Chapter-3 Plant Kingdom 1. the System of Plant Classification
NEET Questions- Chapter-3 Plant Kingdom 1. The system of plant classification proposed by Carolus Linnaeus was artificial because a) It was based on evolutionary relationship of plants b) It was based on similarities and differences in floral and other morphological characters only c) It took into account the physiological facts along with the morphological characters d) None of the above 2. Linnaeus is credited with introducing a) The concept of inheritance b) Law of limiting factor c) Theory of heredity d) Binomial nomenclature 3. Out of the 4 widely known systems of classification one remains less phylogenetic and more natural and that is of a) Engler and Prantl b) Hutchinson c) Bentham and Hooker d) Rendle 4. The chief merit of Bentham and Hookers classification is that a) it is a natural system of classification of all group of plants b) a system based on evolutionary concept c) it also considered the phylogenetic aspect d) The description of taxa are based on actual examination of the specimens 5. ‘SystemaNaturae’ written by Linnaeus contains a list of a) 4000 species of plants b) 2000 species of plants c) 4200 species of plants d) 4200 species of animals 6. Natural system of classification of plants differs from artificial system of classification in a) taking into account only one vegetative character b) taking into account only one floral character c) taking into account all the similarities between plants d) all of these 7. One of the best methods for understanding general relationships of plants is a) Cytotaxonomy b) Experimental Taxonomy c) Numerical Taxonomy d) Chemotaxonomy 8. -

Phylogeny and Classification of the Melastomataceae and Memecylaceae
Nord. J. Bot. - Section of tropical taxonomy Phylogeny and classification of the Melastomataceae and Memecy laceae Susanne S. Renner Renner, S. S. 1993. Phylogeny and classification of the Melastomataceae and Memecy- laceae. - Nord. J. Bot. 13: 519-540. Copenhagen. ISSN 0107-055X. A systematic analysis of the Melastomataceae, a pantropical family of about 4200- 4500 species in c. 166 genera, and their traditional allies, the Memecylaceae, with c. 430 species in six genera, suggests a phylogeny in which there are two major lineages in the Melastomataceae and a clearly distinct Memecylaceae. Melastomataceae have close affinities with Crypteroniaceae and Lythraceae, while Memecylaceae seem closer to Myrtaceae, all of which were considered as possible outgroups, but sister group relationships in this plexus could not be resolved. Based on an analysis of all morph- ological and anatomical characters useful for higher level grouping in the Melastoma- taceae and Memecylaceae a cladistic analysis of the evolutionary relationships of the tribes of the Melastomataceae was performed, employing part of the ingroup as outgroup. Using 7 of the 21 characters scored for all genera, the maximum parsimony program PAUP in an exhaustive search found four 8-step trees with a consistency index of 0.86. Because of the limited number of characters used and the uncertain monophyly of some of the tribes, however, all presented phylogenetic hypotheses are weak. A synapomorphy of the Memecylaceae is the presence of a dorsal terpenoid-producing connective gland, a synapomorphy of the Melastomataceae is the perfectly acrodro- mous leaf venation. Within the Melastomataceae, a basal monophyletic group consists of the Kibessioideae (Prernandra) characterized by fiber tracheids, radially and axially included phloem, and median-parietal placentation (placentas along the mid-veins of the locule walls). -
Two New Genera in the Omphalodes Group (Cynoglosseae, Boraginaceae)

Our work is focused both in the internal relationships among representatives of Omphalodes main subgroups (and including Omphalodes verna, the type species), and their relationships with other Cynoglosseae genera that have been related to the Omphalodes group. Our phylogenetic analysis of ITS and trnL-trnF molecular markers establish close relationships of the American Omphalodes with the genus Mimophytum, and also with Cynoglossum paniculatum and Myosotidium hortensia. The southwestern European annual Omphalodes species form a discrete group deserving taxonomic recognition. We describe two new genera to reduce the paraphyly in the genus Omphalodes, accommodating the European annual species in Iberodes and Cynoglossum paniculatum in Mapuchea. The pollen of the former taxon is described in detail for the first time. Keywords: Madrean-Tethyan, phylogeny, pollen, systematics, taxonomy Resumo Neste estudo analisamos as relacións filoxenéticas deOmphalodes (Boraginaceae, Cynoglosseae) no contexto da tribo Cynoglosseae, confirmándose como parafilético o xéneroOmphalodes . -

Abstract Plant small RNAs (sRNAs) are important regulatory elements that fine-tune gene expression and maintain genome integrity by silencing transposons. They have critical roles in most pathways involved in plant growth and reproductive development. Reproductive organs of monocots produce abundant phased, small interfering RNAs (phasiRNAs). The 21-nt reproductive phasiRNAs triggered by miR2118 are highly enriched in pre-meiotic anthers, and have not been described in eudicots. -

Please cite this article as doi: 10.1002/spp2.1221 This article is protected by copyright. All rights reserved A ‘Gempylids’ (snake mackerels) and trichiurids (cutlassfishes) are pelagic fishes characterised by slender to eel-like bodies, deep-sea predatory ecologies, and large fang-like teeth. Several hypotheses of relationships between these groups have been proposed, but a consensus remains elusive. Fossils attributed to ‘gempylids’ and trichiurids consist almost exclusively of highly compressed body fossils and isolated teeth and otoliths. We use micro-computed tomography to redescribe two three- dimensional crania, historically assigned to †Eutrichiurides winkleri and †Progempylus edwardsi, as well as an isolated braincase (NHMUK PV OR 41318). -

ISSN 2325-4785 New World Orchidaceae – Nomenclatural Notes Nomenclatural Note – Issue No. 70 www.newworldorchidaceae.com April 7, 2020 A New Species of Brassiopsis Szlachetko & Górniak (Orchidaceae) is Described From Colombia. (With spanish translation) Ruben P. Sauleda1 and Carlos Uribe-Velez2 16442 SW 107 Ct. Miami, Fl, 33173. 2Calle 115 #5-23 Bogota, Colombia. Abstract A new species of Brassiopsis Szlachetko & Górniak is described from Colombia, Department of Risaralda. John Lindley established the genus Ada in Folia Orchidaceae (1883-1854) based on Ada aurantiaca, a Colombian species. Lindley divided the genus Brassia, established in Hortus Kewensis 1813 by Robert Brown, into two sections, Eubrassia and Glumaceae. He recognized that Ada and the glumaceous brassias were similar, but gave four characters, which separated the two groups from Ada. However, examination of living material does not support the separation on the characters that Lindley stated. The most distinctive feature between the two groups Eubrassia and Glumaceae and Ada is the lamellae on the labellum. Williams (1972) emended the genus Ada as described by Lindley to include species in the Brassia section Glumaceae. Based on Williams (1972) the genus Ada consists of eight species: Ada aurantiaca Lindl., Ada farinifera (Linden & Rchb. f.) N. H. Williams, Ada chlorops (Endr. & Rchb. f.) N. H. Williams, Ada elegantula (Rchb. f.) N. H. Williams, Ada allenii (L. O. Williams ex C. Schweinf.) N. H. Williams, Ada keiliana (Rchb. f. ex Lindl.) N. H. Williams, Ada glumacea (Lindl.) N. H. Williams, and Ada ocanensis (Lindl.) N. H. Williams. Williams (1972) based his results on morphological analysis. Neubig et al.
