17388Bangladesh J.

Introduction: Paliurus spina-christi Mill is a species with two varieties namely Paliurus spina-christi L. var. spina-christi and Paliurus spina-christivar. macrocarpa Beck native to mountains of Kurdistan, rarely growing in the upper plains of northern Iraq. Materials and Methods: A total of 15 plants from different parts of Kurdistan region were sampled. 30measurements for each characters of Leaf, Inflorescence, Flowers, Fruit, seeds, and leaf anatomical characters were measured for comparison between the two varieties. Results and Discussion: Fruit diameter of var. macrocarpa is significantly larger than fruit diameter of var. spina-christi. Most mean flower parts especially the ovary, in addition to seed size is larger in var. macrocarpa. Upper epidermal layer is always thicker than the lower epidermal layer for the same blade. The isobilateral mesophyll includes 2 layers of long palisade cells adaxially and 2-3 layers of short cells abaxially. Many vascular bundles are seen equally spaced in the mesophyll tissue.With the exception of the presence of simple hairs on the petiole adaxial side of the var. spina-cristi and the absence of these hairs from the same site of var. macrocarpa, all other anatomical features are considered to be of no taxonomic application. Stomatal density of the adaxial leaf side is up to 19 stomata per mm² in var. spina-christi while it is up to 38 stomata per mm² in var. macrocarpa. Conclusions: Both fruit diameter and the stomatal density of the adaxial leaf side constitute diagnostic characters for separating between the two varieties of Paliurus spina-christi Mill

Micromorphological characters of achenes in seven taxa of Turkish Achillea L. (Asteraceae) were investigated using stereomicroscope and scanning electron microscope (SEM). Some morphological descriptions of achenes were given for each species. A.biserrata Bieb. has the biggest (0.69±0.092 x 2.01±0.252 mm) and A. grandiflora Friv. has the smallest (0.30±0.018 x 1.12±0.058 mm) achenes. The achenes are oblong-lanceolate in A.biserrata and A. teretifolia Willd. and they are oblong in the remaining taxa. In surface sculpturing, the ornamentation and slime cell distribution varied among the taxa. However, A. biebersteinii Afan. has distinct slime cells forming groups scattered over the achene surface. Mature achenes are ribbed and glabrous in all studied taxa. A. biserrata has distinct carpopodium structure.DOI: http://dx.doi.org/10.3329/bjpt.v21i1.19253Bangladesh J.

AbstractSalvia macrochlamys Boiss. & Kotschy, which belongs to sect. Salvia Hedge, is a perennial herb usually growing on rocky limestone slopes in eastern Anatolia. In this study, the anatomical features of the root, the stem, the leaf and the petiole, as well as micromorphological characteristics of the pollen and the nutlet of this species have been investigated using Scanning Electron Microscopy (SEM). Moreover, its emended and expanded description, phenology, current distribution and ecology are also given. Anatomical characters such as the number of ray lines in the root, the distance between vascular bundles in the stem, the structure of mesophyll in the leaf and the structure of vascular bundles in the petiole have been found to have taxonomic value. The pollen grains are hexacolpate, radially symmetrical, isopolar and oblate-spheroidal. Their exine sculpturing is bireticulate and perforate. The nutlets are rounded-trigonous in transverse sections, broadly ovate to rotund in shape, light brown, glabrous and slightly rough to protuberances. This species often grows in habitats in which the main soil type is sandy-clayish with low organic content (1.32 ± 1.06%) and slightly alkaline (pH 7.75 ± 0.25). The amount of CaCO3 is 0.94% to 34.91%. The contents of P and K are 8.68 ± 0.96 and 110.12 ± 4.86 ppm, respectively.

Micromorphological Characters

Leaf epidermal features are very important in grass systematics for characterization of broad groups, within subfamilies and tribes. Numerous species belonging to sub-tribe Ischaemineae, tribe Andropogoneae, family Poaceae are endemic to the Indian subcontinent, but their micromorphological reports were very scares. Therefore, foliar micromorphological characters of subtribe Ischaemineae have been studied in detail for 16 taxa of subtribe Ischaemineae from Gujarat, India. All the epidermal peels were prepared after following routine scraping method, representative areas were photographed and presented here. Structural diversity as well as metric values for both the epidermises has been recorded. In general, intercostals zones and costal zones are uniform in nature in terms of sinuous papillate long cells, cross-dumbbell-nodular shaped silica cells and triangular-low domed shaped subsidiary cells on stomata. From all the studied micromorphological characters, papillae and microhairs are found to be most useful character to segregate species and genera in subtribe Ischaemineae. Additionally, intercostal silica bodies, hooks, prickles and bulliform cells are also found to be helpful for the same. An artificial key based on observed variable micromorphological features has been also prepared.

