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.

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

AbstractIn this study, pollen grains and anatomical features of Turkish lilies were investigated under the electron (SEM) and light (LM) microscope. LM and SEM observations showed that the pollen grains are monosulcate, heteropolar, elliptical in polar view and oblate. Numerical results based on combined palynological and anatomical characters were discussed and compared with traditional taxonomic treatments. It was found that the midrib shape, mesophyll type, P/E (polar/equatorial), sulcus length, and lumina width are the most valuable traits in separating the examined taxa. The numerical analysis showed that Lilium candidum L. differs from the rest Turkish Lilium and also confirmed a close relationship between L. szovitsianum Fisch. & Avé-Lall. and L. armenum Miscz. ex Grossh. Also this study is the first report dealing with anatomical and palynological features of all Turkish lilies.

AbstractThe gross anatomical features, namely stem, blade and petiole and the micromorphological features, trichome, pollen and nutlet of Salvia vermifolia Hedge & Hub.-Mor. (Sect. Aethiopis Bentham, Lamiaceae) were examined using light microscopy (LM) and scanning electron microscopy (SEM). S. vermifolia is a perennial endemic herb growing on igneous and serpentine slopes in Sivas province, Central Anatolia, Turkey. The results obtained from anatomical studies show that the stem is made up of 4–8-layers of collenchyma cells and 1-3-layers chlorenchyma cells. The blade is amphistomatic, bifacial, with 2-3-layered palisade cells on the adaxial. The petiole has three large central bundles and six small subsidiary bundles. Peltate glandular, capitate glandular and non-glandular trichomes are present in S. vermifolia. The peltate glandular trichomes are present in abundance on the calyx and corolla, and capitate glandular trichomes are predominant on the calyx, inflorescence axis, pedicel and stem. The acicular non-glandular trichomes are mainly situated on the calyx, corolla, inflorescence axis and pedicels whereas the floccose non-glandular trichomes are common on both sides of the leaf, inflorescence axis and petiole. The pollen grains are hexacolpate to octacolpate, medium to large (P, polar axis=45.29–62.49 μm; E, equatorial axis=45.32-62.38 μm), oblate-spheroidal to prolate-spheroidal (P/E=0.91–1.02) and their exine ornamentation is bireticulate. The nutlets are 2.70–2.90 mm long and 1.90–2.13 mm wide, brown, ovoid-oblong in their outline, rounded-trigonous in transverse section, and their surface is glabrous and colliculate.

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.

The pollen grains of 19 Turkish Salvia species in Aethiopis, Drymosphace, Hemisphace, Hymenosphace and Salvia sections, 13 of which are endemic to Turkey, were investigated, documented and illustrated through Light Microscopy (LM) and Scanning Electron Microscopy (SEM). This study provides pollen data of 14 species for the first time. The pollen grains of the species examined are monads, isopolar, radially symmetrical and hexacolpate, mostly medium in size, slightly elliptic to more or less circular in polar view and mainly oblate-spheroidal in equatorial view. Two different ornamentation types are recognized on exine sculpturing; reticulate-perforate and bireticulate. The present results do not generally support the traditional infrageneric classification of Salvia, but provide useful pollen characters for species delimitation.

Haplophyllum Myrtifolium

Haplophyllum is one of the taxonomically difficult genera in the Rutaceae. Three Turkish endemic species of Haplophyllum, namely Haplophyllum myrtifolium, H. vulcanicum and H. megalanthum, have similar morphological features, therefore identification of the species are extremely difficult. In the present study, morphological, anatomical and palynological characteristics of the species are examined in order to understand the usefulness of these characteristics for systematics purposes. Morphological characteristics of leaves and corollas, absence/or presence of glandular hairs on the stem and inflorescence, expansion form of filaments and ovarium appendage are useful for specific delimitation among the species. Anatomical characters such as number of cortex layers and sclerenchymatic cell layers in stem, size of the vascular bundle in the midrib provide information of taxonomical significance. In addition, exine sculpturing pattern of pollen grains can be used for taxonomic purposes.

AbstractIn this study, the anatomical features of the leaf and stem, besides the pollen and nutlet characteristics of Teucrium sandrasicum are investigated. T. sandrasicum, belonging to sect. Teucrium, is an endemic perennial herb growing on serpentine around Muğla province. The anatomical studies on T. sandrasicum revealed that the stem shares the general characteristics of the Labiatae family. The leaves clearly exhibit xeromorphy due to features such as the distribution of stomata on the lower surface (hipostomatic), the occurrence of guard cells below the epidermis (xeromorphic type), inrolled margins, thick cuticle layer, thick outer epidermal cell wall, a high density of trichomes and thick palisade layer of the mesophyll. The anatomical studies showed that the upper epidermal cells of the leaf include many spherocrystals. The pollen grains are prolate, medium in size, 3-colpate with verrucate ornamentation. The nutlets are ellipsoid with a reticulate-verrucate surface. The results have proven that T. sandrasicum is different from the other species of the sect. Teucrium because of the branched trichomes on the stem and the lack of eglandular trichomes on the nutlets.

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.

In this study, pollen micromorphological structure, leaf and stem anatomy structure of six species of Onopordum (O. acanthium L., O. armenum Grossh., O. carduchorum Bornm. & Beauv., O. carmanicum (Bornm.) Bornm., O. heteracanthum C. A. Mey and O. leptolepis DC) were examined with different repetitions. About 17 qualitative anatomical features were statistically analyzed. Glandular trichome, cortex fiber tissue, embowed in subsidiary vascular, its fiber tissue and vascular sheath extensions, adaxial collenchyma tissue and types of adaxial and abaxial stomata were distinct characters in separating of the species. In palynologic studies based on P/E ratio, 2 types of pollen grains were observed: oblate- spheroidal and suboblate. SEM study of the exine showed echinate, reticulate and perforate sculpturing in all six species.

Anatomical Characters

A comparative anatomical study was made of the genus Passerina comprising 20 species and four subspecies, most of which are endemic to southern Africa. It showed that anatomical variation is useful in species recognition and classification. Anatomical characters typical of Thymelaeaceae and displayed in Passerina include isobilateral leaves, a papillate cuticular membrane, mucilaginous epidermal cell walls, a parenchymatous bundle sheath and extraxylary sclerenchyma fibres. Vascular bundles of the leaf lack intraxylary phloem. Characters common to  Passerina are inverse-dorsiventral and epis- tomatic leaves, inverted palisade parenchyma and an abaxial hvpodermal sclerenchymatous sheath. Orientation of the main vascular bundle in relation to the epidermis and mesophyll allows the recognition of four leaf structural types and ten states, according to which all species can be characterized and grouped. Functionally many anatomical features of the leaf in Passerina are interpreted as adaptations to the Mediterranean climate of the Cape Floristic Region, where most species occur.
