Seed Macro- And Micro-Morphology of Some Species Of Kickxia Dumort, Scrophularia L. And Plantago L. From Saudi Arabia

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)

Foliar trichomes of 21 species of the genus Croton L. from China have been examined using stereomicroscopy and scanning electron microscopy. Five trichome types characterized by their morphology are identified, viz., stellate, lepidote, simple, dendritic and appressed-rosulate. Only stellate trichome is observed in most species, with only six species that are found to maintain two or three trichome types. Trichome types and density are useful for species identification and sectional classification for Chinese species. Based on the trichome types and other morphological characters, 21 Chinese species are proposed to be placed in five sections. Croton crassifolius belongs to sect. Andrichnia; C. cascarilloides belongs to sect. Monguia; C. mangelong, C. kongensis, C. laevigatus and C. laniflorus belong to sect. Argyrocroton; C. lauioides, C. howii and C. damayeshu belong to sect. Adenophylli. The remaining Chinese Croton species might be placed into sect. Croton. A key for Chinese Croton species based on trichome morphology is provided.DOI: http://dx.doi.org/10.3329/bjpt.v20i1.15468Bangladesh J. Plant Taxon. 20(1): 85-94, 2013 (June)

Seed morphology of 12 Iranian endemic and subendemic species of Veronica was studied using scanning electron microscope (SEM). Seven qualitative and quantitative characters were measured using SEM micrographs and stereomicroscopy. The seed shape of most species is ovate and plano-convex. The size of seeds ranges from 1.25 x 0.75 mm in V. khorassanica to 2.5 x 1.75 mm in V. viscosa Boiss. The ornamentation of seed coat is reticulate-verrucate in V. khorassanica, V. czerniakowskiana, V. mazanderanae and V. rubrifolia, reticulate-rugate in V. acrotheca, V. aucheri, V. viscosa and V. intercedens, rugose in V. microcarpa, V. chionantha and V. rechingeri, and reticulate-porate in V. gaubae. The testa cells are polygonal in ten species and irregular in two species. Micromorphological characters of seeds are useful in specific and subspecific delimitations of Iranian Veronica.

Eleven Species

A revision of the Australian taxa of the genus Spergularia (Caryophyllaceae) on the basis of herbarium material, field studies and analysis of morphological characters necessitates realignment of some taxa and application of some neglected names, clarifying circumscription and understanding of the species of this genus. Eleven species are here recognised, with five considered indigenous, Spergularia nesophila and S. diandroides described as new and S. tasmanica transferred to Spergularia from Lepigonum. Fruits and seeds provide compelling diagnostic characters in this genus and are used in supplementary dichotomous and tabular diagnostic keys. Scanning electron micrographs (SEMs) illustrate key seed shape and surface features.

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.

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 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.

AbstractThe paper presents the results of the study on seed morphology of four following Ornithogalum species: O. boucheanum Asch., O. nutans L., O. pyrenaicum L., and O. umbellatum L. Several macro-and micro-morphological characters were observed using stereoscope and scanning electron microscope. Differences were found especially in micromorphological characters of the seed surface, the shape of raphe and micropylar pole. These characters can be used as an additional taxonomic criterion at specific level for this genus. Only the seeds of O. boucheanum and O. nutans — two closely related and morphologically very similar species are practically undistinguished.

Background: This paper investigates whether the fruit and seed micromorphology of eight Turkish Iberis (Brassicaceae) species can be used as a further aid in their taxonomic delimitation. Questions: Are the micro-morphological characters of the fruits and seeds of Iberis useful to support the taxonomic delimitation of its species? Studied species / data description /Mathematical model: The eight species of Iberis present in Turkey were examined. The fruit and seed characteristics were obtained and statistical analysis was performed using UPGMA. Study site and dates: Fifteen localities in Turkey, from 2015 to 2019. Methods: Samples of fruit and seed of eight species of Iberis were collected, stored, and later measured and described with aid of light and scanning electron microscopies. Results: All eight species had different fruit and seed characters; particularly differing from each other with respect to fruit and seed size, seed shape and seed ornamentation. Two fruit ornamentation types were evident, smooth and striated. The seed coat surface were separated into three types: reticulate, reticulate-rugose and reticulate-papillate, being reticulate the most common. Further differences were noted for the seed surface epidermal structures, notably species had rectangular, tetragonal, or pentagonal patterning. An identification key was constructed based on a similarity analysis. Conclusions: Fruit morphology, seed dimensions, colour, and epidermal cell patterning are useful microcharacters that enabled species-level determinations in the Iberis species sampled.