Abstract This paper reports on the assessment of morphological (macro and micro) and anatomical characters of seeds of Romulea taxa distributed in Turkey with the use of oneway analysis of variance, cluster analysis and principal component analysis. Morphological characteristics such as size, shape, color and surface of seeds were examined with the use of light and scanning electron microscopes. Thicknesses of testa and phytomelan layer, sizes of embryo in seeds were studied anatomically. The outcomes revealed that taxa were similar in some aspects such as color and shape of seeds. However, seed size, thickness of testa and phytomelan layer, shape of the epidermal cells in testa and sizes of embryo were different among taxa, and have taxonomic value in the distinction of these taxa from each other. In addition, the seed surfaces were more or less different for the examined taxa on an interspecific level. Consequently, seed morphology and anatomy with a few exceptions demonstrated diversity and they had taxonomic importance in terms of distinguishing among species.

The seed macro- and micro-morphological characters of 13 species belonging to three genera; Kickxia Dumort, Scrophularia L. and Plantago L., collected from different localities of Saudi Arabia, were studied using a Stereomicroscope and Scanning Electron Microscope for evaluating their taxonomic relationships. Three macro-morphological characters of seeds were shape, size, and color while three diagnostic micromorphological characters were seed coat sculpture, the anticlinal and periclinal wall., The seed shape seems to be specific in Plantago L. (peltate, angled) than the two other genera while the color and seed size show little importance. The Plantago L. has a specific rugose sculpture while the other two genera have either tuberculate or alveolate. So Plantago L. was possessed no affinities to Kickxia Dumor or Scrophularia L.. This observation gives extra support to the earlier taxonomic views that suggested the retention of two genera in the traditional family Scrophulariaceae and maintaining Plantago L. in a separate monogeneric family Plantaginaceae Detailed analysis of seed characters of more species is needed to clarify the systematic relationships between the three genera. A key to the identification of studied species based on seed micro- and macro-morphological characters is provide. Bangladesh J. Plant Taxon. 28(2): 385-393, 2021 (December)

In this study, the pollen morphology and exine structure of nine species of the genus Salvia L. (Lamiaceae) were investigated using light microscopy and scanning electron microscopy (SEM). Six micromorphological characters (pollen shape, polar length, equatorial width, exine and intine thickness, colpus length and colpus width) of pollen grains of Salvia have been identified. The palynological observations revealed that pollen grains of most studied taxa of Salvia were suboblate shape and possess hekzacolpate aperture. Tectal surface sculpture was a good criterion to identify particular taxa from Salvia. The pollen of which is characterized by reticulate, the pollen ornamentation was similar in all studied taxa.

The present study aims to evaluate the anatomy of leaf and stem as well as pollen morphology in two taxa, namely L. racemosus (Lam.) Tzvelev subsp. sabulosus (Bieb.) Tzvelev and L. cappadocicus (Boiss. & Bal.) Melderis. Also, it is targeted to contribute to the morphology of these two taxa. The results have revealed varying anatomical characters in the types of stomata, wall appearance of the long cells, indumentum densities, dispositions of sclerenchyma around the vascular bundles, girders and strand shapes of the sclerenchymatic cells in the leaves, epidermal cell arrangements and epidermal cell sizes in the attachment points with sclerenchyma in the stems. Moreover, alternation in the pollen morphology concerning pollen size, operculum, undulation and the number of scabrae has also been demonstrated.Keywords: Leymus; Anatomy; Leaf; Pollen; Taxonomy.DOI: 10.3329/bjpt.v18i1.7836Bangladesh J.

Comparative morphological and foliar anatomical studies were carried out on three species of Asplenium: Asplenium nidus L., Asplenium scolopendrium (L.) Newn and Asplenium barterii Hook with a view to identifying important morphological and anatomical characters that can be employed in the separation of the species. Mature healthy plants of each species were collected from Erin Ijesa Waterfall and nursed in the FernGarden of Natural History Museum at Obafemi Awolowo University, Ile-Ife. Morphological observations and measurements were documented for each species. The transverse sections of the petiole and stem foliar sections were prepared by cutting at 10 μm thickness using Reichert Sliding Microtome and microphotographs were taken. Quantitative data obtained from this study were subjected to one-way Analysis of Variance with Duncan Multiple Range Test for mean separation. Findings revealed that the predominantly irregular epidermal cells on the adaxial surface of A. barterii is diagnostic of the species. The presence of tetracytic stomata in addition to anisocytic type also separates A. nidus from the other taxa. Similarly, A. scolopendrium had a significantly higher guard cell area compared to the other taxa. Morphological and foliar anatomical features in  the genus can be used to delimit the three species while the possession of two vascular bundles broadly admit the species into the genus Asplenium.
