Conda Inocencio E. Buot, Jr <p><span style="background-color: #ffffff;">The present study was conducted to delineate <em>Diplazium</em> Swartz species based on leaf architecture. Using PAleontological STatistics (PAST), a cluster and Principal Component Analysis of leaf architecture characters of 27 selected <em>Diplazium</em> species at the Philippine National Herbarium (PNH) was done. The dendogram (cophenetic correlation = 0.8436) and principal component analysis supported the four clusters of <em>Diplazium</em> using leaf architecture characters. At Gower distance of 0.25, <em>Diplazium </em>species were categorized as: Cluster 1 (Cladodromous – short stalked, stout and massive 1° vein); Cluster 2 (Reticulodromous – long stalked, moderate 1° vein); Cluster 3 (Craspedodromous – long stalked, stout to massive 1° vein); and Cluster 4 (Craspedodromous – short stalked, stout to massive 1° vein). The unifying characters were apex shape, base symmetry and 1° vein category, while the significant differentiating characters were 2° vein angle of divergence and variation in the 2° vein angle of divergence, 3° vein category, 3° vein angle of divergence, variation in 3° vein angle of divergence, 3° vein spacing and lobation. The successful delineation of<br><em>Diplazium</em> species proved that leaf architecture can be a good taxonomic marker and could be an alternative way of identifying species in the absence of sori.</span></p> 2018-12-29T13:05:40+00:00 ##submission.copyrightStatement## A comparative study of achene morphology in Korean Polygonaceae 2018-12-29T13:31:05+00:00 Min-Jung Kong Jun-Ho Song Beom-Cheol An Sung-Won Son Gang-Uk Suh Mi-Jin Chung Suk-Pyo Hong <p><span style="background-color: #ffffff;">A comparative macro- and micromorphological study was conducted on achenes of Korean Polygonaceae comprising 45 taxa under 10 genera using a Stereo-microscope (SM) and Scanning Electron Microscope (SEM) to evaluate the taxonomical relevance of achene morphological characteristics. The achene shape is lenticular, biconvex, trigonous, or spheroidal. The largest achenes are found in <em>Fagopyrum esculentum</em> Moench (5.80–6.70 × 3.90–4.40 mm) and <em>Rheum rhabarbarum</em> L. (5.00–6.50 × 4.00–5.20 mm), and the smallest is found in <em>Rumex maritimus</em> L. (1.17–1.41 × 0.60–0.84 mm). Three types of embryo shape (curved, straight, and folded) and two types of embryo position (plane and parietal) can be distinguished. Most taxa have a curved embryo shape with plane position. Four types of surface patterns (smooth, papillae, tuberculate, or small pits) are observed. The surface sculpture or embryo type is rather consistent at the generic or tribal level, and the comprehensive consideration of achene characteristics is also useful at the species level. The achene morphology is described in detail, compared, and illustrated. The taxonomic significance of the achene morphology is discussed.</span></p> 2018-12-29T13:26:48+00:00 ##submission.copyrightStatement## Molecular identification of Lavendula dentata L., Mentha longifolia (L.) Huds. and Mentha × piperita L. by DNA barcodes 2018-12-31T12:48:53+00:00 Shawkat Mahmoud Ahmed <p><span style="background-color: #ffffff;">Five DNA barcodes were tested for identification and discrimination of <em>Lavendula dentata</em> L., <em>Mentha longifolia</em> (L.) Huds. and <em>Mentha</em> × <em>piperita</em> L. New DNA barcodes have been registered for <em>L. dentata</em> from Taif, Saudi Arabia. The separate clading of <em>L. dentata</em> and <em>M. longifolia</em> through the phylogenic analyses proved their endemism to Saudi Arabia. The phylogenetic trees revealed from the ITS2, matK and trnH data demonstrated that all <em>Mentha</em> species formed monophyletic clusters except hybrid <em>M.</em> × <em>piperita</em> from Taif which formed separate clades distinguishing it from the two parents; <em>M. aquatica</em> L. and <em>M. spicata</em> L. DNA barcoding could be considered as a good approach for distinguishing and identifying the mint plants, though it was not possible to confirm the relationship between hybrids and their putative parents.</span></p> 2018-12-29T09:50:28+00:00 ##submission.copyrightStatement## A new species of Glyphis Ach. and three new records of Graphis Adans.

Sutton in the genus Nanorrhinum (Plantaginaceae): Evidence from its nuclear ribosomal DNA sequences 2018-12-31T12:57:44+00:00 M. Ajmal Ali <p><span style="background-color: #ffffff;">The nuclear ribosomal DNA (nrDNA) internal transcribed spacers (ITS) sequences is extensively used in the plant molecular phylogenetics for plant taxonomic identification and DNA barcoding purposes because the nrDNA ITS gene is easy to amplify by using the universal primers, its length is shorter and thus easy to sequence, and has strong discrimination power to distinguish the taxon at the species level. The present molecular phylogenetic analysis of ITS nrDNA sequences focuses to determine the taxonomic status of an unresolved endemic taxon <em>Kickxia abhaica</em> D.A. Sutton (Family Plantaginaceae, tribe Antirrhineae) reported from Saudi Arabia. The analysis supports the transfer of <em>K. abhaica</em> under the genus <em>Nanorrhinum</em>.</span></p> 2018-12-29T11:04:43+00:00 ##submission.copyrightStatement## Morphological, anatomical and cytological investigations on three taxa of Centaurea L.
