The morphological and anatomical aspects of 13 species belonging to genera Kickxia, Scrophularia, and Plantago of Saudi Arabia reveal that the species of Kickxia and Scrophularia are distinct from Plantago major. The most notable morphological differences are the absence of adventitious roots and the presence of acaulescent stem in the species of Kickxia and Scrophularia and the existence of adventitious roots and the absence of acaulescent stem in P. major. The species of Plantago possessed rose-shaped radical leaves, whereas the rest of the species studied had cauline leaves or both. The species of Kickxia and Scrophularia have pentamerous flowers with bilabiate corollas, whereas, P. major has tetramerous flowers with tubular corollas. The separation of P. major from the rest of the studied species is the most obvious result obtained from the dendrogram, and this result is consistent with some traditional taxonomic studies that placed Kickxia in the Scrophulariaceae species while separating P. major into an independent family Plantaginaceae. The anatomical findings revealed that the upper and lower epidermal cells of the leaves were irregular with undulate walls in all analyzed species, except in P. major, where they were polygonal with straight walls. Only P. major had amphianisocytic paracytic stomata, but eight Kickxia species had anomocytic stomata and K. hastata and K. abhaica, and the two Scrophularia species had anisocytic stomata. Therefore, this study suggests the retention of the Kickxia in Scrophulariaceae s.l. and maintaining Plantago in Plantaginaceae s.s. Bangladesh J. Plant Taxon. 29(1): 1-11, 2022 (June)

The family Tropaeolaceae was reported for the first time in Saudi Arabia. The new record (Tropaeolum majus L.) from the Tropaeolaceae family was found in damp and exposed semi-shaded habitats between roughly 1800 and 2132 m elevation in southwestern Saudi Arabia. Illustrations, photos, taxonomic description, distribution map, key and information about the habitat of the plant were given. This study suggests that the new record is an introduced alien plant into Saudi Arabia. Bangladesh J. Plant Taxon. 29(1): 79-84, 2022 (June)

Cardiovascular diseases (CVDs) are one of the major causes of death in the world. Medicinal plants with thrombolytic properties may be used as an alternative to modern medicines for CVDs. The present study was aimed to evaluate the thrombolytic potential of six medicinal plants available in Bangladesh using an in vitro clot lysis method where streptokinase and ethanol were used as a positive and negative control, respectively. Ethanolic extract at a dose of 10 mg/ml of Arjun tree (Terminalia arjuna), Garlic (Allium sativum), Elephant apple (Dillenia indica), Amla (Phyllanthus emblica), Yellow mombin (Spondias pinnata) and Burmese grape (Baccaurea ramiflora) showed 14.18 ± 1.23%, 10.72 ± 0.78%, 8.25 ± 0.42%, 7.08 ± 0.64%, 5.42 ± 0.47% and 2.47 ± 0.19% clot lysis, respectively, whereas the standard drug streptokinase lysed 41.11±0.31% clot at a dose of 30,000 IU. From the data, it is evident that ethanolic extracts of six selected medicinal plants possess a moderate to insignificant thrombolytic activities. Among these plants, Arjun tree and Garlic exhibited the highest thrombolytic activity and the Burmese grape showed the lowest thrombolytic activity. Through our study, it could be concluded that Arjun tree, Garlic, and Elephant apple might be used as traditional healing purposes of CVDs. However, further animal studies will prove the scientific justification of their uses. Conservation efforts should be given for Arjun tree, Elephant apple, Yellow mombin, Burmese grape, and Amla to save these plants from extinction in nature. Bangladesh 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.

Stem anatomical features of four Sesbania Scop. species viz. S. bispinosa (Jacq.) W. Wight, S. cannabina (Retz.) Poir., S. sesban (L.) Merr., and S. rostrata Bremek. & Oberm., were examined to add some insights for identification of these species using quantitative anatomical descriptors. Sesbania stem is composed of epidermis, cortex, vascular tissues – phloem, cambium zone and xylem, and pith, which exhibit significant variations among the species in terms of their area and thickness. Sesbania sesban showed the largest area and widest epidermal cells. The close relationship between S. bispinosa and S. rostrata was found in the stem anatomical descriptors. Moreover, S. rostrata and S. cannabina were closer to some extent according to some anatomical descriptors; also rationalizing the external morphological similarities of these species. A dichotomous key of the studied Sesbania species was made. Dendrograms based on Agglomerative Hierarchical Cluster analysis of stem anatomical descriptors also confirmed close relationships identified in previous phylogenetic analyses. Bangladesh J.

Salacia comprises 200 species throughout the tropical countries. In Sri Lanka, five species of this genus S. chinensis, S. diandra, S. oblonga, S. reticulata and S. acuminatissima are recorded that are considered as the synonyms under S. diandra by Wadhwa in 1996 during the revision of genus. These species are very much similar in vegetative morphology and their flowering is irregular and rare. Due to these reasons, their proper identification and determination are difficult and identification of new combinations of taxonomic characters is necessary. A multivariate analysis was conducted for 98 distinct populations using 20 vegetative and 43 leaf anatomical characters including PCA, PCO, CA, SIMPER and correlation analysis. The results support the recognition of four phenetic groups, which corresponds to species S. chinensis, S. reticulata, S. oblonga and S. diandra. S. acuminatissima that was recognized by Kostermans (1992) was not supported by the analysis and formed a cluster together with S. diandra with no support as a separate cluster. The study failed to recognize any distinct vegetative characters to define these taxa but propose a combination of vegetative or leaf anatomical characters and also highlights the necessity of molecular data to supplement the vegetative and leaf anatomical data to resolve the ambiguity between the S. acuminatissima and S. diandra.

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)
