Abstract. Fugarasti H, Muzzazinah, Ramli M. 2020. Morphoanatomy of three Indigofera species (Leguminosae-Papilionoideae) in Java Indonesia. Biodiversitas 21: 5531-5538. This study aimed to explore the morphological and detailed anatomical features of the stems, leaves, and roots from three Indonesian Indigofera species. Morphological-anatomical studies of three Indonesian Indigofera species were carried out using embedded microscopic preparations. The anatomical characters of the specimens were observed using a compound optical microscope with magnification 40x, 100x, and 400x. The observation showed the anatomical cross-section of  I. tinctoria stem was rectangular, I. suffruticosa was hexagonal, and I. arrecta was rounded. The tissue structures of Indigofera species, from the outside layer, were the epidermis, thin cortex, secondary phloem (narrow or wide), thick secondary xylem, and conspicuous pith in the middle. Whilst, the corner of I. suffruticosa stem contained thick collenchyma. The vascular bundles were the open collateral. The leaves of Indigofera species are made up of the upper epidermis, mesophyll (palisade parenchyma, spongy parenchyma), and the lower epidermis. The vascular bundles were located in the middle, with five or six segments of the xylem elements and small groups of phloem elements, all in the parallel lines. The primary stele type of the roots is actinostele, cambium activity pushed him aside. The vascular bundle of the roots consisted of a dense and tight secondary xylem composed of thick-walled circular vessels (mostly tightly arranged). Data about the morphoanatomy structure of three Indonesian Indigofera species could complement the novelty of the morpho-anatomy information records obtained by previous researchers.

AbstractIn this study, the anatomical features of the leaf and stem, besides the nutlet characteristics of some Teucrium sect. Isotriodon (Lamiaceae) taxa in Turkey, T. montbretii Betham subsp. montbretii, T. montbretii subsp. pamphylicum P. H. Davis, T. odontites Boiss. & Bal., T. cavernarum P. H. Davis, T. antitauricum T. Ekim, along with an isolated population of T. montbretii (T. montbretii subsp.) were investigated. The anatomical studies revealed that the taxa share generally similar anatomical characters, such as thicker upper leaf cuticles and larger upper leaf epidermal cells compared to lower ones and diacytic to anomocytic stomata on the leaves. However, the portion of the mesophyll occupied by palisade parenchyma and the occurrence of mucilage cells in leaf epidermis shows difference among the taxa. Furthermore, the studied taxa have general stem characteristics of the Lamiaceae family, except for having poorly developed collenchyma at the corners. With the amphistomatic leaves and developed sclerenchymatic tissue in the leaf median vein, T. cavernarum is seperated from the other taxa. Trichome types on the vegetative organs and nutlet shape and sculpturing are generally the same or similar in the studied taxa, but trichomes on the nutlets are different among them. Based on nutlet characteristics and some morphological ones, it was revealed that the isolated population of T. montbretii represent a new subspecies, T. monbretii subsp. yildirimlii M.Dinç & S.Doğu subsp. nov.

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.

Teucriumalyssifolium Stapf (endemic), Teucriumpestalozzae Boiss. (endemic) and Teucriumbrevifolium Schreb. are three closely related taxa in Teucriumsect.Teucrium. The obtained data from the anatomical studies revealed that these three taxa represent the general anatomical characteristics of the Lamiaceae family. Leaves, anatomical features such as thick cuticle, abundant trichomes, rich palisade parenchyma layer in the mesophyll provide evidence that these three species are xeromorphic structures. Leaf and stem anatomy showed that the taxa have generally similar anatomical features. However, cuticle layers, epidermis cells size, indumentum density, mesophyll types, palisade parenchyma occupied in the mesophyll, presence of spherocrystals in leaves and parenchyma, collenchyma and sclerenchyma layers in stems show differences amongst the taxa. Anatomical characters of leaf and stem of these taxa are examined for the first time in this study.

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.

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

Heliotropium spp. is distributed worldwide mainly in tropical and subtropical regions, with dry and warm temperate to semi-arid regions so that Southwest and center of Asia have considered as the main centre of origin and diversity of Heliotropium genus. Iran, with 32 species and 14 (sub) endemic species, has the highest diversity in the world followed by Pakistan and Turkey with 15 species and only one endemic species and the Arabian Peninsula with 15 species and three endemic species are in the next ranks. In order to anatomical studies on Heliotropium, twelve species of this genus were selected from different regions of Iran. The selected species included: H. bacciferum Forssk., H. ramossisimum BGE., H. brevilimb Boiss., H. transoxanum BGE., H. dasycarpum Ledeb, H. dyginum Forssk., H. aucheri Dc., H. carmanicum BGE. As perennial group and H. ellipticum Ledeb., H. lasiocarpum Fisch., H. suaveolens M.B. as annual group. In order to add more data to leaf anatomy characters, evaluating of systematic relevance and/or adaptive value of the morphological and anatomical diversity we have studied 24 anatomical characters in theses 12 species. For example shape and vascular bundles of main midrib, type of parenchyma cells located under lower epidermis of midrib, distance between vascular bundles and lower or upper epidermis, angle of between two parts of blade, number of cellular layers in lower or upper mesophylla, length of upper and lower mesophylla, type of cell wall in lower and upper mesophylla and thickness of lamina were investigated in this study. In order to this present obtained H. aucheri can be separated from H. carmanicum in H. aucheri subsp. carmanicum. It can be conclude that two species H. aucheri and H. carmanicum are independent species and can accept H. transoxanum as a sub group of H. dasycarpum.

The current study presents investigations on the scape anatomical characteristics of Urginea indica population, a geophyte growing in India, Africa and Mediterranean regions. For scape anatomical studies transverse sections of inflorescence axis were taken and studied for the first time. The twelve different population studied revealed that outer most epidermis of inflorescence is covered by thick cuticle. Cortex is differentiated into 3 regions outer chlorenchyma, middle collenchyma and inner parenchyma. But the shape and number of rows of cells vary in different populations collected from various localities of Karnataka. Vascular bundles are arranged in 3 rows, 2 rows in few populations and number. of vascular bundles vary. Larger bundles varies from 5-8, medium 8-12 and smaller bundles 5 to 21 in number. Xylem elements are uniseriate and biseriate in few. Some populations show Myelin structures and cell inclusions, based on their ecological habitat. The distinctions among cross sections of scapes are evident and our findings offer a comprehensive study using anatomical traits for delimitation and diagnosing populations of U.indica providing a platform for further taxonomic investigations.

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.

Lignin in the middle lamella of the secondary xylem of angiosperms appears to be inhomogeneously distributed, based on studies where the focus is on a close examinantion of the middle lamella region of fibre cell walls by transmission electron microscopy (TEM). This is in contrast to the secondary xylem of gymnosperms which often display a more uniform distribution of lignin in the middle lamella of secondary xylem elements. The aim of our study was to undertake TEM examination of kenaf (Hibiscus cannabinus L.), an angiosperm plant mainly cultivated for its high quality secondary phloem fibres, to investigate lignin distribution in the middle lamella of secondary vascular tissues, including secondary phloem fibres. The middle lamella displayed considerable heterogeneity in the distribution of lignin in all lignified secondary vascular tissues, including xylem and phloem fibres, vessels and axial xylem parenchyma cells. The results provided evidence of lignin inhomogeneity in the secondary phloem fibres as well as in other lignified elements of kenaf vascular tissues, extending previous observations which were confined only to fibre cells.
